MG-90 stretch blow molding machine
Brief introduction
Mega machinery Mold is China professional semi-automatic stretch blow molding machine manufacturer, supplier and maker. MG-90 PET stretch blow molding machine, blow moulder is specially designed to produce 5-gallon bottle 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 in certain case.
MG-90 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. |
Overview
MG-90 stretch blow molding machine consists of two parts: bottle blow unit and preform heater.
|
|
*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-90 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. blow moulder, blow molder
|
*Plenty of assistant units
MG-90 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 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. blow moulder, blow molder |
|
*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 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 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. blow moulder, blow molder
|
*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. |
|
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. |
Features:
1. Special design for PET Gallon Bottle up to 6 Gallon
2. Produce wide mouth jar up to 25 liter with neck size up to 200mm.
3. Using Infrared reheat units to achieve uniform heating throughout the wall of preform
4. Adopt special designed preform heating system to ensure the optimal heating effect for 730g thick-wall preform
5. Special designed fan-cooling system in the heating channels to keep the oven with constant temperature and ensure the preform can be heated completely.
6. Water cooling system ensures the quality of preform neck.
7. Up to 90 bottles/hour using one-cavity mold for 5-gallon bottle
8. Use advanced PLC control system with counting function and time-control precision to 0.01second, and a use-friendly panel.
9. Equipped with special designed air storage units
10.Simple installation & startup adjustment |
