Sentinel Plastics Ltd deals solely in plastics, including rigid-Sheet & rod PVC, a plastic material that is chemically non-reactive, and can be Machined to close tolerances and finishes. Notably, PVC is the eldest Sheet product within the marketplace. Notably used for corrosion resistant tanks, ducts, fume hoods, and pipe. Also, PVC possesses excellent electrical properties, outstanding chemical resistance, low moisture absorption, good dimensional strength, and good compressive strength. Once these properties are coupled with PVC’s flame resistance, and chemical bond ability. it is easy to understand why PVC is thus often the Material of choice within the corrosive resistant trade. Key Features: Good chemical resistance and is easily thermoformed. Very good electrical Insulation. Applications: Machined Components, signage and prototype models. Chemical apparatus, plugs, tank linings, battery separators, insulators, signs, pallets, prototype models.

As a rule, PVC Sheet can be safely heated up to 120°– 140°C and at this temperature behaves in a manner that enables it to be formed into complex shapes with tight curves and deep draw. Hot line bending requires that the PVC sheets be softened along a narrow line by a strip heater, usually a hot wire.

Customer confidence and satisfaction is at the heart of everything we do!

Sentinel Plastics is a long-standing, trusted plastics company that has been CNC machining and fabricating all types of industrial plastics since its inception in 1989.

Whether your requirement is one-off or high batch work, the capacity available is ever-increasing — meaning lead times are always kept to a minimum. The quick turnaround times, combined with quotes (which are in the main supplied on the same day as requested), is one reason many customers constantly return to Sentinel for all their CNC machined and fabricated parts requirements.

Importantly, with our skilled team of Machinists, we can manufacture a huge variety of Components for just about any industry. Our modern CNC mills, saws and lathes allow us to offer our CNC Machining in the UK for one-off prototype Components or for large bulk orders of Components all created with great precision. We have a great knowledge of our tools and the Materials we work with, which we make great use of; providing advice on Material selection to ensure that you get the most suitable Material for your project.
