Custom Aluminum Extrusion Service

We specialize in creating custom aluminum heat sinks using advanced aluminum extrusion technology. Here’s how our process unfolds: First, we heat the aluminum ingot to a high temperature, typically between 520 and 540℃. This turns the aluminum into a liquid that is then forced through an extrusion die featuring specific grooves, under high pressure. This step forms the basic shape of the heat sink. These initial forms are then trimmed to the required lengths.

Beyond aluminum extrusion, most heat sinks also undergo CNC machining for finer details. This includes tasks like drilling holes and tapping. However, for simpler shapes or small-volume orders, we can bypass the extrusion process and directly use milling or wire cutting techniques. This approach is particularly efficient for handling smaller orders.

Advanced Aluminum Extrusion Technology


1. The material we use is aluminum alloy, specifically AL6061 and AL6063.
2. The tooling lead time is usually 2-4 weeks, but it can vary depending on the project.
3. Our post-machining services include full service CNC cutting, threading, slotting, face milling, etc.
4. Our processing procedures are as follows: product design, drawings checking, mould making, extrusion, cutting, holes drilling, precision machining, surface treatment, quality inspection.
5. Our tolerances are ± 0.02mm unless otherwise specified.
