PET Preform Making Machine / PET Preform Plastic Injection Moulding Machine
Injection Molding Machine
Plastic Machine Injection Adopting Europe technology, hydraulic unit adopts proportional pressure and flow control, the pressure and the speed can be adjusted, stable movement curve and gentle shock, the computer is imported from Industry family. The LCD displaying screen with high clarity has Chinese and English language to use. Close-loop PID temperature control with the advantage of high precision. The operating table of the injection moulding machine have two safety, one is machine safety, another is electrical safety, that ensures the operators's safety.
MOLD CLAMPING PART
The inverted double-toggle three-rod five-hinge mold clamping structure with the optimized design features as the balanced movement, large mold moving stroke, fine rigidity. Four-step mold clamping pressure, speed, differential quick clamping device has the multiple ejection modes and functions.
-Horizontal double-toggle five-hinge hold-in design. It utilizes its own structural features to increase the opening stroke and rod pitch etc. Meanwhile it avoids hurting the mold (small machine) because of inclined mold board due to uneven force caused by dead weight of vertical parts.
-Up/ down double-toggle five-hinge hold-in design (medium and big machines)
-High rigidity, high intensity box style integrated mold board analyzed by finite element reduces the accumulated error caused by the multiple processing and assembly. It thus increases the mold clamping accuracy.
-It applies quantitative automatic lubricating system. It regularly or sequently executes quantitative oil supply to various lubricating points. It is effective and economical.
-Low-pressure mold protection function prevents from mold damage.
-Mold clamping structure has mechanical, electrical and hydraulic triple safety devices. It is used to ensure the staff security.
-It is of high automatic mold adjusting precision. In renewing the mold, it can fulfill self-adjustment of mold clamping force through setting the parameters.
-Quick mold clamping system applies oil-pressure differential circuit. It increases mold clamping speed, reduces the forming cycle.
-High intensity rod plated with hard chrome matches with automatically lubricated copper wire. It is of smooth movement and long life.
Ejector pin applies position transducer control. It brings about the accurate forward and backward positioning
