Overview Description

With over 35 years of experience in plastic mold development, Polygon provides highly competitive manufacturing solutions for global leading customers in the automotive electronics, data communication & storage, medical, sensor, optical, and smart electronics industries — including but not limited to product design support, plastic mold and stamping die design, fabrication, and components production.

35+ years experience: 10K+ sets high precision injection molds

High Precision Injection Mold Development

Experienced designers use Pro/E and Creo software for mold design. At the early stage of the project, a feasibility study will be conducted based on customer requirements, followed by a professional DFM analysis supported by our extensive experience and mold flow simulation. These efforts help reduce production risks, enhance production and quality stability, lower costs, and improve customer competitiveness.
