Precision Metal Components For Custom Engineered Solutions
SJ Machinery now offers a broad range of precision metal components for custom engineered solutions produced at the highest quality and exacting standards. With our diversified network, SJ Machinery is connected with certified ISO/IATF manufacturers and distributors of highly engineered mechanical components and assembled solutions.
We offer a complete range of services from design support to precision metal component sourcing with strict quality control throughout the process. We’re able to produce custom casting, forged, and machined metal parts and component assemblies in materials such as aluminum, iron, steel, and zinc.
Our precision metal components offerings feature:
● Die casting
● Investment casting
● Sand casting
● Gravity casting
● Forging
● Machining
Our forging capabilities include access to multiple processes used to produce precision metal parts, including cold, warm, and hot forging techniques. Forged parts are essential in mechanisms and machines when a component requires high strength. Precision Machining involves removing material from a workpiece while adhering to close tolerance finishes. This is accomplished with various methods, including milling, turning, and electrical discharge machining.

The 2&3D drawing format can be PDF, STEP, DWG, DXF and soon, can be sent via email. Wechat, WhatsApp, link.
After clear the demand of customer, we can send you the quotation with PDF format for documentation.
For requirements for confidentiality of drawings, we can signed the NDA before you send drawing.
The feasibility study of drawing is most key point to ensure the part can be fully meet drawing specifications, which is include material, dimension, surface treatment, and testing request.
