die casting molds Molds & technologies
Company Introduction In last few decades, die casting has been instrumental in reducing the weight of an automobile contributing to fuel efficiency and lighter products. Innovative techniques in mold making & newer technologies have helped die casters cast complex parts with consistent quality. With over two decades experience, Raga has been innovating to provide this value to a die casting company globally. Raga assists you to develop molds & its trial castings in the fastest turnaround time for HPDC machines upto 2500 tons. Molds are Made in Taiwan, one of the best mold making countries in the world. Raga has partnered with mold makers having over 30 years experience. The molds are built with application of latest technologies like Squeeze, Jet Cooling, Vacuum, Thermoregulation and Newage Coatings/heat treatment/nitriding processes. Molds are supplied with guaranteed service life with spares available locally in India. Raga Technologies Taiwan Co. Ltd (Raga-Taiwan) is a Raga group company located in Taichung city, Taiwan. It works in close coordination with the Raga team in India and mold makers in Taiwan to provide the best of services to the Indian customers. key challenges for a die caster Ÿ Un reliability of mold deliveries Ÿ Longer turnaround time for developments Ÿ Higher rejection levels Ÿ Complexities in parts Ÿ Life of mold and its consumables Ÿ Absence of local support for imported molds whytaiwan?

technologies to take care of complexities Jet cooling Vacuum System Lets look at some case studies Case Study - I Product Name Tonnage Problem Solution Result Cam Carrier & Bed Plate 1650T Soldering and porosity issue. Designing of mold with jet cooling and vacuum technology Rejection rate came down from 5% to 4% Bed Plate Cam Carrier
Case Study - II Product Name Tonnage Problem Solution Result Crank Case 650T Space constraint, Ejection issue Better design concept Made feasible with compact design & solving of ejection issue Case Study - III Product Name Tonnage Problem Solution Result Extension Housing 800T & 1250T Space constraint issue Advanced design concept Made possible of Non return valve in limited space Case Study - IV Product Name Tonnage Problem Solution Result Intake Manifold 500T Shrinkage Porosity & Flatness issue Advanced design concept with Jet cooling and slide within slide. Minimizing of shrinkage and flatness issue within tolerance. Case Study - V Product Name Tonnage Problem Solution Result PV Housing 800T Feasibility, Ejection & porosity issue. Advanced design concept with technology by using- Angular pin (to unload slide before hydraulic movement), Iron insert for undercut profile, Squeeze pin, Tunnel core, Chill-vent with vacuum. Made feasible, issue is minimized.
