Shot Metering for Heavily Filled Thermal Gap Fillers

Thermal gap fillers are packed with ceramic fillers that make them thick and abrasive. Specialist shot meters handle them at accurate ratio, laying down precise shots onto battery modules, power electronics and heat sinks. Positive rod displacement metering proportions both materials to an exact volumetric ratio every stroke. Abrasive and heavily filled products that wear out other pump types are handled without losing ratio. Drive options run from pneumatic and air over oil through single servo to dual servo, giving the right balance of cost, control and programmability for each application. Common materials include two part epoxies and polyurethanes for bonding and potting, silicones for gasketing and sealing, MMA for fast structural bonds, and filled thermal compounds for heat management. Rockingham Systems will review the application, the material and the target output, then recommend equipment that fits the job and the budget, rather than selling the biggest machine on the list.

Get the mix and the dose right and everything downstream gets easier. Fewer failures in test, fewer returns and less time cleaning up. From first trial to full production, Rockingham Systems install, train, service and support. Call +44 (0) 1536 628 734 to discuss your application.
