About us
A precision machining shop built around engineers, measurement and repeatability.


Manufacturing services
Precision parts, built around your drawing
Jingchuan Precision handles enquiries for custom CNC-machined parts. Our manufacturing and shipping location is in Dongguan, Guangdong; our registered office is in Chifeng, China.
Start with the requirements
Send a drawing or CAD model with the material grade, quantity, critical tolerances, surface finish and inspection requirements. These details form the basis of a technical review and quotation. Equipment selection, achievable tolerances, documentation and delivery dates must be confirmed for each project.
Clear information before production
Use the quotation stage to agree on drawing revisions, acceptance criteria, material certificates and any first-article inspection requirements. If confidentiality terms are needed before sharing a drawing, contact us to arrange an NDA.
Contact
Upload your files through the quotation form or contact [email protected]. Please identify any features that need particular attention so they can be addressed during the technical review.
What we stand for
Engineer-reviewed quotations
Each RFQ is checked by a manufacturing engineer for tolerance stack-up, wall thickness, tool access and cost drivers. You receive a DFM note, not just a price.
Documented and traceable
Material certificates (EN 10204 3.1), dimensional reports, RoHS and REACH declarations. Every lot is traceable to raw material and operator.
Confidentiality by default
Drawings are stored on access-controlled servers, never shared with third parties, and mutual NDAs are signed before file transfer on request.
One supplier, full process chain
Machining, heat treatment, surface finishing, laser marking and assembly are coordinated by us. Fewer interfaces, fewer delays, one responsible party.

STEP, IGES, X_T, DWG, DXF, PDF or STL. Every file is treated as confidential and covered by NDA on request.
