MG-90 PET blow moulding machine for Large PET bottles

Brief Introduction

MG-90 PET blow moulding machine for large PET bottles is specially designed to produce 5-gallon PET container and 25L wide mouth jar. Its max output is up to 90 BPH for 5-gallon bottle and even could reach 120 bottles per hour for the one way used thin wall 5 gallon bottles.
MG-90 PET blow moulding machine consists of main unit and rotary infrared heater. The ordinary quartz lamp cannot heat preform ideally because the preform wall is excessively thick. The infrared heater with high penetrative force can heat the inside and outside of preform simultaneously and keep preform in even heating, therefore high shaping quality.

OverviewMG-90 PET blow moulding machine consists of two parts: bottle blow unit and preform heater.

* Blow unit
Simple operation and high control precision
MG 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-90 PET blow moulding machine is equipped with world famous brand components (Festo, SMC) to reduce the noise, save energy and produce the high quality bottles.

* Reliable designed clamping system with perfect performance
MG-90 adopts three-plate toggle clamping system to provide powerful clamping force required by high pressure blowing up to 35 bars. And 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-90 PET stretch blow moulding machine has a plenty of assistant units 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-90 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-90 to stop machine urgently if necessary.

* Powerful heating capacity
MG-90 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 preforms. Each heating lamp has a voltage regulator to control the voltage of each 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-90 PET blow moulding machine’s 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 performance. 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 unit 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.
