MG-HR-2500 automatic stretch blow molding machine
Overview

* Brief introduction

Advanced PLC controls MG-HR2500 automatic bottle stretch blow molding machine, the whole bottle production from preform conveying to bottle discharging is completed automatically. MG-HR2500 is made up with three main parts: preform loading system, Heater channel & blow station. MG-HR2500 is designed by European CE symbol as well as MG-HR2500 is measured up to ISO9001 standard, which guarantees the quality of the products.

* Blow unit

It adopts multiple blowing to reduce the residual stress and ensures only slight shrinkage during hot filling. In addition, MG-HR2500 adopts the neck up blowing mode and ensures quality of the heated preform and the reliable performance of the finished bottle.
* Control system

The control system is the heart of MG-HR2500 automatic blow molding machine. Together with HITECH Man-Machine Interaction (MMI) control panel with user-friendly, 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-HR2500's movement. World famous high quality pneumatic components are equipped on MG-HR2500 such as Festo from Germany. High precise action, long service life and reliable performance are their highlights. Those pneumatic components suppliers' global service network provide customer their prompt after-sale service locally for their pneumatic products used on MG-HR2500.
* Sensor system

MG-HR2500 adopts high quality imported sensor & switch system including proximity switch, photoelectric switch, electronic magnet switch to keep production process going step by step and avoid any possible damage on machine.
* Heating system

MG-HR2500 automatic stretch blow molding machine adopts infrared type heating mode, whose superior thermal-radiation and thermal penetrability provide machine with powerful heating to meet strict preform heating requirement under speedy moving. Infrared heating lamp placed onto three heating zone with independent voltage adjusting module and advanced microcomputer controller, can offer ideal heating for preform of different size. Each lamp's horizontal position is adjustable to keep the machine agile.
* Clamping system
MG-HR2500 adopts three-plate type toggle clamping unit to provide powerful clamping force. 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-HR2500 automatic stretch blow molding machine is equipped with automatic prefrom loading system, which protect the neck of the perform from possible damages and allow the dimension of the prefrom to make a slight change without changing prefrom holder. The heated preforms are blown with neck up so as to ensure the quality of the finished bottle, and then shaped bottles will automatic fall down during the machine' movement.

*Operation

The standard MG-HR2500 operation contains four steps following:

Step 1. Put the preform into preform container and the conveyer 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 conveyed into the blow station, 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 automatic discharging system
