Our injection machine can produce a wide range of preform, from 5g to 800g, we have full range injection machine, provide multiple machine model option for customers.

Product Introduction
bottle cap injectiom molding machine
Preform Injection Molding Machine

Guide unit:
With high precision bilinear guide, low friction coefficient, small and uniform injection and plasticizing resistance and faster injection speed, it is suitable for precise injection molding.

Molding unit:
The high strength box formwork based on finite element analysis ensures uniform force, small deformation coefficient, and prolongs the service life of die.
High rigidity T-groove formwork structure, more convenient to replace mold.

Clamping unit:
According to the special optimization design of PET bottle preform forming process, the ejecting force is greater and the ejecting speed is faster than that of the large ejector structure.

Servo motor:
Equipped with high efficiency servo motor and imported high efficiency gear pump system, power saving and water saving can be up to 20% and 50%, and noise is lower.
And the configuration of the motor of the primary or secondary oil pump is increased, the torque is larger, the load is lighter, and the forming period is shortened by more than 20 percent compared with the conventional machine.

Ceramic/Nano heating coil
The ceramic heating ring is used to increase temperature faster, heat preservation performance is good, and 30% electricity is saved, which can avoid bad plasticizing phenomenon due to inaccurate temperature control in the production process of the product.
The injection quantity is increased by 40% compared with that of the conventional machine, and the special brushless motor with large torque PET is provided, the plasticizing efficiency is higher, and the injection period is shorter.
The screw barrel structure specially designed for the PET special machine and the data of the corresponding working elements are seamlessly interfaced to realize the normal operation of lower plasticizing pressure, lower current and higher production capacity.

Advantages
Servo energy saving injection molding machine output power changes with the loading changing. There's no extra waste of power. The motor doesn't work while cooling, electricity consumption is 0. As compared with the tradition injection molding machine, the servo machine can save electricity 20%-80% that brings you excellent profit.
-Excellent energy saving
As compared with the traditional fixed pump injection molding machine, it saves energy 20%-80% under the same working condition.
-Excellent injection molding stability
The pressure and flow of servo drive system applies closed-loop control, as compared with the traditional injection molding machine, it greatly increases repeatability precision of injection molding.
-Fast response
Fast response servo drive, the start time faster than that of the traditional injection molding machine by 50%.
-Environmental friendly
he complete machine runs under low noisy, low speed operation and quite.
-Constant oil temperature
The servo motor output hydraulic oil according to proportion to avoid extra heat. Even the hydraulic oil need not to be cooled to realize excellent water saving.
