Die Manufacturing Process
Aluminum extrusion dies are the core tools for producing aluminum profiles. Their manufacturing process is precise and complex, mainly involving the following key steps:
1Design & Simulation
· Customer Input Analysis：Analyze the profile drawings or samples provided by the customer to confirm technical requirements (dimensions, tolerances, alloy, etc.).
· Die Design：Use CAD software (e.g., AutoCAD, UG) for die structure design, including the die, backer, housing, etc. The core is designing the weld chamber, portholes, bearing length, and angles.
· Finite Element Simulation：Use professional software (e.g., HyperXtrude, QForm) to simulate metal flow, stress distribution, and temperature field during extrusion. Optimize the design to avoid defects and ensure uniform material flow.

2Material Preparation
· Material Selection：Select premium hot-work die steel (e.g., H13, SKD61) with high purity and uniform structure.
· Blanking & Rough Machining：Cut the die steel forging into required sizes and perform preliminary turning and milling to form a general outline.
· Blanking & Rough Machining：Cut the die steel forging into required sizes and perform preliminary turning and milling to form a general outline.
3Precision Machining
· Heat Treatment：Perform quenching and multiple tempering to achieve high hardness (typically HRC 46-50), high toughness, and good thermal fatigue resistance.
· CNC Precision Machining：
· Milling：Use five-axis CNC machining centers to precisely mill complex 3D shapes such as the die face, portholes, and weld chamber.
· Wire-Cut EDM：Use slow wire-cutting EDM machines to high-precision cut the bearing profile and special-shaped inner holes.
· EDM：Use formed electrodes to machine complex grooves or fine features difficult to achieve by milling.

4Surface Treatment & Finishing
· Polishing：Manually or mechanically polish key flow channel areas like the bearing and weld chamber to reduce surface roughness and friction resistance.
· Surface Strengthening：Optionally perform nitriding (gas, liquid, ion) or PVD coating to significantly improve the die surface's wear resistance, anti-sticking, and corrosion resistance.
· Marking & Inspection：Mark die number, specifications, etc. Perform dimensional inspection with CMM and visual inspection of surface quality.
