Forming & Moulding
Using state-of-the-art thermoforming techniques, Hampshire Signs and Plastics are able to offer a complete service. From sampling, product development and prototyping up to large scale production runs. Our in house tools facility means we are able to offer our clients a truly bespoke service.
Our processes used include vacuum forming, drape moulding up to 2,500mm and line bending up to 2,000mm. Any one of these processes can be combined alongside other techniques such as CNC profiling and graphics. This give the opportunity to create a countless end products, such as parts, formed boat windows, exhibition and retail stands, protective screens and dispensers to name just a few.
Vacuum forming is a technique using a mould. A sheet of plastic is placed above a mould where it is then heated. Once heated, the plastic sheet becomes malleable. Any air in the mould is then removed, leaving the plastic shaped over the mould. Once cooled, the plastic then stiffens and the mould is removed. This technique is often used for packaging, trays and retail fittings.
Drape moulding involves heating the plastic over a mould, where the plastic will form to the shape of the mould on which it is sitting. This is makes it a good technique for creating a curved product such as shower screens and formed boat windows.
Line bending allows for plastics to be bent. The area of the plastic to be bent it placed over a hot wire strip. This then heats only the area that is to be bent, allowing the rest of the sheet to remain rigid. One the plastic is warm enough, it can be bent by hand and then left to cool. This technique can also be used for boat windows, as well as machine guards and screens.
