Getting plastic into shape

Injection molding

The ART of shaping the MATERIAL is predominantly realized with the injection molding process. 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.

The KUZ draws on the extensive experience of its experts and the wide-ranging equipment of its technical center to examine every component of your injection molding process. We make your components lighter, integrate functions cost-effectively and make your processes more robust, energy and resource efficient. Together with 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 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 2C 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 following criteria are important when joining two different melts, which we determine for you in practice. 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 molding (TSG) 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 1C and 2C 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.

Multi-component injection molding

Various special injection molding processes can be used to produce more complex components that not only offer cost advantages but also higher-quality features compared with individual components, e.g. through increased functional integration. For example, multi-component injection molding can produce composites from several components of the same or different types. 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 molding design are particularly important. In this seminar, we will teach you the basics of multicomponent injection molding technology and demonstrate technical approaches to solutions.
