    Blow Molding

    Blow molding is a process for manufacturing hollow parts from thermoplastic polymers, and includes two steps: using extrusion or conventional injection molding, first a so-called preform is produced which is then blown into a hollow part. Blow-moldable thermoplastics include e.g. polyamides and POM.


    In casting (potting process), components are created from reaction mixtures such as polyurethanes and dosed into open or closed molds.


    In extrusion (extrusion molding) foils, monofilaments or profiles are created by squeezing thermoplastic plastics through a die applying pressure. Frequently used plastics include polyamide, PBT; POM as well as TPU.

    Fiber Spinning

    How are continuous filaments created from polymer melt? When spinning polyamide melts, individual filaments are created, which are joined and stretched into yarns.

    Filament Winding

    For manufacturing the plastics hollow parts according to the (filament) winding process, reinforcing fibers which are impregnated with resin - such as polyurethane or epoxy - are rolled onto a core.


    Foams can easily be manufactured from polyurethanes (PUR) using water or physical propellants. The result is a great variety of products: open- or closed-cell, soft or hard foams.

    Injection Molding

    Injection molding is the most widely used processing method for thermoplastic polymers such as polyamide (PA), PBT or polyarylsulfone (e.g. PESU). Injection molding is used whenever cost-effective manufacturing of plastic components in high numbers is required.

    Particle Foaming

    Foam particles such as EPS, and EPP can be processed into molded foam parts in a molding machine. Thereby, foam pellets are blown into forms and fused together or sintered using super-heated steam . The molded parts can be removed after a cooling and stabilizing period.


    Pultruding or continuous casting serve the manufacture of fiber-reinforced continuous profiles from plastic. Frequently, polyurethanes or other duromers are used in pultrusion.

    Reaction Injection Molding

    Reaction Injection Molding (RIM) was developed for polyurethane foam components. Immediately after mixing, the reactive, two-component mixture is injected into the molding where the plastic hardens rapidly.
