Cold extrusion is a metal forming process that shapes metal at room temperature or slightly elevated temperatures. Unlike hot extrusion, this technique doesn’t involve preheating the material, making it suitable for specific alloys and applications.
Process: In cold extrusion, metal blanks or billets are forced through dies at ambient or slightly elevated temperatures, typically below the recrystallization point. The process imparts precise shapes to the metal, maintaining its strength and enhancing mechanical properties.
Materials: Cold extrusion is commonly applied to non-ferrous metals such as aluminum, copper, and alloys like brass. These materials exhibit improved properties when formed at lower temperatures, making cold extrusion an ideal choice for specific applications.
Quality Requirements: Maintaining material integrity and avoiding defects are crucial in cold extrusion. Quality control measures include non-destructive testing, dimensional checks, and visual inspections to ensure the final product meets specified standards.
Applications: Cold extrusion finds diverse applications in industries requiring precision-formed components. Key applications include:
- Automotive parts (shaft components, gears, fasteners)
- Electrical connectors and terminals
- Aerospace components
- Consumer electronics (aluminum casings)
- Medical devices (hypodermic needles, surgical instruments)
Applicable Industries:
- Automotive
- Aerospace
- Electronics
- Medical Devices
