Some of the latest innovations in plastic mould operations are increasingly utilising the concepts of two-component and two-colour type moulds. These can be seen, for example, in car headlight assemblies, and an ever-increasing range of products.

During moulding, the first material is injected into the die, which is then opened, rotated 180 degrees and closed again before a second material is injected. This could be a different colour or type of material depending on the component being manufactured. By producing complex components in this way, the end-product is completed on a single press without any further tool changes.

If one were to set such a mould tool on a traditional spotting press, it would be necessary to simulate the production process with a first phase in the 0-degree position and a rotation would be required for the second operation. With standard technology, this would entail removal of the tool, rotating it 180 degrees by hand with a crane or other device and repositioning back in the traditional spotting press.

In order to reduce the time and effort required for such checks, Millutensil said it has designed a special tilting table that permits the mould to be presented in the two positions of zero and 180 degrees.

The supplier said one of its constructional innovations is the reason that this system is completely integrated. It is said to include full control via drives through the rotation operation, with full monitoring of the positions.

Moreover, it uses the same standard press, reducing the time wasted on procedures, which ensures maximum flexibility, the company said.
