voestalpine flow filter X

Nozzle filters are used to prevent contamination from the plastic melt causing blockages or interruptions to the injection process. These contaminates can cause damage to hot runner systems resulting in extended downtime and increased maintenance costs. The design of the voestalpine flow filter X capitalizes on the unique capabilities of 3D printing to integrate a static mixer and filter into a standard form factor, delivering improved performance over traditional injection molding nozzle filters. This configuration of inline static mixer and filter helps prevent feed blockages caused by material impurities, such as those encountered when processing recycled materials and delivers superior mixing properties when using additives. The unique material flow design of the flow filter results in a significant reduction in pressure drop typically associated with traditional injection molding nozzle filters, giving additional benefits such as reduce machines wear and energy consumption. Each filter is manufactured using  special raw material by our brands. This dedicated Plastic Injection Mold steel has been specifically design for Additive Manufacturing applications, it properties ensure the highest possible molding performance due to its increased corrosion and wear resistance.
