Specializing in the application of PP/HDPE products, the system is credited for its high-speed but stable performance. Simultaneous actions of plasticizing, mold opening and ejecting enables fast cycle time.
Single injection cylinder structure leads to high precision and steady injection.
Optimized clamping unit with strengthened plates and cranes is the best choice for high-speed high-precision closure injection systems.
Operator-friendly Siemens S7-300 control functions fast remote diagnosis and software update.

Highly intelligent Balluff linear encoder from Germany realizes precise position control of injection, ejection and mold movements.
Closed-loop control of injection speed, pressure holding, backing pressure and filling pressure is available by adopting advanced Bosch servo valves.
Large capacity Rexroth Nitrogen accumulators from Germany provide instant high pressure during process and benefit energy saving.
Machine barrel and screw are made of wear-resistant alloy materials, which greatly expand life-span of the machine. Specially designed screws with check-ring valve contribute to excellent plasticizing performance. 

Main Features

PHY-F250 series injection system is specially designed for 2 to 5 gallon water barrel preform and oil barrel preform which can achieve fast-speed, high-efficiency and energy saving. The innovative outward toggle clamping structure and high capacity screw make it possible to produce performs which are heavy, thick, long and with wide-neck. It is suitable for up to 12 cavity mold. The machine has the following features
 Suitable for 2 to 5 gallon barrel preform with heavy weight, cavitation's range from 6 to 12

  250 tons clamping force, wide tie bar space, super-long mold open and eject stroke
  Special design screw leads to high efficient plasticizing, shot volume reaches 5696g per shot
  Fast & precision action control, packing is synchronized with plasticizing which highly shortens the cycle time
  Low molding stress guarantees the quality and perpendicularity of preform
  Automatic preform take-out robot and conveyor with vertical movement protects the preforms from falling and scratches

Hydraulic Unit

 Fast but stable running of the whole machine ensured by the specially designed hydraulic loop with multi-system compatibility.
 Large capacity Rexroth Nitrogen accumulators from Germany provide stable ample power for the machine as well as saving energy consumption.
 Advanced Bosch servo valves realize precise closed-loop control of injection speed, pressure holding, pressure backing and injection pressure.

Main Technical Data


Cap-Pressing Injection Molding Machine

PDMK-C24H cap compression molding machine is applicable for cap production from thermoforming plastics (PP, PE, etc.,), its rotating design ensures continuous cap production and no injection time, so yield rate is increased greatly.
The machine adopts continuous compression molding hydraulic press for plastic cap manufacturing via the extrusion of dry-blend granulated compounds (i.e. HDPE, PP), metering, pelleting and insertion in the cavities to mound it into the final shape. The capacity of the machine depends heavily on compound properties and the geometry of the manufactured caps.
