CNC self-tapping screws, as an outstanding representative of modern fastener manufacturing industry, are widely used in automotive, electronics, aerospace, furniture manufacturing and other fields by virtue of its high precision, high efficiency and diversified customization capabilities.CNC technology makes the production of self-tapping screws is no longer confined to the limitations of the traditional molds, and is able to flexibly respond to the demand for a variety of complex shapes and special requirements of the fasteners.
1.Self-tapping screw production process
Design phase: according to customer demand, the use of CAD (computer-aided design) software for three-dimensional modeling of screws to ensure that the design meets the requirements of use and industry standards.
Programming and simulation: Convert CAD design data into G-code recognizable by CNC machine tools, and carry out machining simulation to verify the correctness of the program and optimize the machining path.
Material Preparation: Select raw materials that meet the standards, such as stainless steel, carbon steel, aluminum alloy, etc., for cutting or bar preparation.
CNC machining: Through high-precision CNC machine tools, turning, drilling, tapping and other multi-processes are carried out according to the preset program to realize the precise molding of self-tapping screws.
Heat treatment and surface treatment: According to the material characteristics and usage requirements, necessary heat treatment is carried out to enhance the performance, and surface treatment such as galvanizing and spraying is carried out to improve the corrosion resistance and aesthetics.
Quality Inspection: Advanced testing equipment is used to conduct comprehensive testing of finished products in terms of size, strength, corrosion resistance, etc. to ensure product quality.
Packing and shipping: We protect the integrity of the products during transportation through strict packaging process and ship the products on time according to customers’ requirements.
2.Self-tapping screws customization
Size customization: Provide a full range of customization services from diameter and length to head shape and thread type to meet the needs of different application scenarios.
Material selection: according to customer needs, provide a variety of material options, including high-strength stainless steel, corrosion-resistant alloys, etc., to ensure that the performance of the screws and the use of the environment to match.
Surface treatment: provide a variety of surface treatment options, such as galvanized, Dacromet, electrophoresis, etc., to enhance the corrosion resistance and aesthetics of the screws.
Special features: such as self-locking, anti-loosening, high temperature resistance and other special features designed to meet the use of special working conditions.
3.Self-tapping screws material introduction
