Description

Thermal paste dispensing with METER MIX® Systems

Specifically developed to meet the increasing demand for dispensing small shots of homogeneously mixed two-part, highly abrasive materials, the PAR 2EH incorporates Tungsten Carbide-hardened wetted parts with mechanically linked rod-displacement metering pumps to provide precise dispensing of micro shot sizes down to 0.04ml. This is combined with the added benefit of electric servo drive speed and shot size control. The system is a solution for gap filling and potting processes, where thermal interface materials are applied to transfer heat away from the component.

The PAR 2EH provides reliable, proven fixed-ratio metering control during dispensing, and its compact design allows it to be mounted directly onto an articulated robot for accurate point of application dispensing. The PAR2EH can also be interfaced with automated systems for fully or semiautomatic applications. Incorporating robust and proven metering and mixing principles, the advanced PAR 2EH embodies the perfect solution to many small shot applications. Typically, this system is supplied with drum unloading transfer pumps for larger volume production.
