Pressure Forming

Pressure Forming

Pressure forming involves forcing a hot plastic sheet against a mold by introducing compressed air to the sheet's outer side. ShehDev Thermoformers, the leading pressure forming manufacturer, recommends pressure forming when your custom plastic enclosure requires features that cannot be achieved by vacuum forming alone.Pressure forming is a process where forming grade plastic is molten into required shape using a combination of pressure & vacuum. Usually, the die used in pressure forming is generally female, this makes it concave. Compressed air is the main force used to push material to the back of the heated sheet so as to enable forming of the plastic into the mold.
