Aluminum Alloy Mold Manufacturing
Manufacturing aluminum alloy processing molds directly determines aluminum’s quality and service life. Aluminum extrusion tooling has specific characteristics, leading to high requirements for aluminum profile mold molding technology.
Challenges in Mold Materials
During extrusion, molds must endure high temperature, high pressure, and high friction. Manufacturers use high-strength heat-resistant alloy steel to meet these demands.
The processes of smelting, casting, forging, heat treatment, electrical machining, machining, and surface treatment for such steels are highly complex.
Advanced production equipment and skilled techniques are essential for mold manufacturers.
Precision and Surface Quality
To extend mold service life and ensure product surface quality, manufacturers maintain mold cavity roughness between 0.8-0.4 μm and mold plane roughness below 1.6 μm.
Special polishing processes and equipment are required to meet these standards.
High-precision extruded products, such as those with wall thicknesses around 0.5 mm and tolerances of ±0.05 mm, demand ultra-precise mold accuracy of 0.01 mm.
Manufacturers achieve this using CNC lathes, machining centers, and slow-wire processing machines.
Complex Cross-Sections
The cross-sections of aluminum profiles are often intricate.
Thin-wall hollow aluminum profiles and porous hollow-wall profiles require special extrusion mold structures.
A single mold may contain multiple shaped cavities with varying dimensions, complex features, and numerous arc corners.
This complexity necessitates the use of specialized structures and processing techniques.
Efficiency and Adaptability
Aluminum processing products often involve small batches, frequent mold changes, and diverse designs.
Manufacturers prioritize improving production efficiency and reducing the mold-making cycle.
They quickly modify processes to produce accurate molds based on drawings, minimizing the need for repairs.
Advanced Techniques and Equipment
Extrusion tools come in diverse types, have complex structures, and require strict assembly accuracy. To meet these challenges, manufacturers utilize specialized equipment, processing methods, tooling, and heat treatment techniques.
Additionally, advanced heat treatment and surface strengthening processes improve mold quality and service life.
These processes ensure optimal hardness and surface quality, especially for challenging extrusions and unique molds.
