Does Bergek CNC provide surface treatment services for aluminum cooling plates?

We can provide a variety of common surface treatment processes for aluminum cold plates to meet different application environments and requirements.

We can provide a variety of common surface treatment processes for aluminum cold plates to meet different application environments and requirements. These mainly include:

① Anodizing
② Electroless Nickel Plating
③ Chromate Conversion Coating

The core function of these treatment processes is to delay, to some extent, the corrosion of the aluminum alloy substrate (such as oxidation or reactions with specific coolants), thereby helping to maintain the product's appearance and functional stability over long-term use for CNC-machined aluminum liquid cooling plates used in industrial and power electronics applications. The selection of a specific process should be based on a comprehensive consideration of factors such as coolant compatibility, operating environment, electrical insulation requirements, and cost.

Engineering Guide: Aluminum vs. Steel — How to Choose the Right Thickness

Thickness is more than a number in sheet metal fabrication. Choosing between 1.5mm aluminum and 19 gauge steel affects weight, stiffness, corrosion resistance, and manufacturability. In this guide, Bergek CNC engineers explain how to balance these factors and ensure your design is both reliable and cost-effective.
Can cooling channels be customized through Bergek CNC machining?

A variety of common channel path designs, including U-shaped, serpentine, micro-channel, and pocket milling layouts, can be produced using CNC machining for custom liquid cold plate manufacturing.
What level of machining tolerance can typically be achieved with Bergek CNC cooling plates?

For most CNC-machined liquid cooling plates, the typical control ranges for key tolerances are as follows: the critical channel path depth accuracy can usually be controlled within a range of ±0.02 to 0.05 mm; the flatness of assembly surfaces can generally be guaranteed within ≤0.05 mm; simultaneously, sealing surfaces designed to match silicone gaskets or O-rings can achieve the required surface quality and fit accuracy through precision milling.
How can we ensure that cooling plates processed by Bergek CNC do not leak?

To maximize sealing reliability, we have established a multi-layer inspection mechanism within our production process.
