How to choose aluminium extrusion mould?
1,solid aluminium extrusion mould and hollow aluminium extrusion profile mould
The solid aluminium extrusion mould is simple and suitable for hollow pipes with uniform wall thickness, but attention should be paid to controlling the extrusion ratio within the range of 10-45.
The hollow aluminium extrusion profile mould fuses the metal flow through the welding chamber and is suitable for multi cavity or special-shaped pipes, requiring strict control of welding quality.
Adjustable extrusion mould:
The patented design allows for adjusting the extrusion angle by driving the lifting plate with cylinder, adapting to different processing requirements and improving versatility.
1,Design of aluminium extrusion mould structure parameters:
Length of work belt:
Generally, it is 1.5-3 times the wall thickness. If it is too long, it will increase resistance, and if it is too short, it may cause surface defects.
Aluminium extrusion profile mould hole shape and size:
It is necessary to adjust the product section tolerance and shrinkage rate. For complex sections, one cavity aluminium extrusion mould is recommended, while for simple profiles, multiple aluminium extrusion profile mould (2-6 holes) can be used to improve efficiency by 37%
Squeezing ratio matching:
Refer to the cross-sectional diagram of the aluminum profile to select the extruder, ensuring that the extrusion ratio is within a reasonable range and avoiding aluminium extrusion profile mould overload.
3.aluminium extrusion mould material and process requirements:
Material selection
Recommend high heat-resistant materials such as H13 steel, which have hardness of HRC 48-52 and better wear resistance after quenching and nitriding treatment.
Hard alloy aluminium extrusion profile mould are suitable for high-strength production, but the cost is relatively high.
Heat treatment process
Surface treatment processes such as carburizing and decarburization need to be controlled to ensure the machining accuracy and surface smoothness of the sizing strip.
4.Adaptation of production conditions
Optimization of high-speed extrusion
The supporting cooling system prevents aluminum accumulation and optimizes the precision of mold guidance to reduce tensile damage.
Batch adaptation
Choose universal aluminium extrusion profile mould for small batches, and customize specialized molds for large batches (lifespan can be extended by 20% -30%).
5. Maintenance and lifespan management
Regular maintenance
Polishing aluminium extrusion mould cavity, detecting deformation, and combining precise extrusion parameters (temperature, speed) can improve the yield rate
Post processing reinforcement
Strengthen the design of the ejection device to cope with the clamping force between parts and molds, and improve the stability of demolding.
6.Special function design
Porous aluminium extrusion mould layout
If the production of corner materials is changed from single cavity to 4 cavities, the production capacity can be increased by three times, but it is necessary to balance quality and efficiency.
Equipment linkage optimization
Matching specialized extruders (such as hydraulic presses) to achieve full stroke pressure regulation, suitable for the production of large-sized parts.
Through the comprehensive evaluation of the above dimensions, it is possible to balance the quality, efficiency, and cost-effectiveness of aluminum profile forming. In practical applications, the selection plan needs to be dynamically adjusted based on specific product specifications, production scale, and equipment conditions.
