Continuous extrusion
Multi-layer coextrusion, with one to seven layers of plastic in the finished part
In some applications, In Mold Labeling (IML) can be integrated with little or no cycle time penalty
Parison programming capability, for optimization of wall thickness
Reduced cycle time on light weight containers, compared to shuttle machinery. Conversely, wheel equipment may suffer cycle time penalties on thick containers
Easily implemented view stripe capability
Ability to achieve very high outputs from a single machine - lowest "cost per bottle" when compared to other blow molding equipment
Higher production efficiencies than most other extrusion blow molding equipment types
Disadvantages:
Inability to produce bottles with calibrated neck finishes
Downstream trimming required
Machines typically dedicated to a narrow range of sizes. Product change can be difficult, especially when downstream trimming changeovers are required.
High initial capital investment
