CNC milling machining, uses a rotating multi-edge tool to remove material from a workpiece. The most common type is 3-axis CNC machining, which can process most metal and plastic materials with an optimal tolerance of 0.005mm, delivery within 2 days at the latest.
Custom CNC turning service is ideal for producing rotationally symmetrical parts. High precision 0.005mm, high efficiency. Fast delivery time, competitive pricing, with lead times as short as 1 day.
5-axis CNC machining is a high-precision numerical control technology. Its core advantage lies in the ability to machine complex geometric parts at multiple angles without adjusting the workpiece position, achieving tolerances as tight as 0.005mm.
Sheet metal processing is a comprehensive cold processing technique for thin metal sheets. It mainly involves processes such as laser cutting, bending, stamping, welding, and riveting, and the tolerance can be as low as 0.1mm.
SJ-MFG provides customized gear manufacturing service for various industries, producing a wide range of metal and plastic gears. Additionally, we offer assembly service for gears and mechanical components, with tolerances as tight as 0.01mm.
SJ-MFG provides assembly service of various levels and types, which can assemble multiple components according to specific assembly drawings and requirements of customers, and test the perfect operation function after assembly, providing customers with complete assembly requirements and technical support services

Please kindly provide your 2D drawing or 3D files with any supplemental files for tolerances, threads, etc.

Select your material from various metals and plastics, quantity, finishing option, and any special comments, then receive an accurate quote and DFM feedback.

After we receive your payment confirmation, we will start arranging the order and will update the production progress of the order regularly.

Once Production is completed and your parts pass quality inspections, they are shipped to your address as your required.
