Aluminum Extrusion Die-Casting

Extrusion Dies Structure

  • Upper Mold: This is the top part of the mold, and usually has extrusion and guide holes, guiding the aluminum material. The upper mold design should consider strength and durability.
  • Lower Mold: Works with the upper mold to form the mold cavity. The lower mold structure ensures the stability and consistency of the aluminum during extrusion.
  • Mold Cavity: The shape and size of the mold cavity determine the final cross-section of the aluminum profile. The mold cavity design is usually customized according to the customer’s product requirements.
  • Guiding and Positioning System: Ensures the upper and lower mold alignment, and prevents deviation during extrusion. Common guiding systems are guide pillars, guide sleeves, and positioning pins.
  • Cooling and Heating System: In some cases, to ensure smooth extrusion, cooling or heating channels may be set within the mold to control its temperature.

Molds

  • Standard Molds: For common aluminum profiles with simple mold cavity design.
  • Complex Molds: For complex shapes or profiles with special requirements, such as curved and multi-cavity profiles.
  • Multi-Hole Molds: For extruding multiple profiles or different cross-sections at the same time, increase production efficiency.
  • Custom Molds: According to the customer’s product requirements, often involve special materials or techniques.

Functionality of Extrusion Dies

Aluminum extrusion dies are critical for precision, efficiency, and versatility in manufacturing.

Specific Shape Formation Needs

Extrusion die designs can be customized to client requirements, covering shapes such as:

  • Square and Rectangular Profiles: Used in construction, furniture, and other structures.
  • Round Tubes: Widely applied in construction, automotive, and machinery manufacturing.
  • Complex Cross-Section Profiles: Including trapezoidal, U-shaped, and T-shaped profiles, suitable for specific applications like frames and supports.
  • Specialty Profiles: Such as heat sink profiles and duct profiles, meeting unique industry needs.

High Precision

The design and manufacturing process of the dies emphasizes precision, achieved through:

  • Computer-Aided Design (CAD): Utilizing CAD software for accurate design, minimizing human error.
  • Numerical Control (NC) Machining: Using CNC machines to manufacture the dies, ensuring the dimensions match the design exactly, and preventing size deviations during subsequent processes.

Enhancing Production Efficiency

  • Combining Heating and Extrusion: Heated aluminum can be quickly formed through the die, completing the entire process within seconds, significantly speeding up production.
  • High-volume production capabilities: A single-die design can support the extrusion of numerous aluminum profiles, ideal for high-demand production lines, reducing the production time per piece.
  • Integrated Production Flow: The design of the extrusion machine allows for quick and easy die changes during normal operation, enhancing production continuity.
  • Reduced Downtime: Efficient die designs decrease wear and tear, reducing downtime when changing dies, thus ensuring a smoother production process.

Versatility

  • Flexible Die Changes: By designing different dies, various types of aluminum profiles can be produced on the same extrusion machine, catering to diverse client needs.
  • Rapid Market Response: The flexibility in die design allows aluminum profile manufacturers to quickly respond to market changes, develop new product types, and enhance market competitiveness.
  • Meeting Custom Needs: Customized dies offer personalized design and manufacturing services based on specific client application requirements, ensuring each client gets products that meet their needs.
