FLOW.CONTROL guarantees functional dimensions and minimises material use during the extrusion process.

With FLOW.CONTROL, an innovation of the Greiner Extrusion Group, the profile extrusion process can be sustainably improved. By means of melt flow control, individual profile sections are slowed-down or sped-up using cold or hot air. This action guarantees functional dimension accuracy while providing considerable material savings. The material flow reacts within minutes, usability is improved, and all settings can be reproduced. With the additional control option, the line flexibility is also increased, and reaction and/or intervention times upon environmental fluctuations are significantly lowered. FLOW.CONTROL delivers the highest process safety, shortening start-up times, and reducing rejects and protracted production cycles. FLOW.CONTROL can be retrofitted to most of our nozzle designs.

FLOW.CONTROL for new pool cover made of PVC and polycarbonate from PRIMO

PRIMO develops, manufactures and sells extruded plastic profiles for products of many industries such as construction, electronics, energy, furniture, shipping, medical technology, lighting, offshore, power plants, transportation, household appliances, windows and doors, and many more.

The current development of PRIMO, a system for pool covers made of PVC and polycarbonate, imposes high functional and design requirements. For the rolling cover profiles to interleave smoothly, they must provide exact dimensional accuracy, especially with respect to hooks. FLOW-CONTROL ensures that such necessary functional dimensions are provided by controlling the relevant profile sections.

"With certain profiles, FLOW.CONTROL is indispensable to meet the high requirements imposed on profile geometries. What is more, FLOW.CONTROL drives total profile costs down via considerable material savings, lower reject volume, and shortened start-up times. FLOW.CONTROL is an outstanding system to monitor the extrusion process. This allows us to ensure efficient production for our customers. Given the notable savings achieved, PRIMO will continue to invest in further FLOW.CONTROL systems next year. Thanks to our material savings, we can also offer environmentally friendly and resource-saving solutions", says Harald Möllenkamp, Operations Manager at PRIMO.
