Available solutions

BARRIER SCREW

Special screw design (barrier geometry) provides the ability to better control the temperature during plasticizing the melt and plastic mass - including faster and more precise material feeding.

  • Suitable for packaging and transparent products
  • Barrier design reduces plasticizing time by up to 40%
  • Barrier geometry allows for reduced backpressure during plasticization
  • Additional mixing zones are also used in the production of pigmented plastics to speed up their homogenization
  • Chemical resistant
  • Energy efficient
  • Not suitable for use with fiberglass and other abrasive additives
  • Not suitable for the production of technical parts

RECOMMENDED FOR PROCESSING: PP | PE | PC | PET | ABS | PMMA

SCREW - TYPE H (SINGLE FLIGHT)

Basic geometry, allowing wide application in processing different types of plastics.

  • Conventional three-zone geometry
  • Excellent plasticizing parameters
  • Suitable for processing of materials with fiberglass
  • Suitable for processing materials with flame retardant additives
  • Low compression ratio

RECOMMENDED FOR PROCESSING: PA | PPS | LCP | PP | ABS | PE | PS | PBT | PC | PMMA

MIXING SCREW

Universal for all types of materials. Additional mixing zone at the end of the screw improves material homogenization.

  • Improvement of production quality
  • Good melting quality of the plastic mass
  • Pressure reduction
  • Improved homogenization/mixing
  • Energy efficiency
  • Not suitable for long glass fibre material

RECOMMENDED FOR PROCESSING: PMMA | PET | PA | POM | PC | PE | ABS | PPS
