Windows update: latest in profiles technology
As with all extruded products, window profile quality can be improved through a combination of material, machinery and control technology. Sophisticated tooling can also play a key role.
Tecnoperfiles, a PVC profile extruder based in Argentina, is an existing Greiner Extrusion customer, and recently invested in a Red Tooling system for co-extrusion. It is Greiner’s first Red Tooling sale to South America. Red Tooling allowed Tecnoperfiles to produce
several new products, such as a new turn-and-tilt window system for a height of up to 3m (called Jumbo-Line), and two new sliding systems. Total capacity is around 5,000 tonnes/year, representing around 240,000 windows. “Red Tooling allowed us to optimise our
production and to drastically reduce our set-up and start- up times,” said Pablo Longhi, plant manager at Tecnoperfiles. PVC windows are still a relatively unknown quantity in Argentina – which Longhi says makes it difficult to explain their advantages to potential users. However, he says the market is beginning to

grow rapidly – as energy saving is an important issue. “We would like to switch our entire production
to Red Tooling immediately, but this process has to be done step by step,” he said. “The initial invest- ment is higher, but it’s worth it because of the cost-effectiveness.”
Automatic control Greiner has also developed its Flow Matic technol- ogy, which automatically controls the dimensions of profile sections. Based on its earlier Flow Control technology, it
controls temperature and melt flow directly in the die by heating or cooling. It measures the filling level of individual profile sections and – with the Flow Control die function – builds up an automatic control loop. “The reaction takes place in a few seconds,” said the company. “This results in constant profile measurements even when process fluctuations occur.”
Separate to this, Greiner adds that its Layer Coex September 2019 | PIPE & PROFILE EXTRUSION 21
