Extrusion

 The Magic of Shaping at Room Temperature – Cold Extrusion Process for High-Efficiency Material Utilization. Cold extrusion applies immense pressure to metal at room temperature, causing it to flow plastically within a mold, forming the part in one step. It doesn't rely on high temperatures, but uses pure force to make the metal "obediently" become precise parts.

Typical Applications:

From fasteners and piston pins in automobiles to everyday hardware and electronic product housings, many regularly shaped metal parts requiring strength rely on this process.

Material Conservation: The metal is almost entirely "extruded" rather than "shaving," resulting in a material utilization rate of over 90%, virtually no waste, and well-controlled costs.
Strength and Durability: The cold working process makes the internal fiber structure of the metal denser, like "strengthening" the material, naturally resulting in higher strength and hardness, and greater durability.
High Efficiency: One-step stamping, fewer processes, and high speed make it particularly suitable for mass production of standard parts such as screws, rivets, and housings, ensuring a stable and reliable production rhythm.
