  • 2. Features of 550 Ton injection mold machines for plastic 

  • -550 ton injection machine clamping unit features-

    • Enough space for upgrade and retrofits

      It not only meets the customers’ requirements at the moment,

      but also offers more possibility in the further production.


      European type ejector structure

      It provides larger space and easy for maintenance.


      Upgraded parts

      Graphite-copper bushes and slider are used on tie-bar, ejector and movable platen. It ensures

      fast and precise mold closing and opening.


      Better designed mechanical structure and

      toggle system

      It shorts the production cycle time and improves production



      Enormous space between tie-bars

      It is suitable for larger molds and multi-cavity molds necessarily.


      Longer and wider guide length & higher precision

      It improves mold work-life and product quality.


      High rigidity mechanical system

      It protects the mold and extends machines’ lifetime.

  • -550 ton plastic press injection unit features-

    • ■ Imported high quality SKD61 material

      The screw tip, checking ring and trap ring are made of imported

      high quality SKD61 material. And we provide various choices

      for screws to meet different plastic materials and special [processing

      injection mold needs.


      ■ No welding design

      Injection unit steel pipes adopt pipe fitting to connect. No welding

      design ensures convenient maintenance and after-service.

      ■ Upturning designed nozzle cover

      It makes the production and maintenance much easier.


      ■ Dual carriage cylinders

      It improves a better injection precision.

      ■ Dual precise linear guide rails

      Full supported injection unit with dual precise linear guide rails

      ensures the best precision and fast start speed.

  • -550 Ton plastic injection machine electric system and hydraulic loop features-

    •  Servomotor system

      All machines are standard equipped with precise and energy

      saving servomotor system. It could save energy as much as

      20%-80% compared with traditional injection machine.

        German DIN standard fittings

      German DIN standard fittings with seal are widely used in

      hydraulic unit. G screw thread style plug avoids oil pollution.

       Visible and dischargeable design

      Visible and dischargeable oil tank and modular adaptor valve

      blocks make it more convenient to hydraulic circuit maintenance

      and function upgrade.

      ■ Water proof rubber seal

      It is used on electric cabinet and improve the machines’ safety.

       Modernized network

      Modernized network management function is available for our

      customers. It could easily share data with MES system.

       CE safety standard

      The programs are designed according to CE safety standard


      The controllers are all color screen from reliable cooperators.

      The multi-language controller is available. Better cooperation, faster speed.
