Plastic Injection Moulding

The core of our competences

Plastic injection moulding is the all-encompassing core competence of our diverse range of services. On our production area of more than 6,500 m2, we produce over 300 million pieces a year with more than 75 machines (5-1,000 t).

We manufacture items for you ranging from just a tenth of a gram to several kilograms and have hundreds of types of plastics in stock for this purpose. From the tried and tested PP/PE to special high-performance plastics as well as glass-fibre or mineral-fibre reinforced plastics, we can process almost all types of material. We manufacture in 1K and 2K processes.

Our many years of work for the automotive industry as well as for the medical and food industries are our proof of high competence and reliable delivery in serial production.

In addition to our various injection moulding processes, our plastic processing services also include component assembly, surface finishing, 3D printing, plastic welding, painting, printing and laser inscription.

We also support our customers in the plastic-compatible design of their components, which we then verify using 3D printed components.

Project Management

The key quality feature of any successful product development and launch is anticipatory and consistent project management, resulting in a product with maximum benefits.

Whether product launch, optimisation or further development: successful plastics solutions are created through an integrated project management system. From the 3D development of the components, to the prototype creation including extensive manufacturability analysis methods, we work together with you to develop a product that exactly meets your specifications and ideas.

We at Merschbrock Kunststoff Spritzguss GmbH are very familiar with the various standards and work according to the required, standardised processes of ISO 9001 2015 or IATF 16949 in the automotive sector. Years of experience in project management enable us to offer you the best possible service from the enquiry to beyond the series. In doing so, we strive for continuous improvements regarding the product and its manufacturing.

Surfaces as smooth as glass, as soft as leather or as shiny as metal. If the user no longer thinks of plastic when using the product, this could be due to the wide range of finishing options we offer.

Our quality concept extends far beyond the actual manufacturing process. By using a variety of finishing techniques, we transport your plastic product into new dimensions of visual and haptic possibilities. Modern high-gloss finishes, a leather look, soft-touch surfaces or chrome-plating of the components, all of this and more is possible. Lettering and logos on components enable high-quality individualisation.

Various plastic welding techniques enable us to join individually manufactured objects together and thus create assemblies. Plastic parts can be combined just as compactly and irrevocably with products made of metal and other materials.

Mould Technology

The mould is the heart of our production chain, because a plastic product can only ever be as good as the moulding tool The best results rely on anticipatory analysis methods, modern CNC systems and a great deal of experience.

On the basis of the latest 3D CAD/CAM systems, Merschbrock provides you with the complete development of new series tools. Furthermore, our own tool construction department is experienced in the maintenance and modification management of existing tools.

We also supply tools for small series and manufacture full-scale prototypes. This guarantees that no variable remains unknown until series production.

Automati­on Technology

In order to be able to deliver maximum quantities with minimum error rates in series production, automation that is perfectly designed for the product is our successfull recipe for consistent quality.

We have our own department for plant engineering, which specialises in developing fully automated production systems, including the associated quality monitoring, with the use of robots and camera systems.

Some of our highly effective equipment is patent-protected and ensures maximum benefit for our customers. But even where manual assembly is indispensable, we rely on a proven team of qualified employees.

Whether fully automated or hand-assembled: in both cases, the product arrives at your premises exactly as you need it.

Quality Management

The quality management system is the basis of our activities. From development to production to logistics, we achieve the desired results through targeted processes and coordinated resources.

For you as a customer, professional quality management is the decisive benchmark for the satisfaction of your expectations, at the end of which you have a product that reliably fulfils your specific criteria over the planned life cycle. With the latest measuring methods, qualified professionals and extensive certifications including regular audits, we convince with a quality management in which surprises have no place.
