Custom Plastic Injection Molding Manufacturer in China

A full-service plastic injection molding manufacturer in China such as PlasticMolder provides DFM analysis, mold design and manufacturing, serial production, insert and overmolding, secondary operations, and quality inspection. We support projects from prototype through high-volume production under one roof in Dongguan.

We process commodity and engineering thermoplastics including ABS, PC, PP, PA6, PA66, POM, and TPU, as well as glass-filled and flame-retardant grades. Material selection is matched to your mechanical, thermal, and regulatory requirements.

We support low-volume injection molding from a few hundred parts using soft-tooling and bridge production, all the way to multi-cavity high-volume runs. Prototype tooling lets you validate form, fit, and function before committing to hardened steel production molds.

Yes. Our in-house tool room designs and builds injection molds, including multi-cavity, hot-runner, insert, and overmolding tools. In-house mold manufacturing shortens lead times and gives us full control over dimensional accuracy and maintenance.

We serve automotive, medical, electronics, EV and energy storage, and general industrial markets. Each segment is supported with the relevant material traceability, tolerances, and quality documentation it requires.

Quality control combines incoming material verification, in-process SPC, first-article inspection, and final dimensional reporting. Our manufacturing system is built around repeatable processes, calibrated metrology, and continuous improvement.
