Need a square flange housing with a bore configuration that is not a standard part? Dongguan Changxinda Precision Technology Co., Ltd. machines fully custom, non-standard housings to your drawing or 3D model — any number of bore steps, any fit, any slot. 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 bore steps, fit classes, depths, slots, flange and material; we return a manufacturability review and a quote, then machine, inspect and ship. Critical features — step diameters, fit clearance and concentricity — 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:
- Send drawings: 2D PDF, STEP, IGES or SolidWorks — or a physical sample to reverse-engineer.
- DFM review: engineering feedback on step sequence, fit class, slot geometry and cost before you commit.
- Quote in 24h: transparent pricing by drawing and quantity, no tooling charge.
- Program & gauges: dedicated turn-mill CAM, boring bars and plug gauges for your step sizes.
- CNC machining: multi-step boring, slot milling and flange turning to ±0.01 mm.
- Finish & inspect: anodizing, polishing or coating, then CMM dimensional report.
- Ship: protected export packing to your schedule.
Non-standard is our normal work. Bore chains with five or more steps, mixed fit classes in one body, small-entry deep bores, internal grooves and cross-slots — all machined to print.
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.

Yes — that is our core work. Send a 2D drawing, STEP/IGES/SolidWorks model or a physical sample and we machine the custom step sequence, fits and slots 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.
Yes — send a sample and we measure each bore step and fit, then quote a drop-in equivalent with a full CMM report and gauge verification.
Plug gauges for each step during production, plus CMM measurement of diameters, depths and concentricity in the final report — so the fits are proven, not assumed.
