Nowadays, the quality requirements of high quality screws are getting higher and higher. Paying attention to quality is an indispensable condition for the long-term development of a screw factory.

After the products are manufactured, the Shi Shi Tong screw factory will check the surface of the screw for high quality screws, meet the customer’s needs and improve the quality requirements of the screw products. The main considerations for the screw surface are two aspects: Yes: the untreated screws on the surface; the second is the treated screws on the surface; the treated screws are mainly divided into heat treatment and electroplating.

——For the inspection of the appearance of the screw, it is generally divided into three parts. Firstly, whether the appearance of a screw is normal, whether it can pass the inspection of the gauge, etc., there are still defective screws that can exist and cannot exist. Defective screws, etc., are important for the inspection of the appearance.

——For the detection of the hardness of the surface layer of the screw, this test can be said to be an important characteristic of the screw. For the inspection, if it is a screw that does not require heat treatment, it can be directly tested, but if the screw needs to be hardened, Then the hardness check of the screw can be done after hardening.

——For the inspection after screw plating, for this inspection, only the screws with plating are needed. After the plating, the main inspection is whether the plating layer has a surface covering the screw, and the uniformity of the plating layer. Whether it can protect the screw itself and so on.
