Liquid Level Detector

For this project, PD Models worked closely with the client to produce a working Liquid level detector to be used in industrial refrigeration units. The printed circuit board had to be entirely encased in Epoxy resin, capable of withstanding the chemicals contained in the refrigeration unit. Also a reliable seal between the clear epoxy and the CNC Machined Steel part was required.

Initially the epoxy posed many problems with shrinkage and gassing since the material was never designed for this process. However these problems were overcome to provide the customer with many polished models, for use as production parts. After the prototype stage was complete, PD Models continued to work with the client, providing advice in the hard tooling process, while at the same time providing a cost effective short manufacturing run to keep their orders fulfilled while Steel tooling issues were resolved.
