Quick Mold Change Systems for Plastic Injection Machine


    This combination does not exist.


    The application of magnetic chucks in plastic injection molding machines can significantly enhance production efficiency and processing stability. Firstly, magnetic chucks can quickly and securely fix molds onto the worktable. Even during high-speed injection and mold opening/closing processes, they maintain precise mold positioning, preventing shifting or vibration and ensuring consistent product dimensions and yield. Secondly, electro-permanent magnetic chucks enable rapid mold adsorption and release, shortening mold changeover time. This is especially suitable for multi-variety, small-batch production, effectively improving machine utilization. Additionally, the clamping process with magnetic chucks eliminates the need for traditional bolts or clamps, reducing manual operation and safety risks, making the operation more convenient and flexible. Furthermore, magnetic chucks do not generate high temperatures or cause deformation during adsorption, avoiding thermal expansion that could affect mold precision and improving injection molding quality. Finally, magnetic chucks are energy-efficient, maintaining magnetic force after magnetization without continuous power supply, reducing energy consumption and extending equipment lifespan. Overall, magnetic chucks not only improve mold changeover efficiency and processing accuracy for injection molding machines but also optimize operational workflow and safety, making them an ideal solution for mold fixation in modern plastic injection production.  

    Feature

    • Electro-Permanent Magnetic system: 2~10 seconds control for power ON & OFF. No power supply required to keep the magnetic chuck on, Safety in case of power failure. Never get temperatures and deformation mold.
    • Magnetic force depends on the mold needs, with 3 sizes pole can choose.
    • Magnetic chuck is dual poles (N/S poles), no magnetize machine frame and equipment relative parts.
    • The clamping force is distributed consistently along the whole mold surface reduce product burs and increase mold duration.
    • Significantly reduce mold setting time up to 70%; shorten delivery time, increase efficiency and productivity.
    • Improve the strength and parallelism of machine movable/ stationary plate and machine frame.
    • Increase clamping area by 20%, perform clamping on all molds shapes, reduce burrs and the amount of mold maintenance.
    • Can be used with a working temperature up to 120℃, higher product safety.
    • No oil working environment, stable quality, applying for high working specification of germfree/dustfree.

    Specification

    EEPM-PIM designed for different mold thickness. Specify the mold to be Large, Medium and 
    Small sizes, make 3 poles size. Different pole sizes have different magnetic field height to ensure 
    mold clamping safety.
