Prototypes and small series with modern injection molding technologies

Whether you're interested in prototype injection molding or a small series, our special injection molding processes can be easily applied to both. Our special processes offer a wide range of options for designing your components even more efficiently. For example, by combining multiple materials or overmolding metal inserts, several tasks can be combined in a single component. This saves time and money when reusing the components. The following special processes are among our strengths.

Injection molding special processes

Two- and multi-component injection molding
Learn more
Multi-component injection molding produces components made of different materials, such as hard components with a sealed geometry. A separate mold is manufactured for each component. After the first component is molded, it is inserted into additional molds and overmolded.

Insert technology
Learn more
With insert technology, inserts are placed into the injection mold and overmolded with plastic. These inserts are typically threaded bushings, contacts, sheets, or coils. Overmolded parts such as magnets or circuit boards are also possible.

Outsert technique
Learn more
In the outsert technique, plastic elements are sprayed onto a metal carrier and anchored via undercuts or openings.

Micro injection molding
Learn more
Micro injection molding refers to the production of injection-molded components with a shot weight of less than one gram.

In-mold process
Learn more
In the in-mold process, also known as in-mold labeling, foils, fabrics, or paper are inserted into the mold and back-injected with plastic. This creates sophisticated surfaces in a single step.

Gears
Learn more
The production of gears places special demands on plastic injection molding. Due to the concentricity tolerances typical of gears, the injection molding concept must be designed to accommodate these specific requirements. The production of precision gears is one of our specialties.

Cable/hose overmolding
Learn more
When overmolding cables or hoses, sealing the cable/hose presents a challenge. These are usually subject to strong tolerance fluctuations, so a special sealing concept is used here.

TSG procedure
Learn more
By adding blowing agents, a foam structure is created in the component core. This process is typically used for wall thicknesses between 4 and 20 mm. The process is used to provide thick-walled components with a foam core, thus preventing sink marks caused by material accumulation.

Melt core injection molding
Learn more
In the melt core process, a core made of a low-melting metal is inserted into the mold and overmolded. The metal core is then melted in a heating bath. This process is used to create undercuts or cavities that cannot be created with demoldable cores.
