Manufacturing Technique


1. RAW MATERIALS
 
Semi-Autic The raw materials are made by coiling, annealing, pickling, and wire drawing. The lower the content of Al and Cu, the better the performance
2. COLD HEADING
The principle of screw forming is to perform cold or hot multi-station upsetting according to the plastic deformation of the metal to meet the shape and size requirements of the required parts. It is characterized by less cutting or no waste, low cost, high efficiency, and high finish. Compared with cutting processing, its output has high strength.

 
3. THREAD ROLLING
The principle of thread rolling is to use the plasticity of metal to roll the formed semi-finished products to achieve the required thread specifications. The tooth rolling machines currently used by our company are flat reciprocating tooth rolling machines produced in Taiwan. With good accuracy and high efficiency, it is in the forefront of the domestic industry.
