Packing

As a fastener manufacturer with 19 years of experience, Zeyao boasts a comprehensive production system, ensuring consistent quality and on-time delivery for every fastener.

1. Raw Material

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

2. Cold Heading

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

3. Thread Rolling

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.

8. Packaging and Shipping

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