1. Selection of stainless steel combination screw material
The materials of stainless steel composite screws mainly include 304 stainless steel and 316 stainless steel. Among them, 304 stainless steel is used in places with less corrosive gases, while 316 stainless steel is corrosion-resistant and used in places with more corrosive gases.
2. Process flow for manufacturing stainless steel composite screws
(1) Selection and preparation of materials. It is necessary to choose stainless steel materials with good quality, smooth surface and uniform color.
(2) Make the screw. The stainless steel screw is manufactured through processing, and the pitch, thread pitch and thread angle must strictly meet the standards.
(3) Make nuts. Through corresponding equipment, produce standard stainless steel nuts.
(4) Assembly. Combine a stainless steel screw and nut together to form a stainless steel combination screw.
(5) Heat treatment. Anneal the stainless steel combination screw to improve its hardness and wear resistance.
(6) Surface treatment. Surface treatment such as electroplating or spraying is carried out on the stainless steel combination screw to achieve the effect of beauty, rust resistance and durability.
3. Quality inspection of stainless steel composite screws
In the production process of stainless steel composite screws, strict quality inspection is required to ensure that the quality of each screw meets the standard.
The main contents of quality inspection include: appearance inspection, size inspection, material inspection, mechanical performance inspection, etc. Only through strict quality inspection can the quality of stainless steel combination screws be guaranteed to be stable.
Four. Conclusion
The production process of stainless steel combined screws requires the support of rigorous production process and high-precision equipment. This article introduces the process and technical points of material selection, manufacturing, and quality inspection of stainless steel composite screws. I hope to provide some guidance for beginners in the production of stainless steel composite screws, so that everyone can have a deeper understanding of the production process of stainless steel composite screws. .
