Automotive Injection Molding Experts


The automotive industry is one of the most advanced manufacturing sectors in the United States today. Reliance on injection molded plastic parts to improve safety, increase fuel efficiency, use alternative fuels, and reduce environmental impact continues to rise and evolve in dynamic new directions.

That’s why engineers from major automotive OEMs turn to Kaysun to solve their toughest design challenges—material selection and performance, design for manufacturability, prototyping, tool design, tolerance, quality control, and more.


These resources illustrate how an injection molder relationship is key to identifying and correcting defects before there are costly consequences:

Metal-to-Plastic Conversion Expertise for Quality, High-Performance Outcomes


In light of stricter federal and environmental regulations, automotive OEMs are embracing metal-to-plastic conversion as a proven solution for reducing vehicle weight and increasing fuel efficiency. Replacing heavy metal parts with identical but lighter-weight injection molded plastic components that are just as durable helps meet fuel efficiency goals, emission requirements and operational cost reductions.

Partners in Automotive Part Design and Material Selection: Kaysun’s Added Value


The demands placed on injection molded plastic parts within automotive applications are great. Designs are increasingly complex and sometimes require tolerances as tight as .001 inches. Harsh under-the-hood operating environments present extremes in temperatures, chemical exposure, and performance requirements. Designs and materials must stand up to the test.

Currently, there are more than 25,000 resins engineered to provide specific physical characteristics such as strength, flexibility, temperature, corrosion, and UV resistance. As material science and injection molding experts, Kaysun engineers share their in-depth knowledge to help automotive OEMs select the best plastic for performance and budgetary goals. This is apparent when designing and manufacturing complex parts and components for vehicle braking systems, cooling systems, fuel delivery systems, and the powertrain.
