What is the manufacturing process of screws?

Introduction: There are many production processes of screws. As the saying goes, interlacing is like a mountain. Every industry has its own rules and procedures, and different goods have different materials, different technologies and different processes. In this case, all our industries have their own procedures. It is very important to have a thorough understanding of an industry, master its business knowledge and understand its basic processes. Even if the screw is so small, its manufacturing process is not simple. Today, Bian Xiao will tell you the basic process of screw production.

The first step is wire rod, which is to find out the brand, product name, specification, material, weight and quantity according to the actual requirements, and then go to the factory to buy the appropriate wire rod. What deserves our attention here is that it will be better to choose low content. Not only to reduce the cost, but also to make screws better in the subsequent process.

The second step is annealing. Annealing is to improve the forging performance of the screw, which is beneficial to its later processing.

The third step is curing. Pickling refers to the surface treatment of screws to make our next step more smooth.

The fourth step is to draw a line. Wire drawing is an essential step of pickling before putting away.

Step five, take the lead. Is to punch out the head of the screw to form the shape of the screw. Course is very important. A screw has a perfect head and shape, giving customers a completely different feeling. So we often encounter bad screw heads. At this time, we are required to know the reason why the screw head is not good when producing screws.

Step six, the gear grinding process operation. It is important to tighten the foundation screws. Ordinary screws with guaranteed quality must pass this test before they can pass the check gauge.

Step 7, heat treatment. Only after heat treatment can the screw maintain its own mechanical properties, which is essential.

The eighth step is electroplating. Electroplating process is generally proposed by customers, and the corresponding surface treatment is carried out. It is also important to keep the surface of the screw beautiful.

Every industry has its own production process, which is not easy to get familiar with. The above is the basic production process of screws, hoping to help readers.
