Vacuum forming is the heart of our production. More than 25 years of experience in processing thermoplastic materials make us your ideal partner. 6 vacuum forming machines produce parts up to a maximum blank surface area of 2,500 x 1,250 mm with a height of up to 600 mm. In this way, small parts can be produced in large quantities on multiple moulds just as quickly and flexibly as individual parts for trade-fairs.

Step 1:

Heating panels heat the plastic sheet until the material becomes thermoplastic. During the heating phase, the material is constantly monitored by radiation pyrometers.

Step 2:

After the heating phase, the heating panels move back. The sealed mould chamber is filled with compressed air. The labile material yields to the pressure and is pre-stretched homogeneously. The aluminium mould then moves into the hemisphere.

Step 3:

As soon as the mould is in position, the air between the material and mould is extracted by vacuum so that the material assumes exactly the shape of the mould. Ventilators cool the material down again (monitored by radiation pyrometers), the clamping frame opens and the moulding can be removed. The production process is under complete control at all times. The system warrants the ideal material temperature.

The vacuum moulded parts undergo post-processing on modern 5-axis CNC milling machines with a maximum machining width of 3,000 x 2,500 mm and 800 mm in height. This warrants reproducible part trimming from the first to the last part, also for follow-up orders. We can produce the necessary moulds quickly and economically in our own toolroom. We can also mill 2-dimensional parts such as frames, lettering or coverings, working to your specifications. Furthermore, parts produced elsewhere by injection moulding or rotation sintering can also be trimmed to the right size on our machines on a job-order basis.

Our fully automatic bending machine can be used to produce parts with a length of up to 3,000 mm. Up to 5 bends are produced fully automatically according to the program. The next bending seam is already being heated up during the cooling phase. This permits particularly economical production particularly for box construction. Contact-free heating rails with upper and lower heating permit the production of small radii, while a heating sword in the upper heating circuit produces sharp angles with contact heating. The bent sheets are then brought to hot gas, butt welding or extruder welding machines to produce the finished boxes. This procedure is suitable both for individual parts and also for large series.
The Siemens S7 CNC control warrants reproducible production from the first to the x^th part.

Our assembly workstations are equipped with all the necessary manual tools to supply you with a component that can be used immediately. On the one hand, this includes additional procedures such as gluing, welding and hot embossing, and also on the other hand the actual finishing of a product by fitting add-on parts provided by the customer, for example. The services we provide extend right through to the product ready for sale.
