Thermoforming is particularly suitable for quickly creating preliminary functional models of plastic during container production. The outer geometry is made from two thermoformed half shells – inner ribs, retainers, connectors and filler neck thread are produced on CNC machines and welded into or onto the shells before the shells are welded together. The thermoforming moulds are made from hard foam or aluminium, depending on the quantity required, and finished using 3D CNC milling machines. Transparent containers can also be made of PC or PET for inclined position and flow tests.

Average production time
- Thermoformed parts are generally completed within 3 to 4 weeks of receipt of the 3D data.
Applications
- Pressure and temperature cycle tests.
- They can be used for initial driving tests under real conditions.
Materials
- Preferred materials are polyethylene (PE), polypropylene (PP), chlorinated polypropylene (PPC) and the heat-resistant polyvinylidene fluoride (PVDF) (Tmax 160° C).
