What is Vacuum Training?
Vacuum forming is a simple and economical way of moulding plastics by heating a sheet of plastic and sucking it around a tool or mould to produce a variety of products, from prototypes, storage trays and retail display products to vehicle parts.
The Vacuum Forming Process:
Clamping frames are used to ensure that the flat sheets of extruded plastic are held in place during forming. Customised frame sizes can also be designed to best suit your project specifications.
A singer heater is used to heat plastic up to 6 mm thick and a double heater is used to heat plastic sheets up to 10 mm thick. The heaters are infrared-generated, ensuring that an even amount of heat is applied to the entire surface of the plastic.
It is important to ensure that the plastic is properly cooled before it is released. If the plastic is not cooled properly, deformation or damage to the plastic can occur. Fans are often used to speed up the cooling process.
After the product has cooled, any excess material is removed. Any cutting, drilling and routing required on the project is then completed using various techniques, such as CNC routing.
