Customized mold opening for radiator aluminum profiles - deep processing of aluminum extruded heat sinks Aluminum profile processing
We provide full process mold customization and deep processing services for radiator aluminum profiles. Based on your product's heat dissipation requirements and structural dimensions, we independently design aluminum extrusion molds, mass produce radiator profiles, and complete high-precision deep processing, including CNC milling, drilling, tapping, grooving, chamfering, wire drawing, sandblasting, anodizing, etc. Widely used in electronic and electrical fields such as LED lamps, switch power supplies, frequency converters, servo drives, communication base stations, and new energy charging piles.

Customized mold making process
Requirement communication - Determine the external dimensions, tooth height, tooth pitch, base plate thickness, installation hole position, etc. of the radiator.
Mold design - combining heat dissipation performance with extrusion technology to optimize cross-sectional shape.
Mold manufacturing - mold steel processing, heat treatment, polishing, mold testing.
Aluminum extrusion -6063/6061 aluminum alloy extrusion ensures straightness and hardness.
Deep processing - CNC cutting, drilling, tapping, countersunking, milling grooves, grooving, etc.
Surface treatment - silver white/black oxidation, sandblasting, wire drawing, passivation, etc.
Inspect packaging - size inspection, deburring, cleaning, protective packaging.
