Cooling for Appliances and Consumer Electronics

Requirement

Appliance and consumer electronics heat sinks are high volume and price sensitive, and must fit both the product look and internal height limits. Skiving performs well but costs more per part; extrusion is cheaper but constrained by section and fin shape.

Our approach

Split by heat flux: large low-flux areas use low-fin extrusion where only length changes, local hot spots use small skived parts, and every sink in one product is anodized in the same bath to one colour code.

Where the cost comes out

In structure and steps: extrusion removes skiving time and is finished by cutting. Relax tolerances where they do not matter and spend inspection on the mounting face and holes.

Height and assembly

Confirm internal clear height before choosing a section — add area rather than touch the shell. Keep the mounting face machined for proper contact.

Appearance

Anodizing all sinks of one product together is the simplest and most reliable way to avoid shade difference.
