Beijing Jiacheng Technology Co., Ltd (Beijing JCEN) is a professional custom metal fabrication manufacturer based in Beijing, China, serving global clients since 1997.
We specialize in a complete range of custom metal fabrication services, including sheet metal stamping, deep drawing, CNC bending, laser cutting, riveting, TIG/MIG welding, and precision CNC machining. Our 100,000+ m² manufacturing facility is ISO 9001 certified, staffed by 85 experienced engineers and technicians with 30+ years of collective expertise in precision metal parts production.
From rapid prototyping to full-scale mass production, we deliver factory-direct pricing, tolerances as tight as ±0.005mm, 7-day sample lead times, and no minimum order quantity. Beijing JCEN is the trusted metal fabrication partner for OEMs across automotive, medical, aerospace, electronics, and industrial machinery industries in North America, Europe, and Asia.


Final process limits and tolerances depend on the material grade, thickness, geometry, tooling and inspection requirements. Mark critical features and datums on the drawing so they can be reviewed before quotation.
| Process | Engineering Review Focus |
|---|---|
| Laser Cutting | Material, thickness, edge condition and downstream forming |
| CNC Bending | Radius, bend allowance, flange length and sequence |
| Metal Stamping | Tooling route, volume and critical dimensions |
| Deep Drawing | Draw ratio, formability, radii and stage count |
| Welding | Joint design, distortion control, fixture and inspection |
| CNC Machining | Datum strategy, local tolerance and measurement |
Material choice affects forming, welding, corrosion resistance, appearance and total cost. The exact grade and finish are confirmed against the drawing.

Powder coating, anodizing, plating, passivation, brushing and polishing selected around function and appearance.
Review finishes →
Validate geometry and assembly first, then carry the approved drawing and process route into repeat production.
Explore prototyping →Each stage is designed to resolve technical questions before they become production problems.
Send controlled files with material, quantity, finish and target date.
Review geometry, process choice, tolerances and open technical points.
Confirm the manufacturing route, price and lead-time assumptions.
Produce and inspect initial parts for approval where required.
Move approved parts through production, finishing and delivery.

Quality requirements are agreed before production begins, with inspection focused on the dimensions, surfaces and records that matter to the application.
Tell us the end use, functional risks and required documentation so the manufacturing and inspection route can be reviewed correctly.

“Good quality and professional support”
“The quality is excellent.”
“They measured the product prior to shipment and it was exactly as our CAD file specified.”
Send a controlled 3D model or 2D drawing with material, quantity, finish, critical tolerances and target date. STEP, IGES, DXF and PDF files can be reviewed.
Common materials include stainless steel, aluminum, carbon steel and alloy steel. Specific grades, thicknesses and substitutions are confirmed against the drawing.
Yes. The proposed route can cover first articles, prototypes, low-volume production and repeat orders. The best process depends on geometry, quantity and tooling requirements.
Tolerances are reviewed feature by feature against the selected process. Mark critical dimensions and datums so achievable limits can be confirmed before production.
Available reports depend on the project. Material documents, first-article records and dimensional reports should be listed in the RFQ and confirmed before ordering.
Material, thickness, part size, geometry, tolerances, tooling, quantity, finishing, inspection and packaging all affect the quotation.
Include material, quantity, finish, critical dimensions and target date. We will review the manufacturing route and clarify technical questions before quotation.
