WPC profiles

Ranging from flooring and decking to door frames - due to the good price/performance ratio wood plastic composite (WPC) attracts the attention of lots of areas.

Whatever you want to implement Greiner Extrusion is your partner. In cooperation with customers, partners, national and international research establishments Greiner Extrusion developed technologies for numerous applications and has meanwhile acquired extensive experience in the provision of turn key solutions.

Various materials of natural or wood fibers with plastics are processed into a compound. The most frequently used compounds are wood/PVC and wood/ PP featuring a share of natural fiber additive of up to 70%. Other additives such as UV protective agents, color pigments, flame retardants, or also biocides against fungal infestation are incorporated.


Your benefits:

  • Optimum handling
  • Easy to use
  • Long running performance
  • High process stability
  • High profile quality


Lowest material usage. Most precise profile geometry.

With FLOW.CONTROL you can improve your production ongoingly. Through control of the melt flow, individual profile sections are decelerated or accelerated selectively with cold or hot air. This results in constant profile dimensions and production near the lowest profile weight tolerance.

Your Benefits

  • Exact profile geometries
  • Lower material costs
  • Highest repeatability
  • Faster start-up
  • Lower production costs

With FLOW.MATIC – the evolution of FLOW.CONTROL – you can now ensure constant functional dimensions of the profile sections fully automatic and within seconds.

Savings due to material savings and lower scrap rate:
FLOW.CONTROL: ~ 27.000 € p. a.
FLOW.MATIC: ~ 48.000 € p. a. (considering personnel costs )
Example window frame: 1,2 kg/m, 5000 hrs/a production time, 1,2 €/kg material cost, 350 kg/hr output




Air support control

Providing ventilation of inner chambers.

The supporting air control makes ventilation of the inner chamber safe. The controlled air supply secures the geometry of the inner chambers, thus avoiding scrap.

Your Benefits

  • Automatic ventilation of the inner chambers
  • Secures the geometry of the inner chambers
  • Avoiding of rejects
  • Automatic deviation signal

Savings: ~ 7,000 € p. a.
Example window frame: 1,2 kg/m, 5000 hrs/a production time, 1,2 €/kg material cost, 350 kg/hr output

Avoid deposits in the dry calibration.

KEEP.CLEAN Unit removes dirt efficiently, before potentially affecting the extrusion die.

Your Benefits

  • Prevents contamination in the vacuum slots during the first dry calibration process
  • Significantly prolongs production uptime between cleaning processes
  • Available for existing tooling systems as a retrofitting option at a reasonable price

You can achive about a 25 % longer net production time / year (depending on the formulation, output, number of tool replacements, etc.
