Precision Plastic Mold Making
The mold is the mother of the part. We build high-quality molds for over a million cycles, especially for medical and electronics. Using mold flow analysis, conformal cooling, and premium steels, we ensure stable, efficient production of perfect parts.
Why LEDA for Plastic Mold Making?
√Built for High-Precision Products – We focus on manufacturing ultra-high-precision, long-life injection molds required by the medical, optical, and electronics industries.
√Combination of Science and Experience – We use mold flow analysis to guide design and employ techniques like hardened steels and conformal cooling to enhance mold performance and production efficiency.
√Ensures Production Stability – A superior mold is the foundation of consistent quality. The molds we deliver are a reliable guarantee for your mass production success.

Core Capabilities
High-Cavity, Long-Life Mold Design & Build
Specializes in molds with over 1 million shot life, using high-hardness, high-polishability steels.
Mold Flow Analysis & Thermal Management
