Introduction: There are 4 choices of Can Mold Injection Blow Molding Machinery

1. Inverted Head


This is the most popular range of Injection blow molding machine because all hydraulics are situated beneath the mold in the base of the machine. The system is fool proof and does not allow oil from the hydraulics to contaminate the mold or the finished product. The machine has the added advantage of using a pull down tiebar system which is excellent for large cavitations used in the 135 Ton and 189 Ton range. The alternative is hydraulics above the mold where leaking may occur, thus contaminating the mold area. Furthermore, applying pressure more to the center of the mold than the pull down outside tiebars often inhibits the complete formation of the outer molds because of flexing. Large machines of the non-inverted head type, also are susceptible to frame cracking because of the flexing. A full range of machines is available >From 57 Ton to 189 Ton.

2. Inverted Head Hybrid


The same range of machines is available in hybrid electric, with the screw being full electric and the main motor being servo assisted.

3. Inverted Head Full Electric


The same range of machines is also available in full electric.

4. Non inverted head machines (Can Mold NEXION Series)


These machines are generally lower cost and are available in a range up to 3 models 38 Ton, 60 Ton and 75 Ton. Hydraulics are above the head and the machines include an electronic gear box for accurate rotation.
