Injection molding is what Rompa Group has been famous for for many years. It might be one of our specialties but in the end it is all about the combination of services and technologies. This makes it possible to deliver our clients the best possible service. Rompa Group has many different materials for injection molding at their disposal. Whether it's thermoplastics like PET, ABS, polyethene, PC, polystyrene and polypropene, or engineering plastics like Ultem, PSU, PPU and PEI. Besides the materials we also use different types of injection molding technologies:
Thin-walled injection molding
The demand for producing smaller and lighter parts or cases is increasing every year. Thin-walled injection molding is mostly seen in electronics where some parts have a wall thickness less than 1 mm. In the automotive industry we talk about a 2 mm wall thickness for their parts. Producing thin-walled items makes it necessary to implement process changes, such as a higher pressures and speed, but also faster cooling times. There are many considerations to take into account when producing a thin-walled item.
High-precision injection moulding
A highly technical process that requires the usage of precision molds and machines. Rompa Group uses this technology to produce complex geometric parts that are being used for high precision industrial applications.
2K injection molding
‘Two shot’ injection molding, also known as 2k injection molding, is a manufacturing technique of combining two different polymers or two different colors into one plastic part. The 2k injection molding machine gives Rompa Group the possibility to produce one part made of two different colors or materials. For example, a combination of soft and hard material like your toothbrush which is made with a soft grip.

Rompa Group has the ability to produce parts with an additional technology called overmolding. During this molding process we use several molds instead of just one to create a finished product. This gives the possibility to combine different materials and shapes.

For in-mold labelling we use our injection molding technique. Instead of having to glue a label to a product, the label becomes integrated with the product. The IML technology was originally designed for blow molding, but with the use of injection molding this process became a whole lot more efficient.
