Design points of mold components

　　The design points of aluminum extrusion molds directly affect product quality and production efficiency. The following are the design points of each component of the mold:

　　1. Mold core (Die)

　　Section shape: Accurately meet the requirements of the profile.

　　Strength and rigidity: Ensure no deformation under high pressure.

　　Diversion hole design: evenly distribute aluminum flow to avoid dead corners and bias.

　　2. Housing

　　Size matching: It fits tightly with the mold core and provides sufficient support.

　　Material selection: High strength, heat-resistant, wear-resistant.

　　Cooling system: Design cooling channels if necessary to extend the lifespan of the mold.

　　3. Port Hole

　　Quantity and distribution: determined based on the complexity and size of the profile to ensure uniform flow.

　　Shape and size: Reduce flow resistance and avoid dead zones.

　　Entrance angle: Optimize flow, reduce turbulence and dead zones.

　　4. Welding Chamber

　　Size design: Ensure that the aluminum material is fully welded to avoid defects.

　　Surface smoothness: reduces friction and improves welding quality.

　　Shape optimization: Promote the flow and welding of aluminum materials.

　　5. Bearing at work

　　Length design: Control the size and surface quality of the profile. Excessive length increases friction, while insufficient length affects dimensional accuracy.

　　Surface smoothness: High smoothness reduces friction and improves surface quality.

　　Angle design: Reasonable angles ensure smooth extrusion of aluminum materials.

　　6. Mold strength and rigidity

　　Material selection: High strength, heat-resistant, wear-resistant materials.

　　Structural design: Avoid stress concentration and ensure uniform force distribution.

　　Heat treatment: Improve hardness and wear resistance.

　　7. Cooling system

　　Cooling channel design: evenly distributed to avoid local overheating.

　　Cooling medium selection: Choose the appropriate medium according to production needs.

　　Cooling efficiency: Ensure rapid and uniform cooling, extending the lifespan of the mold.

　　8. Surface treatment

　　Nitriding treatment: improves surface hardness and wear resistance.

　　Coating technologies such as PVD and CVD enhance surface properties.

　　Polishing treatment: Improve surface smoothness and reduce friction.

　　9. Mold assembly and debugging

　　Assembly accuracy: Ensure that each component fits tightly together.

　　Debugging process: Adjust parameters through trial molding to ensure product quality.

　　Maintenance: Regular inspection and maintenance to extend the lifespan of the mold.
