Plastic Vacuum Forming

Understanding Vacuum Forming

The Vacuum process involves heating a plastic sheet until soft. Compressed air is then blown into the chamber forcing the material into a bubble shape. This pre-stretches the plastic for better distribution, and then the mould is raised.

Subsequently, a vacuum is then applied, sucking the sheet onto the mould. Following that the sheet is then cooled using fans and when cool enough, it’s ejected from the mould using compressed air.

In its advanced form, the vacuum forming process utilises pneumatic operating cores to remove undercuts. This improves the level of detail.

Our technical team are keen to share their many years of experience, we can assist customers with the design of their product or part. 

Our design team will analyse your part for potential moulding problems and will advise of any opportunities for improvement.

Most plastics can be vacuum formed, but if in doubt, our technical staff can advise.

All our mould tooling is manufactured and made in-house, and this saves time and money for our customers. This also gives us total control of the project ensuring delivery times and quality requirements are always met.

We have a prototyping/model shop which is used to prove a part or product design prior to production.
