INJECTION UNIT
High rigidity, Stability, Convenience, and modularization
- High rigidity: Bench-type injection unit has a high rigidity. This design eliminates all the hard abrasion between screw and barrel due to
deformation of the guide rod during plasticizing and injection. - Universal modular design
A good universal performance allows more than 2 injection groups (barrel and screw
combination) to be optioned by the user for one model of the machine, or the screws
between neighboring models can be interchanged within the same series without any
extra modification, for example series JPH80C-JPH180C, or JPH80H-JPH180H. The user can change the different diameter screw conveniently. - Multi-stage injection speed control can meet various process requirements by adjusting
injection speed to realize automatic changeover of injection speed from low value to the
high one, or vice versa.
CLAMPING UNIT
Full hydraulic, Efficiency, Stabilization and Precision
- The clamping hydraulic circuit is communicated each other to realize a unified and synchronous
action. The maximum clamping force is controlled by the pressure relay. - A great breakthrough in clamping structure of the injection-molding machine. Patented by China, America, Japan and other European countries.
- High precise
The hydraulic circuit of the four big clamping cylinders are interconnected each other in the
fully hydraulic clamping structure. Mold moving and clamping can be operated synchronously
to give a well-distributed stress to the mold. The position is made according to the mold parting face to realize the best stability and
accurate of repeatability. The clamping force can be set by thee computer that receives
the feedback signal directly from a pressure relay fixed at the clamping cylinders.
The data setting will not be affected by any environment temperature. - The feedback from the injection pressure controls the clamping force that is going down
to 30% of the original value when the pressure holding ends, and continuously declines
to zero step by step before opening. The internal stress can be removed effectively and
the opening shock can be avoided to ensure the finish of the product. - High speed
The small hydraulic cylinders drive the mold moving fast and the big clamping hydraulic
cylinders are driven by recycle hydraulic circuit. So this type of machine has the highest
speed than the other same one. - SELF-ADAPTABILITY OF THE MOLD
If there is a proper parallel error at the mold, F1 does not reach a balance condition when
you close the mold just now. F1 (F2) will drive the movable platen moving forward to close
the mold tightly. Self-adaptability can be realized by allowing the structure a proper fluctuation
as backlash compensation.
