How to Enhance the Production Efficiency of Aluminum Profile Extrusion? Foshan changyin will provide you with the answers!

The process methods for improving the yield rate of Aluminum Profile extrusion involve multiple aspects, including raw material control, production management, mold management, temperature control and process optimization.

1. Improve the quality of ingots

Ingot is the raw material for aluminum profile extrusion production, and its quality directly affects the yield rate. The ingot should have uniform structure, fine grains, no slag inclusion, pores, segregation, cracks and other defects. Specific measures include:

Selecting high-quality aluminum rods: Using aluminum rods with high levels of refinement, alloying, grain refinement and homogenization can reduce mold wear and increase extrusion speed. Strictly inspect the ingots: Conduct strict quality inspections on the ingots to ensure that defect-free ingots enter the extrusion process.

2. Precisely calculate the length of ingots

Precise calculation of the length of ingots can reduce process waste and improve the yield rate. According to the specifications of the extrusion machine, the size and quantity of the products, calculate the required length of the ingots using the principle of equal volume or equal mass.

3. Optimize extrusion process

Appropriately increase the extrusion coefficient: Based on the extrusion ratio of the product, the length of the cold bed, the outer diameter of the extruded piece, the length and diameter of the extrusion barrel, etc., determine the tonnage and extrusion coefficient of the extrusion machine reasonably. When the extrusion coefficient is large, it can increase the extrusion speed, reduce technical waste and improve the yield rate. Control the "three temperatures": namely, the heating temperature of the aluminum rod, the mold temperature and the temperature of the extrusion barrel. Reasonable temperature control can ensure the smooth progress of the extrusion process and reduce the generation of waste. Optimize extrusion speed: According to the alloy type, the cross-section of the product and the extrusion equipment, reasonably set the extrusion speed to ensure the quality and production efficiency of the extruded products.

4. Strengthen mold management

Improve mold design level: Use advanced mold design software for precise mold design and simulation analysis to reduce the number of mold trials and increase the first-time qualification rate of molds. Strengthen mold maintenance: Regularly perform nitriding treatment on molds to increase their hardness and surface finish, and extend their service life. Accurately record mold dynamics: During extrusion, accurately record the weight of each set of molds that extrude a single profile piece to provide reliable basis for the next production.

5. Use clamping pads and hot shearing ingot furnace

Use clamping pads: During the stretching and straightening of profiles, using clamping pads can reduce the deformation of the head and tail of the profiles, shorten the cutting length of the head and tail, and improve the yield rate. Use hot shearing ingot furnace: The hot shearing ingot furnace can avoid ingot sawing, reduce aluminum chip loss, and adjust the cutting length at any time according to the dynamic weight of each profile piece of the mold to obtain any required length of ingot blanks, further improving the yield rate.

6. Optimize sawing process

Select thin saw blades: During the sawing process of finished products, using thinner alloy saw blades can reduce sawing loss and improve the yield rate. Reasonably determine the cutting length and multiple times: According to the specifications and quantity of profiles, reasonably determine the cutting length and multiple times, reduce sawing waste.
