SMS-J Blow System
Special for Wide-mouth Jar
Overview

Our customer benefit from KRONCE-SMARGON’s PET process experience and from the construction and design of stretch blow molding machines that meet the requirement for the cost-effective, reliable and precise production of high-tech PET bottles with top output and machine availability. We call this “Value Added Bottle Blowing” – a high demand which is met by the key features of our SMS-J series machine.

SMS-J series is a kind of two-stage type PET Semi-auto Stretch-Blow Molding Machine to produce wide mouth PET Jar from preforms. Its preform holder, which is used to support the preform, has been placed on the chain-wheel unit, and only one worker is required to put perform onto machines preform holder. Then, controlled by SIEMENS PLC system, the preforms on the holder will pass machines heating area driven by chain-wheel unit for heating, being blown into bottle and discharged from the machine in turn and automatically.

Technical Description

1、Preform Feeding

The preforms are feeding by hand, simple and no skill required.

2、Heating Conditioning

Preform enter the oven, neck down, protected against overheating via water-cooling circle.

3、Stretch-Bowing

After heating, the preforms are introduced into the blowing mold. The high-pressure blowing is activated after the pre-blowing, with adjustable times

4、Bottle Ejection

Once the bottles have been blown, they are transferred outside the blowing mold by means of a simple mechanical system.
