Need a large flange connector housing 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 flange size, hole pattern, thread or spline. 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 flange geometry, mount pattern, thread, spline and material; we return a manufacturability review and a quote, then machine, inspect and ship. Critical features — flange flatness, hole spacing and thread position — 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 flange stiffness, hole pattern, thread and cost before you commit.
- Quote in 24h: transparent pricing by drawing and quantity, no tooling charge.
- Program & fixture: dedicated turn-mill CAM and supporting fixtures for your housing.
- CNC machining: turning, flange milling and drilling to ±0.01 mm on critical features.
- Finish & inspect: anodizing, polishing or coating, then CMM dimensional report.
- Ship: protected export packing to your schedule.
Non-standard is our normal work. Oversized flanges, non-symmetric hole patterns, recessed seats, combined thread and spline interfaces, and thin-wall sections — 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 flange, holes and thread 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 or drawing and we reverse-engineer the flange, hole pattern and thread, then quote a drop-in equivalent with a full CMM report.
CMM probing of flatness across the mount face, hole spacing and diagonal, plus thread and bore concentricity, with a full dimensional report and first-article inspection on new programs.
