A time-tested, holistic approach to reliable success

Utilizing our comprehensive approach — early design involvement (prototypes and finite element and mold flow analyses), design for manufacturability studies, careful material selection and testing, and a customized injection-molding process with comprehensive quality control — we make components our customers can rely on performing in extreme — even life or death — applications.

When it is time for production, we provide a full range of precision injection molding technologies, including insert, two-shot and overmolding, utilizing state-of-the-art equipment in the hands of a highly experienced and dedicated workforce. Our quality performance is ensured with robust inspection, including optical, laser, contact, and in-house mechanical testing. We provide Secondary Operations, including plastic part machining, ultrasonic welding, potting/sealing, heat staking, and manual and automated assembly.

And with rapid advances in technology that give manufacturers design possibilities that didn’t exist a few years ago, products can be smaller and more complex while offering increased functionality, performance, and durability. With our deep expertise in tighter tolerances, geometries and materials, Kaysun helps client design teams select the right materials and processes with the best physical properties for achieving optimal performance goals.
