Profile extrusion machinery goes down to Red Line

Red Com composite for profile line

Austrian company Greiner Extrusion has a revolutionary new generation of profile extrusion machinery called Red Line, which includes the Red Line system and Red Tooling.

Greiner engineers reviewed all functions of previous technology and re-engineered with the goal to increase productivity, minimise energy and improve quality for extrusion profile manufacturers.

The Red Line system provides for maximum possible savings in terms of energy and water consumption, securing process reliability and improved handling at the same time.

The Red Line extrusion downstream system consists of Red Cal calibration table and the Red Com haul-off combination unit.

Water consumption is conserved by up to 50 per cent with the closed water circuit system that uses the water twice. Firstly, it is used for calibration – as the water does not flow freely on the calibration table, there is no contamination.

Secondly, the water is reused for the cooling tanks. An internal water circuit with an automatic filter system filters the water and automatically backwash filters removing dirt particles.

The Greiner Energy Saving System (GESS) incorporates a demand actuated control solution that controls individual vacuum and water pumps along with side channel compressors, saving up to 90 percent of energy costs. It also reduces the sound levels by 50 percent to only 10dB.

A guidance system on both sides of the haul-off provides for accurate parallel alignment, ensuring no tension is exerted on the profile. The significantly wider pads can be changed without tools and retrofitting time is reduced by half.

The Red Cut cutting unit provides for the exact cutting of profiles at variable cutting speeds utilizing a rapid tool-less knife changeover enabling tool changeover ‘onthefly’. The PLC control system allows for centralised operation of all functions, data logging, monitoring and evaluation and control of the knife heating.

Red Tooling incorporates tooling features for the toughest demands. Utilizing Flow Control, profile sections can be slowed down or accelerated, variably and accurately utilizing cold or hot air without affecting adjacent solid sections. The post dry calibrator (PDC) improves process stability, quality fluctuations are minimised and roller templates improve surface quality of the profile, resulting in up to 90 percent fewer scratches.

A single multi-pin connector between the Red Line equipment and the extruder eliminates wiring and ensures fast connect/ disconnect eliminating the potential for errors. The modular design also allows customers to retrofit parts of the Red Line into existing lines if required.

Greiner Extrusion is represented in Oceania by HBM Plastics Technologies.
