Getting plastic into shape

Injection molding

The injection molding process is predestined to bring PLASTIC into SHAPE. Many innovations in technical parts are based on combinations of the many different process variants or newly developed special processes. Common to all of them is the process sequence of preparing a plastic melt, injecting the melt into a closed cavity and cooling the material under mold constraint.

We use the extensive experience of our experts and the wide-range equipment of our technical center to examine every component of your injection molding process. We lighten your components, integrate functions cost-effectively and increase the robustness of your processes - making them more energy- and resource-efficient. Together with our experts in component and mold design, we work with you to realize a successful product. In addition to "getting plastics into shape" in line with the material and the process, we focus on the topics of functionalization, lightweight construction and process optimization using appropriate technologies and, above all, combining them.

Plastic innovatively shaped

Injection molding

In addition to other major plastics processing methods, injection molding is one of the most frequently used primary molding processes. The range of molded parts produced fully automatically and cost-efficiently by injection molding extends from simple mass products to complex, technical components and assemblies. Within this spectrum, we can support you with the most diverse issues.

2K injection molding

With 2K injection molding or multi-component injection molding, assemblies or components that previously existed individually can be integrated into a single part produced in a single manufacturing step. This enables functional integration in a smaller installation space and at lower cost. However, the process is anything but trivial, because the compatibility is important when joining two different melts. With our 2K injection molding machines and the matching 2K molds, we can answer any technical question and find the right combinations for you.

Foam injection molding

The main advantage of thermoplastic foam injection molding (TFIM) is the reduction in density and thus material. This also has a positive effect on the environment and economy. Density reduction can be achieved by chemical or physical foaming. Chemical foaming as an established process can be realized quickly and easily by metering a chemical blowing agent. For this purpose, a standard injection molding machine is used with minor machine modifications. Physical foaming offers even greater lightweighting potential compared with chemical foaming. Here, the blowing fluid requires special machine technology. The Cellmould® unit of the Battenfeld HM-MK 180/525H/350V is available for this purpose in the technical center of the KUZ. This machine can produce lightweight components in both 1K and 2K operation.

Combination injection molding reaction technology

With the technology platform for the process combination of thermoplastic and reaction injection molding, we bring together two of our technological core competencies to open up new potential for you. This process combination is based on the manufacturing principles of the classic multi-component injection molding process, whereby a reactive PUR or polyurea mixture is introduced into the mold cavity as the second component and bonds firmly with the freshly molded thermoplastic carrier during crosslinking. Visible and functional surfaces of three-dimensionally molded thermoplastic components can thus be efficiently finished with high-quality coatings. The thermoplastic components thus benefit from the noble high-gloss appearance with a good depth effect and from the insensitive surface properties of the crosslinked systems, right through to self-healing in the event of minor damage. As a result of the versatility of the PUR or polyurea systems used for this purpose, hardly any wishes remain unfulfilled.

Certified specialist for plastic injection molding

Due to the increasing shortage of skilled workers, companies are increasingly having to recruit employees from other areas or even specialist fields and qualify them for the tasks in their own company in the shortest possible time. The modular seminar provides compact basic knowledge of the injection molding process combined with comprehensive training on the injection molding machines. Participants thus acquire the ability to work consciously on the machines. With this in-service training in accordance with the qualification standard of the GKV/TecPart the graduates receive a qualification certificate that is classified below the vocational training as a process mechanic for plastics and rubber technology.

Use recycling cleverly!

The recycling of plastics is an essential part of closing material cycles in order to save significant amounts of fossil resources and waste. In times of raw material shortages and rising prices, it can therefore become an integral part of a sustainable and economically viable material supply. For practical implementation in injection molding operations, it is important to know the special requirements of the material and the processing technology. The seminar provides the necessary know-how to find climate-friendly, economically advantageous and process-reliable solutions adapted to the respective application.

Multi-component injection molding

Various special injection molding processes can be used to produce more complex components that not only offer cost benefits but also higher quality features compared to individual components, e.g. through increased functional integration. In the multi-component injection molding process, for example, composites can be created from several identical or different components. A key quality feature in the injection molding of two or more components is the adhesion between the different materials. For this reason, material selection and molded part design are particularly important. In this seminar, we will teach you the basics of multi-component injection molding technology and show you technical solutions.
