Plastic sheet is commercially available in a wide variety of grades, thickness and colours.
Materials such as styrene and PVC are most suited to vacuum forming. Other materials such
as acrylic, polypropylene and polycarbonate will mould but difficulties may be encountered.
It is not within the scope of this manual to attempt to list all the potential problems and their
solutions. It is recommended that the newcomer to vacuum forming gains experience and
confidence with easily formed materials before moving onto the more difficult materials.
Post Forming Operations

After forming
After forming, most plastics can be subsequently heat formed to add such details as folds or
clips. Although many plastics can be printed, and in some cases painted, the presence of
release agent used to help free a tight moulding may make the surface resistant to further
decoration.
Trimming
An ideal moulding will be ready for use when removed from the machine and requires no
finishing. However, most mouldings do require trimming before they can be used.
There are numerous methods available for this process.
Thin materials can be trimmed with a sharp knife. Shaped cutting dies can be used to cut out
intricate shapes. If no flange is required on the finished product then a trimming saw mounted
in a pillar drill will cut the moulding in a horizontal plane to free it from the surrounding
material.
In mass production environments the range of equipment available for this requirement
encompasses clicking presses, roller presses, routers, horizontal band saws, water jet
cutters, laser cutters and many others.
