Thermal Grease Coating

Features:

• Automated process - Replaces manual attachment of heat sinks, improving process efficiency and accuracy.

• Flexible coating size adjustment - The shape and size are no longer limited to pre-cut heat sinks, and can be flexibly adjusted and coated to the desired shape.

• Progressive Cavity stator material can be selected - Depending on the temperature resistance, wear resistance, acid and alkali resistance requirements of different coating materials, the most suitable stator material can be selected.

• Faster and more accurate than pneumatic needle coating - The pressurized feeding system is equipped with a screw valve for quantitative control, ensuring stable and fast discharge.

• Progressive Cavity quantification system - The Progressive Cavity valve is used for quantitative control, overcoming problems such as high metal powder content and viscosity of thermal paste. The discharge accuracy can be maintained within ±1%.

• Prevent material sagging - The screw valve controller can control the speed and direction of the progressive cavity valve. When the coating stops, the progressive cavity valve reverses to prevent material sagging.
