Overview of PET Bottle Blowing machine

Tinyard Enterprise Co.,Limited is one of the top level China overview of pet bottle blowing machine manufacturers and suppliers, welcome to wholesale overview of pet bottle blowing machine from our factory.

Overview of stretch blow molding machine:


Simple operation and high control precisionMG bottle blow unit is equipped with specially designed PLC controlsystem. 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 or SMC) to reduce the noise, save energy and produce the high quality bottles.

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 on surface of the 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 keeps the machine fitting with different prefroms. With those devices, the heating channel's width and height can be changed easily according to the different neck size and neck height.

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.


Produce bottle from 0.1L to 5L(2 cavity) to 6L (1 cavities) 

Output capacity up to 950BPH for 0.1L using two-cavity blow mold. 

Advanced PLC control system with a use-friendly panel and time-control precision up to 0.01second 

Equipped with special designed air storage unit 

Using Infrared preform heater 

Independent Temperature Control for different heating lamp to get ideal preform heating effects 

Heating lamps are adjustable in directions to suit various preforms. 

Simple installation & startup adjustment. 

Waste rate of finished bottle is no more than 0.3%.
