Multi-component injection moulding

Tools that process different plastics are efficient and functional. But it's precisely these complex components that require a lot of know-how and the best possible precision. Get in touch with Hofmann Impulsgeber if you're looking for a competent partner in multi-component injection moulding.

Variotherm®

In research and development, we're constantly creating new ideas. One result of this work: Variotherm®. In contrast to other technologies, this injection moulding method involves alternating heating and cooling of the injection mould tool. This process makes a surface appearance possible that doesn't require costly reworking, such as painting.

Gas/water injection

Gas/water injection is particularly suitable for thick-walled or hollow components. With this technology, we guarantee the most cost-effective solution. Besides thick-walled components (e.g. handles, pedals etc.), gas and water injection is also suitable for media lines made of plastic (e.g. moulded pipes for air conditioning systems and cooling water).

ColorForm® / Direct Coating / Clearmelt

ColorForm® is a technology for the production of components with high-quality premium surfaces at low costs. ColorForm® technology makes it possible to replace classic painting processes.

SkinForm® / Direct Skinning

SkinForm® technology works on the same principle, using foamed polyurethane. This enables things such as the production of components with a soft-touch surface.

Stack/tandem injection moulding

Stack or tandem injection moulding is particularly suitable for large, flat parts and high volumes. By arranging the components one behind the other in two main stacks, several items can be produced with only a slightly higher clamping force compared to one main stack. Tandem injection moulding also offers the advantage that items of different sizes can be produced with the same material. This allows the customer to save up to 40% in costs.

IMD film and fabric insert moulding

IMD and film insert moulding enables the comfortable and time-efficient finishing of complex curved components with symbols, transmitted light technology and multi-coloured flat decorations during the injection moulding process. Insert moulding of textiles is also a cost-effective alternative to the labour-intensive lamination of plastic parts.

Injection-compression moulding

In contrast to conventional injection moulding, injection-compression moulding involves injection into a slightly open tool, and the cavity does not close until the solidification process. This compression moulding enables a more direct and uniform force transfer to the plastic melt. As a result, there is less distortion and residual stress.

Assembly injection moulding

Assembly injection moulding is a particularly cost-effective injection moulding technology. It directly combines joining and assembly processes during injection moulding. This means that additional components can be injected directly without any welding or gluing, enabling the flexible or fixed connection of several components.

Insert injection moulding

With insert technology moulds, prefabricated metal parts are inserted and overmoulded. The combination of metal and plastic creates hybrid components that combine the advantages of both materials.
