In the process of screw forming, the mold that produces the screw is first inspected. Only a good mold can produce a good screw product. Then to test of equipment for manufacturing screws, which is beneficial to our smooth manufacturing.

Then we need inspect the appearance of screws to see if if it is smooth,and check the size and diameter,length of the specification complies with standard or our customer requirments.

Third is the detection of screw threading,the first thing we concern about is the thread mold,the good thread mold can produce the screw thread can go gauge,nogo gauge.there is also testing for thread pitches.It is also necessary to ensure compliance with the standards and user application.

The last inspection is for surface treatment and salt spray test,electroplationg process.we need look at the color of screw,and if it is smooth surface.also the salt spray test how many hours will rust for screw.our purpose is screen out those screws that don nt meet standard and deliver high quality products to our customer.Ensure the quality of every screw we sold.
