Our Project

Awesome Project

Extrusion Heat Sink

Extrusion heat sink is light weight and cost-effective, various surface finishing is applicable, suitable for high volume projects.

Heatpipe Heat Sink

Heat pipe heat sink provides a better way of dissipating the heat to be able to maintain the desired working temperature.

Die Cast Heat Sink

Die cas heatsink has the highest productivity, suitable for mass production, due to the high-speed filling, short filling time and fast operation cycle speed.

Cold Forged Heat Sink

Pin fin heat sinks typically have a high thermal conductivity and a low density, which makes them ideal for use in applications where weight is a concern.

Water Cooling Plate

Liquid cold plates are typically made from copper or aluminum, it has a high specific heat capacity and can dissipate large amounts of heat.

Vapor Chamber

A vapor chamber is a key component of cooling systems used in electronic devices. It consists of a flat, sealed chamber containing a small amount of liquid, typically water or a specialized coolant
PT heatsink is the most professional and best heat sink manufacturer in China I worked so far, I send my design, they will point out where the problem is and help to improve.
