Plastic Fabrication

At Sentinel Plastics, our plastic fabrication capabilities encompass a wide range of processes and techniques, each carefully selected based on the material type and design requirements. Thanks to our extensive experience working with many different forms of plastic materials, we’re able to determine the most effective fabrication methods for every project.

Our capabilities include cold folding, heat line bending, forming, and joining through adhesives or welding. We also offer complete assembly services, using mechanical fixings, adhesives, or welded joints to ensure durable and precise finished products.

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

Cold Bending

Our fabrication capability demands specialist expertise in understanding plastic materials and their behaviour under different processing conditions. Using our CNC‑controlled folding press, we can produce accurate and economical forms, offering customers both cost and time savings without compromising precision.

When combined with our advanced CNC routing capabilities, this allows us to create complex, high‑accuracy shapes — perfectly matching design specifications and ensuring consistent, repeatable quality across every component.

Complex Guards, High Voltage Shrouds, Intricate Covers, Acrylic Fabrications, are all included in Sentinel’s capabilities.

Hot Wire Forming (Line Bending)

Heat forming is essential when working with materials that cannot be cold‑bent, such as Acrylics, or when a complex shape requires thermal softening to achieve the desired form.

The process works by passing an electric current through a fine resistance wire, generating controlled heat. The plastic sheet is carefully positioned over the wire at the point where the bend is required. Once the material softens, it is folded into shape and placed in cooling jigs until it becomes rigid enough to handle and retain its new form.

Common materials requiring heat forming include Perspex®, Acrylic, PETG, Polycarbonate, PVC, Polypropylene, ABS, Styrene, HIPS, Polyester, and Mylar. Typical products made using this method include acrylic display shelves, leaflet holders, guards, shields, barriers, showcases, and point‑of‑sale displays.
