FILTERS FOR PLASTIC INJECTION MOLDING

    Nozzle flow 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 filters capitalizes on the unique capabilities of 3D printing to create additional benefit for the injection molder by integration of a static mixer or significant reduction of pressure drop and shear stress.

    Each filter is manufactured using Uddeholm AM Corrax Powder. 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.

    FEATURE COMPARISON

    • Pressure drop and shear stress can be influenced by many parameters (eg injection material, filler material, temperature, etc).
    • flow filter X should be selected if improved mixing performance is required in conjunction with high quality filtration.
    • flow filter V should be selected for high quality filtration with minimum overall pressure drop.
    • voestalpine flow filters are not recommended for glass fibre reinforced plastics.

    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 moulding nozzle filters.

    This configuration of in-line 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.
