The production process of metal fasteners is a delicate and multi-step process. The following is its detailed process flow:
Raw material procurement:
The raw materials of metal fasteners are mainly metal materials such as steel, stainless steel, aluminum alloy, etc. These raw materials need to be strictly screened to ensure that the quality meets the production requirements.
Raw material processing:
The purchased raw materials will undergo a series of preliminary processing, such as wire drawing, shearing, cutting, etc., to meet the subsequent production process requirements. These processing steps can ensure that the size and shape of the raw materials meet the production standards.
Cold/hot forging:
Next, the raw materials will undergo cold or hot forging. This step deforms the material by applying pressure to achieve the desired shape and size. Factors such as forging temperature, speed and mold need to be considered during the forging process to ensure the accuracy and quality of the fasteners.
Forming:
The forged material will be further formed, such as turning, milling, drilling and tapping. The purpose of these process steps is to process and modify the material more finely to meet the specific use requirements and accuracy requirements of the fasteners.
Heat treatment:
After the forming process is completed, the fasteners will be heat treated. The heat treatment process changes the material's structure, shape and properties by heating and cooling, thereby improving the strength and toughness of the fasteners. Common heat treatment processes include annealing, quenching, tempering, etc.
Surface treatment:
The next step is the surface treatment step, which is mainly to improve the fasteners' rust resistance, corrosion resistance and aesthetics. Common surface treatment processes include electroplating, galvanizing, spraying, etc. These treatments can increase the service life and appearance quality of the fasteners.
Quality inspection:
Throughout the production process, fasteners will undergo multiple quality inspection processes to ensure that their quality meets standards and requirements. These inspections include dimensional measurement, mechanical property testing, chemical composition analysis, etc.
Packaging and storage:
Finally, the quality-inspected fasteners will be packaged and stored for transportation and subsequent use.
The entire production process of Metal fasteners needs to strictly follow various standards and requirements to ensure that the quality and performance of the final product meet customer needs.
