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 Vacuum Forming Services
We offer a complete service from design to in-house tooling, to production parts.
CNC Routers allow for 5 axis machining on vac formed parts for greater consistency, accuracy and competitiveness.
This is thanks to our factory, which houses the finest equipment, operated by a highly skilled workforce.
In addition, our CNC Routers allow for 5 axis machining on vac formed parts for greater consistency.
We’re also an environmentally aware company. Committed to using recycled materials where suitable. This and carefully considered manufacturing allows us to reduce our overheads for a competitive edge whilst reducing our carbon footprint.
We offer a complete moulding service from design to manufacture, with the additional services of fabrication, assembly and finishing supported by our extensive in-house toolroom.
Whether prototyping, short or long production runs, we are here to support the needs of all industries.
Moulding in a wide range of plastics, vacuum forming offers product designs that are not achievable in other processes.
- Rigid PVC
- Polypropylene Copolymer
- High Density Polyethylene (HDPE)
- Conductive Polystyrene
- Fire Retardant ABS
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.
