Cold Extrusion: Reliable Cold Extrusion from Huaxiao
Cold Extrusion forces room-temperature metal through a die to create net-shape rods, tubes, and cans with superior finish and work-hardened strength—ideal for high-volume precision parts.
How Cold Extrusion Works
The slug is lubricated and driven through the die at ambient temperature; plastic deformation refines the grain, hardens the surface, and holds tight tolerances without chips.
Cold vs. Hot Extrusion
Cold extrusion gives better dimensional control and finish but needs more press force; best for smaller, simpler, high-volume sections.
Materials
- Aluminum—light, smooth-finish parts
- Steel—high-strength fasteners and pins
- Copper—electrical and plumbing components
Industries
Automotive, electronics, and hardware makers use cold extrusion for consistent parts.
How to Spec Your Cold Extrusion Job
- Define material and temper.
- Give final geometry and tolerances.
- State required surface finish.
- Note headed or stepped features.
- Set annual volume for tooling.
FAQ
Why choose cold?
Tighter tolerances, better finish, work-hardened strength, less scrap.
Is machining needed?
Often minimal—cold extrusion is close to net shape.
