Close-up injection moulding machine


Mould making for the production of complex plastic parts

Our plastic injection projects are a key part of the VWH portfolio. We develop and manufacture single-component or multi-component injection moulds for engineered individual parts or complex modules. Prototypes and series moulds can be trialled individually in our in-house technical centre. Mould proving can also be undertaken there on request. These conditions mean that small series can be implemented locally to short timeframes. In addition, we can also handle the storage of your unique moulds. As experienced experts in this material, we know precisely how important it is - especially on prototypes - to carry out precise data analysis in order to be able to make adjustments and improvements right at the start of the development phase. For that reason we produce detailed measurement and first sample test reports, making it easier to evaluate the data.

Advice and support for projects

We offer highest manufacturing competence for your products

However, our customer support already starts a stage earlier. Teams of experts at VWH support you during the design phase, helping the product towards efficient functionality. Thanks to years of experience in this area, we can spot vulnerabilities in the product immediately and can optimize them. The thinking that goes into VWH solutions means that component handling and the production process can be fully automated. That way, you optimize your internal production processes, saving time and costs.

Our versatility - your benefit!

There are many different processes and techniques in the field of plastic injection molding. Among other things, we work with the outsert or insert technique. When using the insert technique, the so-called inserts are inserted into the injection mold and subsequently overmolded with plastic. The advantages of the insert technology largely relate to the finished part properties, such as special metal threads in the plastic part, electrical conductivity of contacts, stiffening if necessary, wrapping as well as joining of metal parts by plastic and other possibilities. Insert technology proves its usefulness in case of a very high number of pieces and also in case of complicated inserts.

The outser technique works on a different principle. Here, elements made of plastic are applied to a carrier made of metal and fixed in place with the aid of undercuts and apertures. Direct gating avoids assembly costs and results in excellent positioning and bonding.

The combination of different materials, multi-component injection molding, is also no problem for us. Often the individual components differ in terms of thickness and strength. We combine hard components such as metal with a soft component by overmolding. Two hard materials can also be combined.
