Brief introduction

Mega machinery Mold is China professional PET bottle blower manufacturer, supplier and maker. MG-120 automatic PET stretch blow molding machine, PET bottle blower is used to produce five gallon (20L) PET bottle, nowadays 20L sized bottles are demanded extremely in the market. Facing great demand for 5 gallon PET bottle at market, MG-120 will certainly become the right machine for your investment. MG-120 is controlled with microcomputer also could connect with the conveyor, the machine can be connected to the filling machine directly and start inline filling.

Overview

Advanced microcomputer controller controls MG-120 automatic PET stretch blow molding machine, the whole bottle making production from preform conveying to bottle discharge is completed automatically. MG-120 is made up with three main parts: preform loading system, Heating oven & blow station. MG-120 is designed according to CE standard which guarantees the quality of the products, PET bottle blowers.

* Pneumatic system

Pneumatic system provides the power for MG-120's movement. World famous high quality pneumatic components equipped on MG-120 such as Festo from Germany, specially designed high-pressure valve, high precise action, long service life and reliable performance are its highlights. Network of pneumatic components suppliers' global service ensures customers their prompt after-sale service locally for their pneumatic products used on MG-120.

* Sensor system

MG-120 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

MG-120 automatic PET stretch blow molding machine adopts infrared type heating lamps, whose superior thermal-radiation and thermal penetrability provide machine with powerful heating to meet strict preform heating requirement under speedy moving. Number of infrared heating lamps placed onto three heating zone with 9 sets of independent voltage adjusting module and advanced microcomputer controller, can offer ideal heating for preform of different sizes. Each lamp's horizontal position is adjustable to keep the machine agile.

* Clamping system

MG-120 adopts three-plate type toggle clamping unit. Apart from the three-plate type toggle clamping unit, there is a high pressure assistant clamping device that is special designed to get a firm clamping.

* Preform feeding & bottle discharging system

MG-120 automatic PET stretch blow molding machine is equipped with patented prefrom loading system, which protect the neck of the perform from possible damage and allow to make a slight change of preform dimension without changing prefrom holder. The heated preforms are blown with neck up in order to ensure the quality of the finished bottle, and then shaped bottles will automatic discharged during the machine' movement.

Features:

1. Patented Feeding system carries the preform automatically.
2. Suit to produce 5-25L wide mouth PET container
3. Advanced PLC control system with a use-friendly control panel
4. Reliable sensor system monitor machine's auto running
5. Powerful heating unit with precision control and convenient adjusting device
6. Cooling system to get perfect cooling result
7. Compact structure to save space
8. Prevent bottle from possible pollution by worker
9. Equipped with special designed air storage units
10. Simple installation & startup adjustment
