RAMPF Production Systems – high-precision dispensing of thermal pastes

Thermal pastes (gap fillers) are primarily used for power electronics components. Among other things, they cool automotive electronics assemblies, optimizing heat transfer from component to heat sink.

Ever higher electrical power densities mean the thermal energy that needs to be transferred and thus the proportion of filler in the thermal greases is also increasing. Consequently, the highly filled pastes with up to 90 percent fillers place ever greater demands on the pump system because they are prone to sedimentation and act aggressively on the dispensing component. This makes the choice of dispensing pump crucial to process reliability.

Low-wear KDP piston dispensing pumps

RAMPF Production Systems – a leading provider of innovative systems for processing one-, two-, and multi-component reactive plastic systems – has developed low-wear KDP piston dispensing pumps for processing thermal pastes. These pumps benefit from minimal maintenance requirements and maximum precision. The universal systems can apply thermal pastes with a dispensing rate of over 10 g/sec. They are based on the principle of forced volumetric dispensing and operate independently of pressure and viscosity.

The servo-drive technology enables the speed of material discharge to be varied, which means any mixing ratio can be set for two-component materials. Optimum adaptation to the process conditions is rounded off by the servo-electric transmission principle.
