Vacuum forming is performed by heating a thermoplastic material till it reaches a pre-set melt flow index at which point the material can be formed over a TOOL / Mould using Vacuum.
Typical range of thermoplastic materials use in Vacuum Forming include:
All 2D vacuumed plastic components are made from a tool. During the proto-type stages the tool is made from wood or MDF and made in house on our 3D routers or made in our Tooling Dept.
Tooling will normally be 2 - 3 weeks Lead Time
Off Tool Samples will normally be 1 week Lead Time
Jigs & Fixtures can be then made up to cut the components from the moulded sheet. This operation is performed for low volume components.
CNC ROBOT TRIMMING
We can also set up Jigs & Fixtures so our CNC Robot Trimmer can trim components from the moulded sheet.
Vacuum Forming machines that have a variety of applications, utilising different plate sizes & but most importantly are driven by advanced CNC software to accurately adjust the individual heaters, the time, vacuum & ensure that the formed part is consistent every time.
There are three vacuum processes currently in use
