VACUUM FORMING
How Vacuum Forming Works
When larger parts are required, especially with thin wall
requirements, Vacuum Forming is a proven process. Vacuum Forming, because it is
so versatile, provides an excellent opportunity for experimental and first time
production.
Vacuum Forming consists of heating a plastic sheet held in
a frame until it is soft and pliable. Then the mold is placed directly under the
sheet and slight pressure is applied to seal the plastic to the upper mold edge.
A vacuum is applied through small holes in the mold cavity and the atmospheric
pressure forces the softened sheet against the contour of the mold walls. Upon
cooling, the product has solidified and when removed it retains the shape of the
mold. Industrial products are typically a vacuum forming production
specialty. Such items as covers, housings for motors, waste containers, liquid
transporters, ice drawers and water fountains are all quality manufactured with
the Vacuum Forming process. Acrylic materials is especially effective in the
formulation of VF Products. Low breakage is experienced, temperature variation
are no problem and resistance to chemicals is excellent.
