    Sorted plastic granulates in various colors – versatile raw materials for customized plastic solutions in injection molding processes

    Thermoplastics – versatile, dimensionally stable, and cost-efficient

    We process a wide range of engineering thermoplastics, tailored to part function, load requirements, and production volume. Whether polyamide (PA), polypropylene (PP), ABS, POM, or glass fiber-reinforced plastics – our materials are used wherever precision, heat resistance, or mechanical strength is required.

    With many years of experience in material-specific design, we support our customers early in the project phase in selecting the most suitable material. This ensures plastic components that are both functionally effective and economically viable.

    Thermoplastic elastomers (TPE) in various colors – versatile materials for flexible plastic solutions

    Elastomers – flexible, durable, and functionally integrated

    For applications with specific requirements for sealing performance, grip, or flexural elasticity, we use thermoplastic elastomers (TPE) – often as hard-soft combinations in multi-component injection molding. These materials are ideal for sealing lips, flexible connectors, or ergonomic component zones.

    Our injection molding processes enable precise processing of elastomers in combination with rigid thermoplastic components – directly in the mold, without additional assembly. This results in functionally integrated parts offering high design flexibility and reliable performance.

    Injection Molding FAQ

    What is plastic injection molding?

    Plastic injection molding is a process in which a thermoplastic material is melted and injected under high pressure into a precisely manufactured mold. Once cooled, it forms a dimensionally stable plastic part with high accuracy – ideal for series production of technical components.

    Which plastics are suitable for injection molding?

    A wide range of thermoplastics is suitable for injection molding, including polypropylene (PP), polyamide (PA), polyoxymethylene (POM), ABS, and glass fiber-reinforced variants. Biobased or recycled plastics can also be processed under certain conditions.

    How much does it cost to produce a plastic part using injection molding?

    The cost of an injection-molded part depends on several factors, including material, part size, tool complexity, and production volume. While mold costs can be relatively high, unit costs are especially economical in series production thanks to the automated process. Share your project details with us – we’ll offer a cost-effective solution tailored to your needs.

    From what quantity is injection molding worthwhile?

    Injection molding is particularly efficient for medium to high production volumes. As a rule of thumb, the process becomes economically viable starting at around 1,000 to 5,000 parts – depending on the size of the component, mold cost, and required tolerances.

    What is the difference between 1K and 2K injection molding?

    In 1K injection molding, a single plastic material is used. In contrast, 2K injection molding (two-component molding) combines two different materials or colors in one process. The advantage of 2K technology lies in functional integration – for example, in hard-soft combinations, seals, or ergonomic surfaces – without additional assembly steps.

    What are the advantages of injection molding over other manufacturing methods?

    Injection molding enables cost-efficient mass production of complex components with high dimensional accuracy and repeatability. Compared to 3D printing or CNC machining, it offers significantly shorter cycle times, lower unit costs for larger quantities, and the ability to integrate function and design in a single part – e.g., with undercuts, clips, or built-in seals.

    Can biobased or recycled plastics be used in injection molding?

    Yes – many biobased or recycled thermoplastics can be processed using injection molding. They are especially suitable for sustainable series production, provided the requirements for strength and processability are met.

    How much does an injection mold cost?

    Injection mold costs vary depending on part complexity, number of cavities, and tolerance requirements. Prices for simple molds start in the low five-digit euro range. For complex shapes, multi-component tools, or high demands on cycle time and tool life, the price can be significantly higher.
