Custom Cavity Housings — NDA Protected, Built to Drawing. Need a connector housing with a specific internal cavity that is not a catalogue part? Dongguan Changxinda Precision Technology Co., Ltd. machines fully custom, non-standard housings to your drawing or 3D model — any step sequence, any depth, any thread. Since 2008 the factory has built one-off prototypes and scheduled production batches for 200+ customers across ten industries, exporting 50–60% of its output overseas.
We are build-to-print: you define the cavity geometry, thread standard, locating holes and material; we return a manufacturability review and a quote, then machine, inspect and ship. Critical features — cavity diameters, shoulder depths and wall thickness — are held to ±0.01 mm and verified on a CMM, whether you order one prototype or a recurring batch.
Custom does not mean uncertain. Our workflow keeps you in control from drawing to delivery:
- 1Send drawings: 2D PDF, STEP, IGES or SolidWorks — or a physical sample to reverse-engineer.
- 2DFM review: engineering feedback on cavity steps, wall thickness, threads and cost before you commit.
- 3Quote in 24h: transparent pricing by drawing and quantity, no tooling charge.
- 4Program & fixture: dedicated turn-mill CAM and fixtures for your housing.
- 5CNC machining: boring, turning and threading to ±0.01 mm on critical features.
- 6Finish & inspect: anodizing, polishing or coating, then CMM dimensional report.
- 7Ship: protected export packing to your schedule.
Non-standard is our normal work. Custom cavity profiles, stepped bores, internal thread combinations, cross-holes and mounting flanges — all machined to print. Critical cavity diameters, shoulder depths and wall thickness are held to ±0.01 mm and verified on a CMM.
Confidentiality is a condition of the job, not an add-on. We sign an NDA before engineering review, limit drawing access to the assigned programming and machining team, keep your fixtures and programs dedicated to your program, and scrap surplus or reject parts on request. You keep the IP; we keep it that way.
Changxinda is a 2008-established CNC factory with 90+ staff, multiple turn-mill lathes and 4-axis / 5-axis machining centers backed by a dedicated QC lab. Capacity is planned per program, supporting stable scheduled batches for repeat orders.

Yes — that is our core work. Send a 2D drawing, STEP/IGES/SolidWorks model or a physical sample and we machine the custom cavity steps, threads and holes to print.
Yes, routinely. Drawings are limited to the assigned programming and machining team, fixtures and programs stay dedicated to your part, and surplus or reject parts are scrapped on request.
One piece. There is no tooling or setup charge, so single prototypes are practical and mass production runs on the same inspection standard.
Capacity is planned per program. Prototypes ship in 3–7 days, small batches in 7–14 days and production volumes in 14–30 days, with supply ability up to 10,000 pieces per month.
Aluminum, stainless steel, brass and titanium with black or clear anodizing, polishing or custom coatings — matched to your pressure and temperature requirements.
CMM probing of each step diameter and shoulder depth, wall-thickness checks and cross-hole position, with a full dimensional report and first-article inspection on new programs.
