Promix Solutions will be presenting suitable solutions for mixing, foaming and cooling plastic melts at Fakuma. The focus will also be on the topic of savings. With these solutions, users can save raw materials and reduce their CO2<\/sub>-footprint.<\/strong><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

In plastics processing, the material share accounts for 80 per cent of CO2<\/sub>-footprints. With the Promix Microcell Technology polymer by adding environmentally friendly atmospheric gases (N2<\/sub> and CO2<\/sub>) creates a microcellular foam structure<\/strong>. This reduces the product weight by 20 - 50 per cent, which leads to savings in raw materials. This not only reduces production costs and protects the environment.<\/p>

Promix Microcell Technology is suitable for Foils, sheets, foam core and corrugated tubes as well as profiles, cable sheathing, blow moulds and blown films<\/strong>. Promix<\/a> shows on the Fakuma<\/a> relevant key components and provides information on possibilities within the specific fields of application. Promix Microcell Technology can be used for almost all raw materials. The technology is available both for newly planned extrusion lines and as a retrofit solution.<\/p>

The company has further optimised its technology. This allows injection moulding processes to be improved even further and maximum cost savings to be made. Promix mixing nozzles and static mixers ensure Improved melt homogeneity immediately upstream of the moulding tool<\/strong>. This allows additives to be distributed better and eliminates unwanted colour streaks. Thanks to the improved colour distribution, the masterbatch concentration can also be reduced by 20 - 40 percent in most cases, which reduces consumption in the long term.<\/p>

The installation of a mixing nozzle enlarges the process window and allows the process parameters to be adjusted. As a significant part of the mixing task is now performed by the mixing nozzle, the Back pressure reduced<\/strong> be used. This makes the Gearbox is protected and the service life of the worm increases<\/strong>. Depending on the component, the lower back pressure shortens the melting time and therefore also the cycle time, which has a positive effect on productivity. Thanks to a more homogeneous temperature profile, the melt temperature can generally be reduced by 10 - 20 \u00b0C, which favours a shorter cooling time and therefore an energy-saving injection moulding process.\u00a0<\/p>
