MG-S4500 automatic stretch blow molding machine
MG-S4500 automatic stretch blow molding machine with 4 cavities

Brief introduction

Mega machinery Mold is China professional rotary PET stretch blow molding machine manufacturer, supplier and maker. MG-S4500 is the fastest liner blow molding machine in mainland of China by now. Thanks to our president and our research team’s efforts, MG-S4500 reaches around 4500BPH for 350ML bottle. Its baking tunnel is separated from the blow station so that time for mold opening is shortened with a result of speedy blowing and high output, damage to machine is lessened so as to keep reliable performance and prolong service life, as well as machine runs more smoothly and steadily.


* Brief introduction
Controlled by PLC, the whole process of MG-S4500 from preform feeding to bottle discharging is completed automatically, with advantages of labor saving and no pollution. MG-S4500 consists of three main parts: preform loading system, Heater channel & blow station. MG-S3000 is designed by European CE symbol measured up to ISO9001 standard, guaranteeing the quality of the products.

* Control system
Together with HITECH Man-Machine Interaction (MMI) control panel with user-friendly touch screen, the whole control system presents super performance with precise control, convenient parameter setup, obvious display and reasonable memory.
* Pneumatic system
Pneumatic system provides the power for MG-S4500’s movement. It is equipped with world famous pneumatic components such as Festo from Germany. High precise action, long service life and reliable performance are their highlights. With global service network, those pneumatic components suppliers provide customer their prompt after-sale service locally for their pneumatic products used on MG-S4500. pet stretch blow moulding machines
* Sensor system
MG-S4500 adopts high quality imported sensor & switch system including proximity switch, photoelectric switch, and electronic magnet switch to keep production process going step by step and avoid any possible damage on machine.

* Heating system
The machine employs the infrared lamp with the ceramic reflector layer, the layer can reflect the infrared that shoot on the poor light side of the lamp effectively so that the heat energy can be utilized completely, at the same time reduce temperature of the reflection board on the equipment evidently and prolong the life of the equipment. Speedy temperature rise, higher heat efficiency and convenient temperature control.

* Clamping system
MG-S3000 adopts four-plate type toggle clamping unit to provide powerful clamping force and increase the speed of mold opening and closing. Apart from the four-plate type toggle clamping unit, there is a high pressure assistant clamping device that is special designed to get a firm clamp.
* Preform feeding & bottle discharging system
MG-S4500 automatic stretch blow molding machine is equipped with patented prefrom loading system, which consists of two manipulators: rectilineal manipulator and overturning manipulator. The rectilineal manipulator moves preform with neck up to the preform holder, after heating, the overturning manipulator grips heated preform and overturn 180°, put preform to blow station with neck down. After stretching and blowing, the bottle is taken off by overturning manipulator with neck up. The specially designed preform loading & bottle discharging system avoid possible damage to preform & bottle during transportation.

1. Separated baking tunnel and the blow unit provide speedy blowing and high output.
2. Compact design saves space, lower investment and enhances competition.
3. Feeding system carries the preform automatically.
4. Advanced PLC control system with a use-friendly control panel.
5. Independent & simple linear running system.
6. Powerful heating unit with precision control and convenient adjusting device.
7. Equipped with special designed air storage unit.
8. Cooling system to get perfect cooling result.
9. Every movement is driven by cylinder instead of oil pump, no pollution.
10. Waste rate of finished bottle is less than 0.3%.

The standard operation of MG-S4500 linear stretch blow molding machine includes four steps as follow:
Step 1. Put the preform into preform container and the moving manipulator will take the preform to orientation units automatically.
Step 2. Load the preform with neck up to preform holder, and then preform is conveyed into baking tunnel.
Step 3. After heating, preform is loaded into the blow station by overturning manipulator with preform's neck down, then close the mold, stretch and blow under low pressure and high pressure, exhaust, open the mold.
Step 4. The finished bottle is taken off by overturning manipulator.
