Radiant specializes in molding precision gears in high performance engineering plastics. Our team has over 20 + years of experience in plastic gear tooling & processing technology.
 Getting the plastic gear profile right requires an intricate understanding of shrinkage patterns and this needs to be compensated in the tool design. Gears are molded in various grades of Polyacetals and Polyamides with fillers like Glass fibre, PTFE and Carbon, depending on the nature of application.
 At Radiant, we understand the importance of various ingredients for consistent & repeatable gear molding - precision equipment, optimized pressure curves, predetermined constant temperature and clean environment. The state of the art closed loop control and real-time process monitoring eliminates any chance of human error.

With the rapid strides in technology, we have been witnessing higher levels of integration in components & technologies in a cost effective and scalable manner. Insert molding is one way of achieving this. It requires a high degree of accuracy in tool making and very precise process control. We have special purpose vertical molding machines to cut down on cycle times and boost productivity for insert molded components.

Over molding involves encapsulating a plastic component with another polymer that is molded at a lower temperature. This is followed wherever superior properties are required but at only specific areas. Given that this could only be fulfilled by using a more expensive polymer, cost could be cut down by over molding such a polymer on a plastic component molded out of less expensive material. Other applications are in components wherein an elastomer needs to be over molded for leak tightness. or even in decorative applications for good aesthetics. Radiant produces over molded components for both automotive technical & decorative applications.

New product development especially for automotive industries is focused on smaller and lighter products, requiring thinner wall sections in components, housings and covers. At Radiant, we have an integrated approach for designing, tooling and manufacturing thin wall injection molded parts. We have expertise in special processing and tooting requirements: higher pressures and speeds, faster cooling times and special design considerations wrt part-ejection and gating arrangements to mold wall sections as thin as 0.3 mm in polymers with up to 30% glass fibre content.

Light Weighting, Cost Reduction, Evolving Emission Norms and Increasing Integration are key drivers that are necessitating a shift to plastic based components in vehicles today. Some of the applications for which Radiant has developed plastic components are in Oil Pumps, Thermostats, Intercoolers, Engine Mounts, Gears and Engine Cooling Modules. In addition to light weighting & increased durability, plastic components can be integrated with other components in the molding process itself. Radiant has partnerships with its key supplier-partners to re-engineer our customer's metal parts into engineering plastics through finite element analysis & simulation.
 

Development and supply of safety critical components is a challenge that Radiant always likes to take on, for this is what clearly differentiates us from our competitors in the industry. Over the last 20 years, Radiant has an enviable track record in such successful developments. Typically such parts not only to have qualify multiple close-tolerance dimensions on the drawing in regular production but also undergo validation or endurance testing under various load and environmental conditions. It is here that our know-how of critical success factors - too design, shrinkages, process control & error proofing techniques differentiates us from the rest.
 Applications for such parts are in Fuel Delivery Systems, Fuel Tanks, Transmission Systems, Under the Bonnet Components, Collapsible Steering Systems, Head Lighting Systems and Accelerator Pedal Modules. As an example, Radiant has never faced a single warranty claim from one of our Japanese OEMs to whom we supply such parts over last 12 years. In another application for Fuel Systems, Radiant is only the 3rd global supplierand the 1st supplier outside of Europe\USA to be nominated for supplies of critical components for a Toyota application.
