DESCRIPTION

HI-SV/P368 PET Preform Injection Molding Machine adopted special prolonged screw, three R/D of screw, 21:1 / 23:1 / 25:1, is available, this machine is used to produce PET performs with weight 5g-800g, neck size 8mm to 150mm.

HI-SV/P368 PET Preform Injection Molding Machine is the type of fully-automatic machine, being provided with high efficiency, high reliability, high speed, low noise, low power consumption and other advantages.

Special designed points for PET(for HI-P series injection molding machine)

Characteristics of PET resin

1. melting point: 250℃-260℃, molding temperature scope of PET is from 255℃-290℃, improved GF-PET can reach 290℃-315℃.

2. Low viscosity degree.

3. Strong moisture absorbing ability.

Our machine’s special design for PET

L/D:21, this is the standard parameter of our PET series injection molding machine.

Enlarged screw diameter and length.

Increased oil pump’s power.

Increased heating ring’s power.

product details

Injection Unit

This unit is composed of plasticizing, material feeding, injection base, pre-plasticizing motor, whole forward-backward cylinder etc., thereinto, injection and mold moving is driven by oil cylinder, and the plasticizing will be realized by screw which is actuated by oil motor directly. Our machine’s injection unit with the advantages as compact structure, reasonable composition, equal plasticizing, high injection press and high speed, very suitable for producing high quality products.

Clamping Unit

Injection unit is composed of mold clamping oil cylinder, mold adjusting device, frontal and rear mold platen, stretch bar, elbow jointed bar frame, moving platen, safety device, central hydraulic ejector etc.

Control Unit

Our standard machine is for 380v/50hz/3phases, the operation power supply is 24v, also we can adjust according to the different power supply standard in different areas.

Hydraulic Unit

This unit is composed of direction valve, proportional pressure valve, proportional direction valve, overfall valve, unilateral valve & pump, and hydraulic motor etc, these components compose the electric-hydraulic proportional loading feedback circuit, which is with fast respond, reliable running, stable action, energy saving, easy to operate, easy to maintain and other characteristics.

Safety Device

Mechanical safety device:

This device is import for protecting operator’s and mold’s safety, if do the mold opening action at a safety door opening condition, the mechanical safety stick will drop down automatically during its backward moving course, so, even if there is any problem on the electric or hydraulic circuit, the safety block will prevent the forward moving of the safety stick if there is the trial mold closing action, accordingly this will prevent the mold closing action to be finished.

Electric safety device:

A. Safe door position-limited switch

The position-limited switch can break off the mold-closing electric circuit, when the safe door open, if you turn on the switch, the electric circuit will be broken off, accordingly the mold-closing action will not be done. If open the safe door during mold closing course, the moving platen will be stopped immediately.

B. Urgent Stop button

Under the urgent condition, you can press the urgent stop button, the oil motor will be stopped, accordingly the machine will be stopped immediately.

COMPETITIVE ADVANTAGE

HI-SV series servo motor system injection molding machine is equipped with high performance servo motor control system, the output power is changing along with load, there is no energy wasting, the power consumption during pressure keeping period is very low, the power consumption during cooling period is zero.

The advantages include high precision injection, big energy saving, low noise.

Compare with HISSON HI-G and HI-P series injection molding machine, according to different products, HI-SV series injection molding machine can save 50%-80% power. Below diagram show the power consumption between HI-SV series and HI-G series standard machine:

Purple curve: HI-G series with Fixed-speed motor-driven dosing pump;

Yellow curve: Based on HI-G series, changed to variable speed motor driven pump;

Green curve: HI-SV series servo motor system machine.

From the diagram, it is obviously to see the energy consumption during mold injection, pressure keeping, material storage, cooling, open and ejection, HI-SV servo motor system machine can save much power.

Heaters adopt ceramic, the using life is double than stainless steel.

Machine with oil filter system to ensure hydraulic oil clean , to prolong action valves using life.

The machine equipped with 7 inch colorful screen controller, brand Techmation from Taiwan, the controller is with several languages include English, French, Spanish, Portuguese, Russian, Arabic etc.
