3 Page 3 of 22 PREFACE This manual has been prepared to provide minimum standards for Markdom Plastic Products Limited tooling suppliers concerning tool design, tool construction and tool progress reporting. We ask that any exceptions to these standards be noted on Markdom s request for quotations. Final approval of any exceptions must be made during a design review or pre-tool meeting. Suppliers are not to deviate from the standards contained in this manual unless they have received written authorization from Markdom. When quoting please reply in the format that the quote was received in, unless directed otherwise. If you have exceptions or require notes please add them as required on the quote form. Upon placement of business you may be required to complete a cost breakdown summary as required.

4 SUPPLIER RESPONSIBILITY Page 4 of 22 All tooling must be designed and constructed to meet or exceed the standards contained in this manual. The Tool supplier (the party to which Markdom has awarded a purchase order for construction of the tool) has the final responsibility for producing a tool that will make parts that are within tolerance and the statistical requirements of both the math data and the drawing. If the subject parts cannot be made according to the Markdom approved tool design, the necessary corrections and/or additions to the tool will be made at the supplier s expense. Any Math Data provided to you must be verified against any drawing that is provided to you. Any discrepancies must be noted and brought to our immediate attention; direction must be provided by Markdom before proceeding any further. Math Data shall be transmitted in either UG or the native file format as received. You may be required to attend a design review meeting at Markdom in addition to a pretool or pre-grain meeting (if applicable) at our customer s or the graining source location. The supplier will be responsible for the submission of a tool progress report before the close of business each Friday for the duration of the project. Any changes in the delivery schedule shall be communicated in writing immediately to Markdom Purchasing. All tools exceeding 4000 lbs must be delivered on a flat bed truck. Markdom will not unload tools from pick-up trucks if the tool exceeds 4000 lbs. All tools will be sampled at Markdom, unless otherwise agreed upon in writing. All tool samplings performed at alternate locations are the responsibility of the tool supplier, but must have had prior approval from Markdom. The supplier is required to be present during the sampling of the tool.

5 SAMPLING Page 5 of 22 Each tool will have three samplings that are included as a condition of purchase. Tool samplings exceeding three samplings may be charged back to the supplier as applicable. These costs may include any material consumed as well as any applicable layout time. Suppliers are responsible to provide sufficient notice when delivering tooling so that we may make the required arrangements in the schedule. Suppliers are required to be present during the sampling of tools and whenever possible the actual builder of the tool is the preferred choice. Following the sampling of the tool, you will be provided with a tool sampling report detailing all corrections that are required. This form is to be completed and returned to Markdom prior to returning the tool. CANCELLATIONS If tooling is cancelled for any reason, cancellation costs shall be determined by the status of completion as indicated in the most recent tool progress report received as well as the original cost breakdowns submitted. All costs are subjected to audit, and require complete support documentation for materials, labour and any subcontracted services. Markdom reserves the right to cancel a tool at any time during the construction phase. You are required to stop all tooling construction, both internal and external immediately upon being notified to do so. Any associated costs following notification will not be paid out to you.

6 DESIGN APPROVAL Page 6 of 22 A preliminary tool design (2 sets required) from the tool supplier must be submitted to Markdom for approval before any tool construction or ordering of steel / components commences. Preliminary mould designs must include: plan of core and cavity center cross section of the tool both longitudinally and across the width part position runner and gate location parting lines cooling lines (an additional isometric view of core & cavity cooling is required) part ejection and/or lifter layout tie bars of primary and secondary machines When required, you will also need to provide a marked up part drawing showing the parting line, ejector pin and gate locations, as well as any slide draws if applicable. Following the approval of the preliminary tool design the supplier is responsible to submit a fully detailed tool design (1 set required) to Markdom for final review and approval. Approval is required before any tool construction commences. The supplier is responsible to record all changes to the design during the tool construction and to maintain an up to date tool design. The supplier is responsible to provide Markdom with the final tool design layout in UG 3D format and the final detailed design on a CD in UG 3D format after tool approval. The BILL OF MATERIALS listing is also to accompany both. Design approval by Markdom, does not absolve the tool supplier of accountability for proper tool function.

7 Page 7 of 22 GENERAL DRAWING REQUIREMENTS All designs must have a plan view of the cavity, a plan view of the core, a longitudinal cross section (Sec. A-A ), typical cross sections through all major areas of the mould, and any auxiliary cross sections required to clarify mould conditions. All mould inserts are to be 100% (one hundred percent) detailed. Use the 0-0 datum line method to detail all mould components. Use the top of the tool on the non-operator side as the starting point. When several mould components are drawn on one sheet, all related views should be separated from the other details by dividing lines. All designs must have a complete bill of materials, including standard commercial mould components. All designs must be ballooned with split indicators containing the detail number and the sheet number that it is dimensioned on. Each sheet of a design must have a title block in the lower right hand corner. Regrind percentage based upon the tool design is to be provided with each revision and should be contained within the title block. In the case of hot runner tools you will be required to provide the volume of material contained within the complete system as well as providing a wiring diagram for the system. Symmetrically opposite mould sections must be assigned different detail numbers (example: detail 10 shown, detail 11 opposite). All designs must be drawn on standard D or E size paper with a 1/2 border (for print purposes only). All drawings must be numbered and dated. All revisions must be numbered and dated and a revision history should be present and current.

8 CONSTRUCTION TOLERANCES Page 8 of 22 Part drawing tolerances are manufacturing tolerances only and should be used as a guide for mould construction. Critical dimensions must exhibit statistical capability of greater than 1.67 CPK +/- 4 standard deviations. Dimensional tolerances for tool construction shall be arrived at as follows: A). Construction tolerances should be predicated on cavity to cavity identically and designated dimensional characteristics should be held to a tolerance that will satisfy repeatability within a 1.67 CPK with +/- 4 standard deviations. Information charted below is a demonstration of maximum tooling tolerance per print tolerance for non-designated dimensional characteristics. PART PRINT TOLERANCE CONSTRUCTION TOLERANCE +/-0.05 mm +/-0.02 mm +/-0.10 mm +/-0.05 mm +/-0.20 mm +/-0.10 mm +/-0.50 mm +/-0.15 mm B). C). D). E). F). The maximum tolerance to be used on any dimension not covered in (A) shall not exceed +/-0.20 mm. Angle tolerance shall not exceed 50% of that shown on part drawing. Ensure that you have been provided all relevant data such as machine data, material shrinkage and the intended cycle time. All dimensions should be made to nominal unless tolerances or instructions as provided by Markdom dictate otherwise. Steel safe conditions will be established upon completion of preliminary tool drawings where applicable.

9 SAFETY REQUIREMENTS Page 9 of 22 All slides must be equipped with a positive holding device to keep the slides in position while the mould is open. If cooling lines are present on slides, a DME slide retainer or Markdom approved equivalent shall be used for retention. Moulds with ejection elements below a slide will have positive early ejector returns to move the ejector plate to the retracted position before the slide is actuated. A micro/limit switch shall also be installed if early returns are used. To ensure machine safety signal upon return of the ejector plate, safety limit switches for ejector retract will be installed. Wiring to be properly secured or contained within the tooling. Wiring is to terminate into a liquids resistant electrical box mounted to the top of mould, with Hubbell HBL 7487N twist lock connectors mounted to the cover and identified with core pull type and number. Limit switches are to be buried below flush unless otherwise noted. Positive return MP compression springs at 37% maximum deflection are to be used to retract the ejector system. Safety limit switches of each moving function type will be installed and wired in series. Burgess switches are the type to be used for signalling open or pull position on slides and coring actions, style to suit application. DME Thin Switch brand high temperature switches are to be used for the signalling of ejector retract. MOULD BASE INFORMATION A standard D.M.E. No. 2 steel mould base, 4140 tool steel, or Markdom approved equivalent, must be used. All moulds must have four standard D.M.E. leader pins and bushings, or a Markdom approved equivalent. Any exception must be approved by Markdom. Leader pin bushings are to be vented to the outside of mould below the head at a size to allow for air escape and removal of foreign materials. In preventing the mould from being assembled backwards, offset one leader pin or use one leader pin larger in diameter than the other leader pins. If the supplier has obtained approval to use a mould base with two leader pins, one pin must be of a different diameter. Provide a minimum of two (2) pry bar relief slots for opening the mould at the parting line unless there is sufficient parting line relief to do so.

10 Page 10 of 22 MOULD BASE INFORMATION (cont d) Provide tapped holes on all four sides of each half of the mould (min) for handling purposes. The size of the handling holes is predicated on mould size and weight. Identify the mould base on the side with a Markdom approved tag that will be provided to you. You will also be asked to affix any customer specific markings when required. Standard D.M.E. die locks or Markdom approved equivalent, must be used on all moulds designed with a flat parting line, and wherever part complexity requires them to be used. All tools shall have a shot counter installed (Progressive Components is the preferred supplier). NOTE: A tooling retention strap is to be painted RED and installed on the operator side of the mould across the parting line. If more than one strap is required due to large mould size or multiple plate actions, retention straps are to be located cross corner (2), or all four corners (4), on both operator and non-operator sides of mould. *NOTE: Safety retention strap(s) must be positioned for unobstructed removal in the moulding machine (secondary mounting hole(s) below parting lines for on mould production mode storage of straps is preferred). CORES AND CAVITIES Make cores and cavities as follows: A) Large cores and cavities AISI Type: P-20 HH Pre-hardened tool steel with a through hardness of Rockwell C. AISI Type: H-13 tool steel with a through hardness of Rockwell C is preferred with inserted mould base for multi cavity applications. B) Small cores AISI Type: H-13 tool steel with a through hardness of Rockwell C. Any material substitution must be approved by Markdom. Steel certificates for all must be supplied with completed mould, forwarded to Markdom Engineering. Cores and cavities must have adequate cooling to ensure optimum production capability of the mould.

11 CORES AND CAVITIES (cont d) Page 11 of 22 Cores and cavities are to be designed with sufficient base size and fastening to ensure stability during the ejection cycle. Ejector pins are to be DME brand, and for round details or coining, standard DME CX core pins, or Markdom approved equivalent, are to be used whenever possible. All cores and cavities are to be individually inserted into the mould; multiple profiles will not be permitted unless otherwise approved by Markdom. Small standing steel and/or critical areas of the cores and cavities are to be individually inserted. A sub plate is to be used as a back up for small inserts. All irregular shaped core pins or ejector pins must be keyed to prevent rotation. All part surfaces are to be free of undercuts, including excess EDM finish, unless approved by Markdom. All final polishing is to be in the line of draw to allow maximum release of part. All cores and cavities must be properly vented to prevent gas entrapment and/or to ensure proper filling of the cavity. Final venting shall be done following the initial sampling of the tool. All cavities, in all tools that have the same part number, are to be made using the same machining set-ups regardless of the number of released tools ordered for capacity. Example: Two (2) - four (4) cavity moulds require an EDM blind hole to be placed in a location with a high degree of accuracy. All eight cavities shall be EDM d using the same machine, set-up aids and procedures consecutively. No welding allowed on any area of the mould unless authorized by Markdom prior to welding. Any weld that takes place must be in conformance to steel supplier specifications. i.e.: heating, relieving. Micro welding is not to be used where a texture has/will be presented. All moulds are to be of a balanced design, i.e. cavity/part orientation is to ensure that the gate location and size is identical from cavity to cavity.

12 CORES AND CAVITIES (cont d) Page 12 of 22 All parting lines that have been made via any other method than grinding, shall have at minimum one surface polished (min. requirement is equivalent of a 220 stone). All blocks shall have the steel type and the hardness value indicated on the block via engraving or hand stamped characters that are below flush. Locating ring is to be DME #6521 unless otherwise specified by Markdom. Sprue bushing is to be DME B series, R = 1/2 (O = 5/32 or size to suit application), located for anti-rotation, and back of head flush at bottom of locating ring bore unless otherwise specified for sprue length plastic material reduction. When numbering cavities, please number them from left to right, and top to bottom as read on the cavity side of the tool, which will become the 0 data point at cavity #1 corner. Example: Mould Identification A mould Property Identification Plaque will be affixed to the mould, preferably on the cavity half, in a location which is unobstructed by components or attachments. The following information will be engraved into the outside core side of the mould on the operator side: Mould Number (as it appears on the Purchase Order) Mould Size (in) Mould Weight (lbs) Steel Type (Cavity/Core) Maximum Ejector Stroke (in) Calendar and date wheels when required are to be DME - FYM type only with month on outer ring and year in center and positioned under part surface at a position and size specified by Markdom. An OEM (such as GM) trademark logo will appear to the left side of the part number identification on each part when specified by Markdom.

13 Page 13 of 22 SLIDES AND LIFTERS & MISCELLANEOUS HARDWARE Make slides and lifters as follows: A). Large slides AISI Type H-13 tool steel (through hardness Rockwell C 48-52) AISI Type P-20 HH Pre-hardened tool steel (through hardness Rockwell C 36-38) B). Small slides and lifters AISI Type H-13 tool steel (through hardness: Rockwell C 48-52) All slides must be equipped with a positive locking and locating device sufficient to eliminate movement during the injection and ejection cycle and to keep slides in position while the mould is open (includes retain hydraulic slides back at pull/open). Hardened steel heel blocks will be used if possible, and made as follows: AISI Type H-13 Tool steel (through hardness Rockwell C 48-52) Use standard H-13 nitrided wear plates or approved equivalent under all slides. To fabricate wear plates use the following material and heat-treat as specified. Use AISI Type H-13 tool steel (through hardness Rockwell C 48-52) for side gibs. A center key in addition to the side gibs, is to be used to guide all slides whenever the width of the slide exceeds the length. Always have one nitrided component. e.g. Nitrided slide and hardened wear plate, heel block and gibs, or hardened slide and nitrided heel blocks, wear plates and gibs. Gibs are to be doweled into position or held apart and in position by the wear plates. All slides/heel block combination shall have one wear plate installed using low head/full size socket head cap screws. If a slide contains inserts, they shall be dowelled into location and preferably contain a heel. All components shall have the steel type and the hardness value indicated on the block via engraving or hand stamped characters that are below flush. Wear plates and gibs must contain grease grooves.

14 Page 14 of 22 SLIDES AND LIFTERS & MISCELLANEOUS HARDWARE (cont d) Grease fittings are required to ensure adequate lubrication if required. Slides if of sufficient size shall have cooling. Large slides must have adequate cooling to ensure optimum production capability of the mould. Other slides are to be judged on an as needed basis. If cooling circuits are present, then a DME slide retainer or Markdom approved equivalent shall be used. All slides should be mechanically actuated. Hydraulic actuation is to be used only with the approval of Markdom. Horn pins must be standard D.M.E. or Markdom approved equivalent and must not be greater in length than the guide pins. All limit switch terminals must be identified and made of oil and solvent resistant materials and be wired ready for use and clearly marked.

15 Page 15 of 22 RUNNER SYSTEM All runner systems must be balanced unless otherwise instructed by Markdom. The runner system must minimize material usage while still using acceptable moulding practices. Runners must be full round. Trapezoidal runners can be used only with approval of Markdom. No other runner cross sections will be acceptable. Provide a cold slug well for the sprue and at the end of the runner. Runners will be provided with adequate ejection for proper removal from the mould. Runners and gates shall be polished, blended and all sharp corners and transitions shall have radii. A sprue puller will be used to ensure removal of the sprue from the sprue bushing. A standard D.M.E. sprue bushing or Markdom approved equivalent must be used. When the mould is closed the runner bars should have 0.05 mm separation to allow venting of gas and/or adequately vented at the ends, with a 2 mm land length. Hardened runner bars must be used in all mould construction. Made from AISI Type H- 13 (through hardness Rockwell C 48-52) Runner shutoffs are to be designed so that they are replaceable or indexed, and accessible without tool disassembly. Shutoffs by welded sections are not permitted unless agreed to by Markdom. High volume multi-cavity moulds with intricate cores should be designed with runner shutoffs. The runner system should have a separate cooling circuit whenever possible. Runner/sprue volume is to be provided as a percentage of the shot weight and is to be shown on the drawing and shall be shown as regrind percentage.

16 Page 16 of 22 PART AND RUNNER DISPOSAL All cavities should be sub-gated whenever the part design will permit in order to facilitate part and runner separation. All parts and runner systems must fall freely from the mould to facilitate continuous operation of the mould. Any mould that, because of part design, cannot be designed to run automatically must be reviewed prior and approved by Markdom. All tools shall have a clean out slot provided on the parallels to allow for runner and part escapement (in conjunction with air escape vents - refer to mould base information section). HOT RUNNER SYSTEMS Yudo hot runner systems are the preferred choice. All hot runner tools shall have insulating plates both top and bottom unless directed otherwise. Check machine specifications for magnetic platens which do not require insulator plates. All mould heater and thermocouple wiring is to be properly mounted and secured within the mould. A wiring diagram including an isometric operator perspective view of the system with all zones identified and top of mould reference note is to be provided with all tools having a hot runner system. All tooling having a hot runner system shall come equipped with the applicable power input and thermocouple connector and mounting box. Please ensure that these items are included in all final drawings provided to us. All tooling is to be received pre-wired and ready for plug in and immediate use. Single zone power and thermocouple input connectors are to be the same as for multi zone applications: DME # PIC-8-G and MTC-8-G or Markdom approved equivalent. Pneumatic SVG connection will be a Parker hose mounted crimp swivel to mate with Parker male adapter on the moulding machine. If the system requires more than a single zone, the unit shall come equipped with an eight (16) pin power connector, DME # PIC-8-G or Markdom approved equivalent and an eight (16) pin thermocouple connector, DME # MTC-8-G or Markdom approved equivalent.

17 Page 17 of 22 HOT RUNNER SYSTEMS (cont d) Drop zones will be identified by associated cavity number and will be first in the numbering order, followed next by manifold inlet seat zone(s) and last to be the remaining manifold zones. Power connector pins will be wired as follows: Zone 1 = Pins 1+2, Zone 2 = Pins Zone 8 = Pins 7+8 Thermocouple connector pins will be wired as follows: Zone 1 = Pins 1+9, Zone 2 = Pins 2+10 Zone 8 = Pins 8+16 EJECTION SYSTEM Ejector pins must be D.M.E. standard or Markdom approved equivalent, (hot work type). Ejector pins must be flush to below flush to a maximum of 0.2 mm unless noted otherwise. The ejector plate assembly must have standard D.M.E. stop pins, or Markdom approved equivalent to ensure minimum deflection during the injection cycle. Stop buttons are to be installed on the ejector back plate and not on the mould base backup plate/assembly. Guide pins and bushings must be used to ensure continued alignment of the ejector assembly. Graphite impregnated bushings are the preferred choice. Ejection is required under all runners. All moulds must have ejector return springs. Moulds with ejection elements under a slide will have positive early ejector returns, to move the ejector plate to the retracted position before the slide is actuated, and it shall include limit switches on the ejector plate. All moulds shall use positive ejection, and positive ejection return pins are to be present on all moulds. All moulds shall have a polycarbonate cover over the ejector box on the top of the mould to prevent debris from entering into the ejection system.

18 Page 18 of 22 COOLING SYSTEM Cooling lines must be dimensionally located on the design drawings. Cooling inlets and outlets must be stamped with numbers for different zones. Example: 1 in 1 out, 2 in 2 out, etc. Locate all in and out cooling lines on the non-operator sides of the tool whenever possible. Cooling lines must never exit in the clamp slots of the mould. Cooling lines should not exit at the top of the tool unless necessary and agreed to prior by Markdom. Standard D.M.E. quick-disconnect cooling fittings, or Markdom approved equivalent, must be used on all cooling lines unless they are intended for use with an oil thermolator, whereupon the correct fittings must be used. All cooling fittings must be located at 3.0 mm minimum below the surface of the mould to prevent damage. Markdom is to be advised of any deviations. Maximum cooling must be provided within the tool. Looping of cooling lines between cavities is not desired, circuits should be separate. All cooling lines must be designed to provide for proper turbulent flow of cooling through the mould. All cooling line quick-connect fittings and related piping will be permanent parts of the tool. Use ¼ NPT fittings at minimum DME or Markdom approved equivalent. Do not use smaller fitting sizes unless you have received approval from Markdom. The preferred connector style is: Jiffy 352 series. In multiple cavity applications, the use of O rings to join lines should be avoided unless absolutely necessary. Hard piping to the outside of retainers is preferred.

19 Page 19 of 22 COOLING SYSTEM (cont d) When specified by Markdom to use a water manifold quick change system: 12 Couplings (6 Circuits) Use Staubli PN: RMI with RMI 09 NPT plugs on the mould. Also supply RMI /JV mobile plate for machine side with RMI 09 NPT sockets for 3/8 hose inside diameter. 20 Couplings (10 Circuits) Use Staubli PN: RMI with RMI 09 NPT plugs on the mould. Also supply RMI /JV mobile plate for machine side with RMI 09 NPT sockets for 3/8 hose inside diameter (1/2 hose diameter may be required for some large tool applications Markdom to specify). *Water inlets and outlets are to be mounted banked separated with inlets on left side and outlets on right side of center on the couplings plates. *Smaller tools use 12 couplings (6 circuits) and for larger tool use 20 couplings (10 circuits). Each tool must have two units one for core side and one for the cavity side. HYDRAULIC CYLINDERS AND SYSTEMS Hydraulic actuators (cylinders) are to be Miller H series or Parker 2H series with NPT port threads unless otherwise specified by Markdom. Flow dividers and controls type and requirement will be approved by Markdom for special applications such as large mould ejector systems or other multiple cylinder applications. Quick connect fittings are to be Parker H2-62 for set mode and H2-63 for pull mode. A core pull sequence plaque will appear on the operator side of the mould and will illustrate the sequence of operations for one full cycle mould open to close and inject. Hydraulic hose will be Parker # 451 TC PSI (-4 or -8 size if required for specific application). Multiple same action/function cylinders on cavity or core half will be hosed equally from each side of center of mould into a main manifold block attached on the non-operator side at or close to the center of each half. Quick connectors on manifolds will allow the mould to clear the machine tie bars by ½ minimum at both operator and non-operator sides when the mould is set into the machine (below flush to outside of mould inclusive of quick connect fittings preferred where possible).

20 Page 20 of 22 HYDRAULIC CYLINDERS AND SYSTEMS (cont d) Internal hydraulic inlet and transfer lines through the cavity/core/ejector rails/plates are preferred when steel conditions allow. Manifolds or direct internal inlets are to be identified with ejector pull or core pulls number and PULL or SET for each.
