What are the manufacturing processes of self-tapping inserts?

The manufacturing processes of self-tapping inserts typically involve several steps to create these threaded fasteners designed to create their own threads within materials like plastics and wood. Here are the general manufacturing processes involved:

1.Material Selection: Self-tapping inserts can be manufactured in different kinds of materials, including stainless steel, steel, brass, etc. The choice of material depends on the requirements of the application, such as corrosion resistance, strength, etc.

2.Punching or Cutting: The starting point for making a threaded insert is usually a small hole, which can be formed in the base material by methods such as punching or cutting. The diameter and depth of this hole should match the size of the threaded insert.

3.Thread cutting: Next, use an appropriate tool, such as a threading cutter, to cut threads matching the size of the insert in the small hole you just made. This is a critical step in ensuring that the insert will hold securely in the substrate.

4.Plating treatment (optional): In order to improve the corrosion resistance of the self-tapping screw sleeve, the screw sleeve can be surface treated, such as galvanized, nickel-plated, etc. This helps extend the life of the insert.

5.Cutting and forming: Cut the finished threaded sleeve to an appropriate length, and make the shape more regular and precise through forming and other processes.

6.Quality inspection: After the production is completed, the quality inspection of the screw sleeve will be carried out to ensure that the size and thread quality of the screw sleeve meet the standard requirements.

7.Packing and distribution: Quality inspected inserts are packed and ready to be distributed to the market or to customers.

This is a general fabrication process and actual fabrication may vary by manufacturer, insert type, and application. When making self-tapping threaded inserts, it is very important to ensure that the corresponding production standards and quality control measures are strictly followed to ensure the performance and reliability of the threaded inserts.
