PRE-MIXING (MIXING)
KOCH offers flexible solutions for mixing and dosing plastics that make your company more economical.
KOCH Pre-Mixers mix plastics, eg granulates, ground material or free-flowing powder with masterbatch or additives.
The homogeneous mixture is the basis for further processing in injection moulding, extrusion or blow moulding.

You can add a hopper filler to fully automate the process.

Pre-Mixers for injection molding machines:

  • Pre-Mixer Type KK
    • for throughputs up to 25 kg/h and bulkhead weights up to 0.2 kg
    • The KK mixer is almost ideal for mixing plastic materials with powder or masterbatch on smaller injection molding machines.
    • The mixer has an inlet for the main material and an attachment for a dosing station.
  • Pre-Mixer Type G
    • Ideal for throughputs up to 70 kg/h and bulkhead weights up to 0.9 kg
    • The G mixer is the bigger brother of the KK mixer and has an attachment for the main material and two attachments for dosing stations. The plastic material and all dosed excipients are homogeneously mixed in the G mixer.
    • Up to four different material components, eg virgin material, regranulated material, masterbatch and additive can be processed.
  • Pre-Mixer Type V
    • Ideal for throughputs up to 250 kg/h and shot weights up to 4,000 g
    • Dimensioned for high machine throughputs, these mixers cut a good figure in large injection molding machines: homogeneous mixing of up to 250 kg of plastic per hour is no problem!
    • The large mixers of this series are made of V2A stainless steel. In combination with the right transport units and up to three dosing stations, the masterbatch, free-flowing powder and new goods or ground materials are well mixed and processed.

Pre-Mixers for extruders and blow molding machines:

  • Pre-Mixer Type Gx
    • For machine throughputs up to 60 kg/h
    • The premixer type Gx is optimized for use in extrusion and blow molding systems. The material is batched into the mixer and mixed homogeneously before processing.
    • The pre-mixer has four attachments for dosing stations or slides for batch dosing. If the fill level falls below a certain level, all stations dose an accurately adjustable amount into the mixer.
    • So even with uneven machine output, the color will always remain constant.
  • Pre-Mixer Type Vx
    • Premixer for machine throughputs up to 500 kg/h
    • A homogeneous mixing of the batch-dosed material guarantees consistent results in the film extrusion.
    • The premixer is available in different sizes; the main body is made of high quality cast aluminum ingot or V2A stainless steel, depending on the type and need.
    • In addition, dosing units for masterbatch, ground material or good free-flowing powder are available.
  • Mixers for different throughput capacities
  • Color stays constant
  • flexible solutions for mixing and dosing plastics that make your business more economical.
