What are the main steps in screw mold processing?

The first is the design stage. According to the specific specifications of the screws, such as head shape, thread length and diameter, Cold Heading Dies professional design software should be used to design the mold structure to ensure that the mold can accurately produce screws that meet the requirements.

Then comes material preparation. Tungsten Carbide Main Double Sided Die Usually high-quality mold steel is selected. This steel must have high hardness, high strength and good wear resistance to ensure that the mold is not easily deformed and damaged during long-term use.

In the rough processing stage, cutting equipment such as wire cutting machine tools and EDM machines are mainly used to cut the raw materials into a rough mold shape. The focus of this stage is to quickly remove a large amount of excess material.

Then comes fine processing. Use CNC milling machines, grinders and other equipment to finely process the mold so that the dimensional accuracy of the mold reaches a very high standard, such as the dimensional tolerance is controlled within a very small range, and the surface roughness also reaches a very low value, which is crucial for the production of high-precision screws.

Then comes heat treatment. Through quenching, tempering and other processes to improve the hardness and toughness of the mold and enhance the comprehensive performance of the mold.

Finally, surface treatment, such as nitriding, forms a hard nitride layer on the mold surface, which can improve the wear resistance and corrosion resistance of the mold, thereby extending the service life of the mold. During the entire processing process, strict quality inspection is also required, including dimensional accuracy inspection, hardness inspection and other means to ensure the quality of the mold.
