Cold Extrusion Components
We supply precision cold extrusion components from Coldex AG, a renowned Swiss manufacturer known for outstanding quality and innovation. With Coldex’s expertise in impact extrusion, we offer durable, high-performance parts that combine precision, efficiency, and sustainability — tailored to meet the highest industry standards.
Cold impact extrusion is a highly efficient metal-forming process, mainly for aluminium, where a billet or slug is shaped under high pressure at room temperature.
Advantages of Impact Extrusion Technology
Material Efficiency
-
Near-net-shape forming reduces or eliminates the need for costly finishing operations.
-
Very low material waste compared to subtractive machining processes.
-
Efficient use of raw materials aligning with modern sustainability goals.
Excellent Surface Finish
-
Produces smooth surfaces directly from the die.
-
Tight dimensional tolerances enable consistent, repeatable accuracy and quality.
-
Dense, pore-free structures of high strength and material hardness.
Versatile Applications
-
Capability of producing complex geometries.
-
Particularly effective for lightweight components made of aluminium.
-
Ideal for large-volume
items such as housings, cups, timing belt pulleys, pinions and many other parts.
