The radiator profile extrusion die can stably produce radiator profiles with precise dimensions, smooth surfaces, and excellent thermal conductivity in high-capacity extrusion environments, significantly reducing downstream machining and assembly adjustment costs.
Technical specifications:
- Applicable materials: aluminum (common alloys such as 6061, 6063, 6005, etc.), and aluminum-containing composite materials.
- Die material and treatment: typically tool steel die bodies with critical working surfaces subjected to heat treatment and surface strengthening (e.g., nitriding, coating, or shot peening) to improve wear resistance and anti-adhesion performance.
- Production mode: continuous extrusion forming combined with stretching, cooling, traction, and cutting operations, suitable for automated or semi-automated extrusion production lines.
- Accuracy and tolerances: high repeatability in cross-section dimensional control and fit tolerances can be achieved depending on profile complexity and aluminum alloy characteristics; specific tolerances will be confirmed based on drawings and process conditions.
- Service life and maintenance: die life is affected by aluminum alloy friction characteristics, production volume, and maintenance; proper operation, cleaning, and regular maintenance help extend service life and ensure stable production.
Main features:
- Optimized flow channels and cavities: designed specifically for aluminum melt/solid-state flow and cooling characteristics to reduce stagnation and internal stresses, lowering the risk of fin warpage and porosity.
- Precise cross-section control: high-precision die lips and cavity machining ensure geometric accuracy of fin spacing, thickness, and overall height, improving heat-transfer consistency and assembly fit.
- High wear resistance and anti-adhesion: critical contact surfaces undergo surface-strengthening treatments to effectively reduce aluminum sticking, surface roughness, and premature wear, decreasing downtime.
- Modular design and maintainability: supports insert-type, segmented, or replaceable module designs for rapid repair of fins, ribs, and other wear-prone parts, and for section modification or upgrades.
- Precision machining and integration: manufactured using high-precision processes such as CNC and EDM, combined with strict assembly and alignment workflows to ensure seamless interfacing with extrusion, traction, and cooling systems.
- Consideration of capacity and heat dissipation: die design balances thermal performance and production stability, optimizing cooling channel layout to increase production rates and reduce energy consumption.
Applications:
- Aluminum radiators and heat exchangers, HVAC radiator cores, and heat exchanger fins.
- Thermal management components for electronics and power equipment, such as radiator profiles, heat sink frames, and thermal rails.
- Automotive cooling system components, including water-cooled, oil-cooled, and HVAC radiator fins and guide profiles.
- Heat-dissipating profiles for LED and lighting applications, and power electronics thermal structures.
- Other production scenarios requiring high thermal conductivity and strict geometric accuracy for radiator profiles.
