DP Seals, supplier of precision custom rubber seals and mouldings, is supplying Hypertac, supplier of high performance interconnect solutions, with interfacial seals for its high-density PCB connectors.

Ensuring the accuracy and precision demanded by these fluorosilicone seals – used in challenging applications such as aerospace and defence, mass transit and marine – set DP Seals one of its toughest tooling tests.

Hypertac’s PCB connectors use 0.6mm pins in multiple rows on a 0.953mm staggered pitch, dimensions the tool needed to match accurately whilst adding detail essential in ensuring a tight seal against dirt, oil and other liquids; the seal itself is just 3mm thick. DP Seals fabricated a set of tools where each individual connector pin is represented by a custom-designed 0.7mm minimum diameter tool steel pin, held in place with a M0.6 countersunk screw just 2.5mm long.

“Hypertac gave us one of our most demanding tooling tests for many years,” notes Russell Willis, DP Seals’ tool room manager. “We even had to manufacture our own Philips screwdrivers for the job.”
