We purchase high-quality metal wire and strictly sort it into batches upon arrival, preparing it for subsequent processing.

A cold heading machine processes the raw material into the basic shape of the fastener.

Next, threading, also known as threading, is performed to ensure the screw or bolt has a standard, clear profile.
4. Automatic Lathe Processing
Fully automatic lathes are used to further refine parts, including chamfering, turning, and slotting, to enhance dimensional accuracy.
5. Benchtop and CNC Lathe Finishing
For complex or customized fasteners, we use benchtop lathes and CNC machines for further processing to ensure they meet specific customer requirements.
6. Quality Inspection
All products undergo rigorous manual and automated inspections to eliminate defective items and ensure that every shipment meets customer standards.
7. Functional Testing
Some products undergo specialized testing equipment to verify key indicators such as hardness, thread accuracy, and external dimensions.

Products are sorted, packaged, labeled, and boxed automatically or manually, and then neatly stacked in the warehouse for shipment.
