The first is to check the data required for the production of the rivet nut, and to test its wire. For the rivet nut wire, our general manufacturers order it from a professional wire factory, and our own company does not produce wire. At this time, we tell the wire manufacturer what standard, what model, how big and how small we need the wire. When ordering back, we have to check the material of the wire. What we need is iron wire, so it must be iron, and if we need stainless steel wire, then it must be Stainless steel rivet nut. Afterwards, check the standard, model, size and other aspects. See if we can meet our requirements.

Secondly, check the production process of the rivet nut. From the nut machine, the piers are punched, the piers are formed, and the shapes and standard dimensions of all aspects are checked to see if they can meet the customer's requirements, or the sample requirements given by the customer, or the drawing requirements drawn by us according to the customer's samples. . After the trick is checked, we are checking the tapping. Check all threads of the rivet nut. See if you can reach the pass and stop rules, make the pass rules pass, stop rules and stop.

In the second time, some rivet nuts are made of carbon steel, that is, iron, and require electroplating treatment and electroplating in different colors. The color of this electroplating is determined according to customer requirements, some customers need environmental protection, and some ordinary electroplating will do. There are also many aspects to the inspection of electroplating, including the color of the electroplating, the time of the salt spray test after electroplating, etc. When we electroplating, we often encounter the problem of poor electroplating, so what should I do if the pressure rivet nut is poorly electroplated? This is a problem we ponder, and we need to find a solution.

After the comparison, it is the inspection of the rivet nuts when they are shipped. When shipping, select defective products. Put the qualified products to the customers to use. Timely detection of bad product quality problems and good quality control.
