Changzhou Heiyaoshi Auto Parts Co., Ltd

BMW-focused modified parts manufacturer · Changzhou, China

We design and build modified parts for BMW in our own facility — tooling, injection molding, finishing, and inspection under one roof. Because the molds are ours and the presses are ours, nothing queues behind a third party and nothing gets lost between suppliers.

From Mold to Finished Part

30,000 m² facility · In-house tooling · 100% virgin material · OEM & ODM · BMW-focused catalog

In-House Workshop

Tooling, injection molding, and finishing — 30,000 m² under one roof, on our own schedule.

OEM/ODM

Samples, drawings, or 3D data in. DFM review, mold design, trial samples, and mass production out.

Quality Assurance

Virgin material verified on arrival, first articles measured, in-process and pre-shipment checks before anything ships.
