Testing & Assembly

Both Walter Frank and Francis W Birkett have an extensive history of adding value to products and services via our assembly processes.

Our assembly operations are managed in a stand-alone production cell, supported by our electronic MRP system. The system has had bespoke modification applied to enable us to launch unique bills of materials that interact at various levels of the manufacturing process. It often requires a very detailed bill of materials interacting over multiple levels to provide the final product.

This complexity can only be supported by our industry-leading manufacturing platform, which offers sand castings, centrifugal castings, die castings, shell castings, bought-in castings / bar / stampings released into conventional or CNC machining centres. They are then brought together by warehouse operations into the assembly centre, where highly defined SOP’s are utilised, along with painting, plating, polishing, degreasing, pressure testing, NDE, packing and certification.

Testing is often based on non-destructive examination by utilising dye penetrant or radiographic procedures. A great deal of our product is supplied to applications requiring PED approval; therefore a large proportion of our testing involves hydrostatic testing, from a few bars up to very high pressure. Our testing procedures are supplemented by detailed certification requirements from the foundry / mill, and witness testing during all or part of the process is easily accommodated.
