The continuously operating ERF melt filters are suitable to process low to highly contaminated plastic melts. They filter high levels of contaminations like paper, aluminum, wood, silicone and plastics, melting at higher temperatures. The fully enclosed system includes constant melt pressure, very strong process reliability, extremely low melt loss and very short contaminant retention times.
Typical applications of the ERF melt filters are the recycling as well as sheet and profile extrusion. They fit into any extrusion line and processes a huge number of plastics like LDPE, HDPE, PS, ABS, PP, POM etc..
According to their small footprint the ERF melt filters require very small space for installation. The available three different sizes ERF-200, ERF-250 and ERF-500 allow throughput capacities up to 6.000 kg/h.
The continuously operating ECO melt filters are derived from the long time proven technology of the ERF melt filter. With their permanently rotating filter screen they are based on the same function principle.
The ECO melt filters are designed for the use in compounding, film and sheet lines. Due to a very efficient and simultaneously pressure and process constant filtration, especially for gels and agglomerates in virgin material, spots are reduced in the final product and therefore the quality is pretty much improved and off spec or waste production is reduced.
Next to the filtration of polyolefins, the ECO melt filters are suited also for low viscous materials like PET and PA. They are successfully used for the production of thermoforming sheet and strapping band from 100% PET bottle flakes or PET fines.
With a very compact design, ECO melt filters can operate extreme long times for weeks or month. Designed for contamination contents up to 1,5% weight, the melts filters are available in two sizes: ECO-200 for throughput capacities of up to 1.000 kg/h and ECO-250 for up to 2.500 kg/h.
Product category: Injection moulding machines above 10000 kN clamping force
srm - Injection Molding Machines
srm injection molding machines require significantly less clamping forces than conventional equipment for the same shot volumes and identical cycle times.
Thanks to the innovative two-stage injection unit srm injection molding machines can process both virgin and recycled material as well as mixed plastics. Overall, the srm machines achieves high performance with significantly less power – its smaller drives use less electricity and take up less space.
srm injection molding machines are up to 40% shorter than conventional models leading to a comparatively small overall footprint. With their twin-platen design, the srm line has also a large opening stroke with no tie bars in the way which leads to less complex part removal and more straightforward mold changes.
The srm injection molding machines are available with clamping forces up to 30.000kN and shot volumes up to 160.000cm3 and are the preferred solution for the production of plastic pallets, fittings, manholes and waste water systems.
Ettlinger Kunststoffmaschinen GmbH was founded in 1983 and is today a global player. The German company has its headquarters in Königsbrunn, not far from Augsburg. Its core competency is the development and manufacture of injection molding machines and high performance melt filters.
Ettlinger injection molding machines are optimized for the production of polymer moldings up to 100 kilograms in weight such as plastic pallets, fittings, or manholes. An ingenious modular system allows affordable solutions and machine concepts to be offered for a wide range of applications.
On the melt filtration side Ettlinger makes high performance melt filters for continuous filtration of low to heavily contaminated feedstocks. The ERF melt filters are especially used for recycling, even high contaminants like paper, aluminum, wood, silicones, or high-melting polymer composites can be reliable removed from all standard polymer materials whereas the ECO melt filters are primarily meant to be used for compounding and film applications. ECO melt filters removes gels and agglomerates also from virgin materials thus reducing spots of the final product which results in better film quality and simultaneous increasing lifetimes. In addition ECO melt filters are also used for processing of PET and PA.
