Invision Product Data and Care Instructions

Transcription

1 Invision Product Data and Care Instructions General Information Invision sheets are innovative design elements, made in Germany. Fabrics, metals or organic materials such as grass, leaves or flowers are embedded in polyester (PETG) by means of an especially developed and licensed process. advantages of Invision applications of Invision the sheets can be easily and rapidly thermoformed at low energy consumption without predrying white retaining their frosted surface good impact strength available in thicknesses from 3 to 24 mm other colours and measurements on demand also available with UV protection suitable for outdoor usage (with UV protection), highly weatherproof food proof except for the version with UV protection exclusive appearance applications: interior design: partition walls, furniture, walland counter coverings, light elements etc. hotels, trade, industry, offices etc. booth building: walls, ceilings, floorings, bars, colums etc. shop-fitting: system concepts and individual solutions POS for outdoor and indoor usage displays kitchen backwalls lamp covers advertising pillars doors, partitions / sliding doors sculptures shower cabins Storage Store Invision sheets in horizontal position on a flat surface and provide adequate support to avoid deformation of the product. It is recommended not to remove the protective film prior to installation. The panels are best stored at room temperature. Avoid exposure to direct sunlight, extreme temperatures and chemical vapours

2 OUTDOOR USAGE If using Invision sheets for outdoor applications we recommend the version with UV protection to prevent the yellowing of the PETG panel. In spite of UV protection changes in colour of organic inlays may occur. The edges of the panels have to be sealed so that no water or moisture can get into the inside of the sheets. USAGE IN WET OR HUMID SURROUNDINGS Certain inlays for Invision like organic materials, but also papers and fabrics can have the tendency to absorb moisture over time if submerged in water or exposed to high humidity if they are not adequately sealed. These types of Invision should not be immerged in water without first applying an approved edge sealing treatment. This is also applicable for the edges of holes drilled into Invision sheets. glow wire flammability index, IEC , in C (*) 0,5 0,75 1 1,5 2 2,5 3 4 Invision

4 Cleaning and Care Invision has a pore-free surface to which it is difficult for dirt to adhere. Dusty parts can be wiped with water, a soft cloth or a sponge but should never be rubbed when dry! For thorough cleaning, we recommend a non-abrasive detergent. Razor blades or other sharp tools, abrasive or strongly alkaline detergents, solvents, leaded benzene and carbon tetrachloride should not be used. The only way to achieve effective cleaning without streaks is to use a microfiber cloth that is simply dampened with water. In the case of a greater build-up of dirt or greasy stains in particular, benzenefree pure petroleum spirit (cleaner`s naphtha or light gasoline) may be applied. Splashes of dye, grease or residual sealing putting etc. may be removed using a soft cloth soaked in ethyl alcohol, isopropyl alcohol or petroleum ether (boiling point 65 C) and gentle rubbing prior to curing. Rust marks can be removed with a 10% solution of oxalic acid. ATTENTION! Do not use steam cleaners. Never expose Invision sheets to temperatures above 65 C. Invision sheets without UV protection should not be exposed to direct sunlight for an extended period of time. UV light can cause changes of the embedded materials. Do not expose Invision to splash water or standing water if the cutting edges and drill holes were not sealed. Inlays made of organic materials, paper or textiles tend to absorb water through the panels' open edges

5 Processing Instructions GENERAL REMARKS: - tools Invision sheets can be machined using the standard tools commonly used for metal and woodworking. We recommend carbide-tipped tools. Above all, it is important to use sharp cutting tools with the right geometry. - cooling No cooling is required during the normal machining of our Invision sheets. In the event of local overheating during machining e.g. when drilling through very thick materials we recommend cooling with water or oilfree compressed air. - dimensional accuracy The coefficient of linear expansion of Invision at mm/mk, is significantly higher than for metal or glass. For this reason, dimensions should always be checked at room temperature. - protective foils Our standard-protection foils are not suitable for exposure to thermal loads and do not allow thermoforming. The foil should therefore be removed from the sheets before processes such as drying, hot line bending and/or thermoforming. - marking Marking out drill holes, cut edges etc. should be done on the protective foil. If marking is required, use a soft pencil or felt-tip pen. Marking tools should not be used as the tracing mark has a notching effect, and a higher load at this point may cause the sheet to crack

6 Bonding: In principle gluing must be performed with great care, and the choise of a suitable adhesive is of highest importance for a perfect result. Successfully we tested the following products, you can purchase them at specialiced dealers in a short time. We point out that gluings must be accomplished directly on PETG. We do not recommend an application of the adhesive on mounted foils, varnish, digital print, silkscreen print, or the like.

8 SAWING - hand saws Standard hand saws may be used to cut sheets. A saw with fine spacing between the teeth should be used. - circular saw Using a circular saw is the easiest way to cut Invision sheets. Experience has shown that carbidetipped circular saw blades produce the cleanest cuts. The spacing varies from fine for thin sheets to coarse for thicker materials. Ensure that no shavings are left on the cutting surface as these could damage the protective foil and scratch the sheets. - ribbon saw Ribbon saws are ideal for curved cutting or formed parts of irregular shapes. To achieve a clean cut edge it is important to work on a solid cutting surface. A wide spacing is required when working with thick materials. For higher quality cut edges, circular saws or milling cutters achieve a better result than ribbon saws. - trouble-shooting: fused cut edge: check tool sharpness check cutting speed and reduce if necessary check rate of advance and reduce if necessary cool if necessary notched cut edge: check tool sharpness check tool geometry improve cutting surface (use an underlay if necessary) - 8 -

9 DRILLING Standard drills used for metalworking are perfectly suitable for machining Invision sheets. Make sure that the cutters on the drill are sharp. Cooling during drilling is generally not necessary. When working with relatively large drilling depths we recommend using compressed air and/or regularly withdrawing the drill from the hole to reduce heat and remove shavings. Oil/water emulsions or cutting oils should not be used when drilling through Invision sheets. Standard circle-cutting equipment (e.g. circle cutters or compass saws) is suitable for large-scale drilling. The drill holes should be smooth and as free as possible of notches or rough areas to ensure secure fastening. recommended angles for drilling: point angleϕ Helix angle β cutting speed feed m/min. 0,1-0,3 mm/u The distance between whole and sheet edge should be at least 1.5 times of the diameter of the whole. MILLING Invision sheets are easy to process using milling machines. The choice of milling machine depends on the type of machining required. Some of the Invision sheets with special inlays e.g. metal structures can only be cut by water jet. Please ensure that your tool has good chip clearance and sharp cutters

10 SURFACE TREATMENT - flame polishing Propane, butane or other types of gas burner may be used for flame polishing. This technique can produce excellent results but requires experience and ongoing practice. Make sure that the material does not crystallize. Cracks may appear in the polished area in the long term. - polishing Medium-density riding polishing wheels with a peripheral velocity of 20 to 30 m/s can be used to polish Invision sheets with alkali-free polishing pastes. A clean polishing wheel without polishing paste in then used to complete the polishing process. Large-surface polishing should be avoided. - decorating Before treating polish Invision sheets e.g. by coating, screen printing or thermoforming recommend removing any loose particles of dirt or dust adhering to the surface using ionized air. The matt side of Invision sheets is not suitable for printing. - transfer printing Sheets and finished parts can be printed using transfer printing. - screen printing Invision sheets may be printed with standard screen printing equipment and inks suitable for thermoplastic polyesters (PET). The ink manufacturer`s recommendations should be followed. Invision sheets can be printed with UV-curved inks. The short-term UV radiation has not impact on the physical properties. The maximum application temperature of 65 C should not be exceeded during the drying process. - coating Once cleaned, Invision sheets may be coated without any other pre-treatment. Care should be taken to ensure that the coatings and printing inks are chemically compatible with Invision

11 FORMING - thermoforming Attention: not all inlays for Invision can be thermoformed! Protective foil: Our standard protective foils are not suitable for exposure to thermal loads, and do not allow thermoforming. The foil should be removed from the sheets before processes such as drying, hot line bending and/or thermoforming. - pre-drying Invision sheets do not have to be pre-dried. - hot line bending Hot folding is a relatively easy forming process for the production of uniaxially formed parts. Invision sheets simply require local heating to approximately 100 C. The Invision sheets are heated in a linear manner. As soon as the ideal temperature is reached, the sheet is removed from the heating element, folded, placed in the mold and clamped into position. The desired shape should be fixed until the material rigidifies. If using one-sided heating, the Invision sheets must be turned over several times to guarantee even heating on both sides. With sheet thicknesses of 2 mm or more and when producing large numbers of units, we recommend simultaneous heating appliance. By adjusting the heating width using the shields, various different bending radii can be achieved, although a minimum bending radius of 3 times the sheet thickness should not be undershot. When constructing forming molds, allowance should be made for shrinkage of 0.4%. Special materials are available for producing porous forming tools without vents. - male and female tools: The decision on whether to use a male or female tool depends on the application. To achieve a better surface quality on the outer side of the finished part, use of a female tool is recommended to attain greater detail

12 - free blowing or free drawing This technique is used to form domes. Blowing without a countermold involves working with air pressure, whilst the thermoforming process without a countermold is carried out in a vacuum. molding temperature Invision: C For questions, please contact: Designpanel GmbH Dagobertstraße Nürnberg Germany Phone: info@designpanel.de
