Customized vacuum forming automotive plastic large parts for auto
Heavy gauge thermoforming is a process that converts a flat sheet
of plastic into a functional form.
Since it is a low pressure process, our tools are simpler and less
expensive than other molding processes.
Vacuum forming is a simple process which you may already be
familiar with, where a hot sheet is stretched over a male mold, and
vacuum is applied between the sheet and the mold, pulling the sheet
tight to the mold. Once it cools, the sheet takes on the shape of
the tool. With our 3-dimensional trimming equipment, we can then
trim out the finished part with a high degree of accuracy and
repeatability. There are an infinite number of applications of this
Pressure forming is a more complex process where the hot sheet is
drawn into a female mold, and then a tank closes off the mold and
pressure is introduced on the non-mold side while vacuum is applied
on the mold side. The sheet is drawn very tightly to the mold, and
the resultant part then has all of the fine detail of a molded
part, but with less tooling. This is the process of choice where
you need a very highly cosmetic look, identical to molding, with
tight radii and fine surface detail but the part size is large and
volumes are just too low to justify injection molding. Many
industrial machines and medical and scientific equipment employ
pressure formed enclosures to give them a distinctive and

Once a vacuum forming has been created out of a sheet of plastic, a
finishing operation will be needed in most cases to turn it into a
usable product. Common vacuum forming finishing methods include:
Guillotining: The product is cut out of the sheet by pressing a
blade through the product into a die underneath. This is a clean way of removing vacuum formed parts
from the material sheet. It doesn't require a special cutting tool
to be made for an individual product and is therefore suitable for
low volumes of parts where straight lines are no problem. Cutting
only straight lines and being a fairly slow approach compared to
other finishing methods, guillotining can be expensive for projects
with larger, more complex quantities.
Drilling: If simple round holes are the required finish, manually drilling
them is a good solution for small quantities. Drilling guides can
be used to ensure holes can be drilled quickly in the right place.
As this is a labour-intensive method, it is only suitable for small
Roller cutting: Process whereby the vacuum formed product is placed
on a custom made cutter and pushed through a roller cutter machine.
An efficient way of cutting vacuum formed items from the original
sheet of vacuum forming material. The cutter can also cut any
necessary holes, such as cable or access holes, at the same time.
Roller cutting is suitable for fairly large items, where precision
alignment is not required. As the vacuum formings and the cutter
are rolled sideways through the roller cutter machine, some
misalignment can occur. Roller cutting can't be used for making
holes or features in the sides of vacuum formings, as the cutter
tool always cuts vertically from the bottom.
Press cutting: This is a very precise method of cutting which uses
a press and a custom precision made cutting tool. This method is
very suitable for items where the roller cutter process wouldn't
achieve the precision required. It's often used for punching very
small finished items out of a plastic sheet, rather than punching
features into a product. Press cutting can't be used to make
features in the sides of vacuum formings.
Cutting with a CNC machine: Machining is a very precise method of creating holes &
features. The real advantage is that it can be used to create
features in the sides of vacuum forming, e.g. guide rails for a
tray that needs to slide onto shelving. It can also cut sidewalls
of a different depth than the pockets - something which cannot be
done with roller or press cutting.
