Extrusion Molding Processes

Metal Extrusion Forming

Metal extrusion is a highly efficient and precise metal forming process that forces heated metal billets through a shaped die opening to produce long profiles with constant cross-sections. This process is particularly suitable for manufacturing complex-shaped metal profiles and is an indispensable technology in modern industry.

Material Adaptability

• Aluminum Alloys: 6063, 6061, 7075 series

• Copper Alloys: H62, H65, etc.

• Steel Materials: Low-carbon steel, stainless steel, etc.

• 
  

Process Characteristics

     ✓ Capable of producing complex cross-sectional profiles
     ✓ High dimensional accuracy (±0.1mm/m)
     ✓ Material utilization rate up to 90%+
     ✓ Excellent surface finish (Ra1.6-3.2μm)

Typical Applications

• Construction: Window/door profiles, curtain wall frames

• Transportation: Automotive crash beams, high-speed train body profiles

• Electronics: Heat sinks, conductive busbars

• Industrial Equipment: Guide rails, structural frames

Plastic Extrusion Molding

Plastic extrusion is a highly efficient, continuous manufacturing process where thermoplastic material is melted and pushed through a shaped die by an extruder screw, then cooled to form continuous profiles with consistent cross-sections. This cost-effective, high-volume method is ideal for producing plastic profiles, pipes, sheets, and similar linear products.

Material Versatility
• Commodity Plastics: PVC, PP, etc.
• Engineering Plastics: PC, PA, etc.

Process Advantages
✓ Continuous high-volume production
✓ Unlimited length with customizable cross-sections
✓ Smooth surfaces with dimensional stability (±0.1mm/m)
