In comparison to a hydraulic injection unit, the servo motor and ball-screw driven injection unit have substantially improved precision of the injection speed, pressure and position repeatability. It thereby ensures the high precision and high stability of the Zhafir JE Series.

The compact design of the two-platen clamping structure has been integrated into the Zhafir JE Series, with optimized space layout and providing larger mold space, extended mold movement stroke and ejector stroke.

Parallel lock nut operation ensures fast and accurate response.

Large moving platen ensures high platen rigidity during movement with increase mold weight loading. Reduced platen vertical movement for long core molds.

With optimized layout and cycle instruction in the SIGMATEK control system, the signal processing speed has improved, which can be seamlessly connected with the peripheral automation equipment. More user-friendly interface, makes it more convenient for the user.

Latest CPU, substantial increase of operational performance

Optimal layout

Automatic equipment for convenient interconnection

Multitude of application software

Interfaces for integration into cyber physical system (CPS)

Matching of the servo motor and servo drive enables further improvement of the acceleration rate and utilization of renewable resources, realizing energy saving.

The new design of the injection unit is more compact: A reduction of single components bring more stability and dynamics in the injection movement. The high speed injection unit 210h reaches maximum injection speed to 500 mm/s. The hydraulic carriage provides high pressure for mold contact with more speed. The nozzle touch pressure and moving speed can be adjusted on the control unit with a two-steps-setting.

The redesigned 5-point-toggle-system increases the platen intensity, reduces platen inertia and joint stress. The optimized mechanical structure provides more efficiency and a quiet machine operation. The design stands for opimized speed curve and reduced dry clycle times.

Sliders for moving platen support heavy mold weight and reduce the coefficient of friction. The platen moves smoother and can be replaced and maintained very easy.

The twin ejector cylinder for the ejector balance can keep ejector back pressure during all cycles. The ejector rapid release coupling allows an ejector bolt connection.

Two integrated hydraulic core puller interfaces are fixed on the moving platen and provide more flow and an increased pressure compared to external power pack solutions. Pressure and flow are adjustable on the control.

The encoder on mold height adjustment decreases the setup times during mold changes.
