MG-5IIB semi-automatic stretch blow molding machine: stretch blow molder is an ideal equipment to produce many types of PET bottles for mineral water, juice, carbonated drink and edible oil, ect. Also we do have special offer for two stretch blow molders along with one heating oven so that it is compact in size, productive and energy saving. All of those factors make it be the best choice of various plastic bottle productions. 

Overview

Each set of MG-5IIB is composed of two parts: blow unit and preform heater. They control the bottle blowing and preform heating accordingly.
 
*Bottle blow unit 

Simple operation and high control precisionMG bottle blow unit is equipped with specially designed PLC control system. It controls the whole bottle production process through a soft touch pad with time control precision up to 0.01 second.

*High quality pneumatic unit

Pneumatic unit provides power for machine movements including machine driving and bottle blowing. MG-5IIB is equipped with world famous brand components (Festo) to reduce the noise, save energy and produce the high quality production.

*Reliable designed clamping system with perfect performance

MG-5IIB adopts three-plate toggle clamping system to provide powerful clamping force required by high pressure blowing up to 35 bars. Besides, the system has an adjustment device to change the distance between front & middle mold-plate and the position of stretch-seal cylinder required in different mold installation. 

*Plenty of assistant units

MG-5IIB has a plenty of assistant unit to increase the machine’s performance, such as air storage unit to keep the air pressure stable, grease-lubricating unit to reduce mechanical parts’ wear and tear, and multi-utilization air entry unit to meet air compressed air high-pressure single entry mode and high-pressure & low-pressure double entry mode. 

*Reliable safety unit

In order to keep both machine and operator safe, MG-5IIB installs twin startup switches on two sides of the machine, which should be pressed at the same time to start the machine, while there is also an emergency stop button on MG-5IIB to stop machine urgently if necessary. 
 
*Powerful heating capacity with perfect heating result

MG series preform heater adopts infrared lamp as heating unit. Infrared has powerful thermal-radiation capacity, which can heat up preform to required temperature in a very short time, while the strong thermal-penetrability provides continuous and uniform heating inside of preform and over surface of preform. 

*Independent heating control system

MG series preform heater adopts independent temperature control unit for each heating zone to offer ideal temperature for various preform. Each heating lamp has a voltage regulator to control the voltage of the heating lamps and keep it working smoothly. With the LED display, it becomes easy and convenient to inspect and adjust the voltage value.

*Perfect cooling design

MG series preform heater is equipped with air-cooling and water-cooling device to remove the remained heat on preform loader and prevent preform neck from deformation. And reliable air exhaust system placed on the heater keeps heating temperature continuous and stable during preform heating process.

*Multi adjusting device

Multi adjusting device placed on the preform heater increases the machine’s agility. With those devices, the heating channel’s width and height can be changed easily according to the different neck size and neck height. The mouth of the air exhaust system is also adjustable to meet different heating requirement. 

*Assistant unit for easy operation

For easy operation, MG series preform heater is equipped with plenty of assistant units including centralized cooling water supply system, portable base unit for machine’s convenient moving, reliable air entry unit and so on, which makes operation simple and convenient for customer.
 
Operation

* Step 1

place formed preform onto preform holder of reheating unit. The preform holder carries the preform into oval heating channels where preform will be heated under set temperature. After a heat treatment through the heating channel, rotary prefrom holder will carry the heated preform out of heating channel. 

*Step 2

take out the heated preform and place them into the stretch blow mold.

*Step 3 

press two startup buttons at the same tine, the machine starts automatic mold blowing process shown as following.
 
(1) loading preform

(2) pre-blowing with stretching 

(3) shaping with high air pressure  

Step 4
take a finished bottle out of the stretch blow mold. 

Step 5

feed another preform into the rotary preform holder of reheating unit and start another bottle blow process.
