Here at JA Harrison, we can produce high quality machined components manufactured from our PTFE Polymer (ADFLON grades). From the raw polymer to a high precision machined part, JA Harrison control every step of the PTFE machining process from their Manchester site.

From large diameter 2000mm down to the smallest size of 5mm we can meet our customer’s demands.

With 3 machining centres of which, the largest machine has a bed size of 2000mm x 1000mm and a 4 Axis lathe. Therefore, this machines up to 450mm diameter complement the machining department. Which is made up of barfed machines for large batch sizes. It also has a router which has a cutting depth of 100mm on a bed size of 3000mm x 2000mm.

Having off line programming capabilities helps to keep our downtime to minimum and allows us to meet our customers requirements.

Our typical products that we machine are PTFE envelopes for use within the chemical and pharmaceutical industries. Including Bellows, Valve seats, Chevrons, Washers, Static Mixers, bearing housings, Wedge seals, Tri-clovers, Bushes, diaphragms and seals.

With our CAD/CAM suite at Manchester we have the capabilities to reverse engineer customer’s parts from drawings to CNC machining programs.
