Plastic Injection Molding

Plastic injection molding provides high-volume production of consistent, durable parts with excellent repeatability. The process enables complex geometries and thin-walled designs while maintaining tight tolerances (±0.1mm). With fast cycle times and low per-unit costs, it's ideal for mass production across industries like automotive, consumer goods, and medical devices.
