Conventional Drilling is available for high production batches making use of jigs and fixtures at low cost. The extensive range of Industrial Plastics available makes it necessary to have a team of very Experienced machinist to produce and supply the correct customer specified size holes and cut outs. At Sentinel we have that Experience, Tufnol, Phenolic, Polyester and Epoxy Materials react very different to Polypropylenes, Perspex, Makrolon®, Lexan®,  and Nylons when routed, drilled, Turned, Milled and Fabricated, with our range of CNC’s your requirements are better understood and guaranteed in our skilled hands.

Certainly, this experience enables Sentinel to produce items from many different types on Industrial Engineering Plastics. The knowledge built up gives Sentinel a leading edge when it comes to Fabricating from Polycarbonate (Lexan®), Polypropylenes (PP), Polyethylene (PE), ABS, PVC and so on. Furthermore, a constant flow of complex and varied fabrications is being repeatedly produced. Thus, enhancing projects through the skills and the latest technologies available at Sentinel.

Around the world, in many different industries, we provide customized engineering parts that for their specific industries our customers.

A capability which requires expertise in understanding Plastics Materials. With our CNC controlled folding press, economic but precise forms can be achieved, providing the customer with a time saving cost reduction option. This combined with our CNC Routing capabilities also offers the customer complex shapes formed with great accuracy.

Necessary when the Material to be formed does not allow for cold bending i.e., Acrylics, or when a complicated form requires heat for the required shape to be achieved.

The process involves passing an electric current through a conductive wire creating a low heat. The Plastic to be formed is then placed over the wire at the precise place where the bend is required. Finally, the parts are folded and allowed to settle in cooling jigs, until rigid enough to be removed.

Materials which require Heat Forming processes are Perspex, Acrylic, PETG,
 Polycarbonate, PVC, Polypropylene,ABS,
Styrene, HIPS, Polyester, Mylar. Parts Include Acrylic Display Shelves, Leaflet holders, Guards, Shields, Barriers, Show Cases, Point of sale.

All information and uploads are secure and confidential.

Notably, Sentinel’s has many years CNC Plastic Machining experience. Furthermore, in that time, have a vast amount of plastic material knowledge.
