WHY？
Why Choose Chieh Cheng?
#01Tooling Expertise & Existing Mold Library
10,000+ Development Projects
1,000+ Company-Owned Molds
With 30+ years of rubber and silicone manufacturing experience, we have completed more than 10,000 tooling and product development projects across diverse sizes, structures, materials, and applications.
We also maintain 1,000+ company-owned molds available for customer use. For suitable components, existing tooling may eliminate the need for new mold investment — helping reduce upfront costs and shorten development lead times.
When existing tooling does not meet your requirements, our in-house tooling team can develop custom molds based on your drawings, samples, or application specifications.
Existing Tooling Includes
- O-Rings · Gaskets · Waterproof Seals · Sealing Strips · Other Rubber & Silicone Components
#02DFM & In-House Engineering
With our in-house mold design and engineering team, Chieh Cheng supports customers from the early stages of product development through DFM (Design for Manufacturability) evaluation. We assess material selection, product structure, tooling, manufacturing processes, and cost considerations before production begins.
By integrating product development, tooling, trial production, validation, and manufacturing under one team, we help reduce design iterations, improve communication efficiency, and shorten the path from concept to mass production.
Designed for Manufacturability. Engineered for Production.
