When it comes to pressure forming we are confident we can advise you on the best component and tool design for your project from our years of pressure forming experience.
The difference between vacuum formings and pressure formings are clear in the end product: Pressure forming moulds have a great finish. Their surface texture is more defined and the corners of the moulds are sharper and more accurate to the original design. You can have logos or certain textures marked into the plastic surface, this cannot be achieved with vacuum forming.
Pressure forming has the same quality of an injection moulding but the tooling costs are significantly less.
In production, it is similar to vacuum forming in thick sheet; they both have short lead times. It’s best suited to low to medium volume production in thick sheet. But can do thin sheet on a larger volume scale.
Pressure forming is very similar to the vacuum forming process; however as well as there being a vacuum from beneath the plastic, it also has air pressure pushed onto the plastic from above. This increases the force on the plastic and so makes the plastic form to the tool more accurately.
Pressure forming enables undercuts, textures and other defining features to be formed on the surface of the plastic moulding.
