Is Your IBM Process Leaving Output on the Table?
When an injection blow molding process starts to drift, cycle times increase, or bottle quality becomes inconsistent, it’s tempting to start changing process parameters. Before you do, check the basics.
Verify water temperature and flow, air pressure, material condition, heater temperatures, mold cooling, and machine settings. Make sure the mold and core rods are properly set up and that mechanical components are functioning as intended. A surprisingly large number of processing problems can be traced back to one of these fundamentals.
Next, look at what the process is telling you. Are all cavities filling evenly? A short-shot test can quickly reveal whether material is being distributed consistently across the mold. Compare bottle weights and wall distribution cavity-to-cavity, and look for differences in cooling or preform temperature. Don’t overlook cycle time, either. Small delays in injection, cooling, mold movement, or part removal can add up to significant lost production over thousands of cycles.
If you’ve checked the basics and still aren’t getting the performance you expect, Jomar can help. We know the interaction between the machine, tooling and process because injection blow molding is all we do. Whether the issue is cycle time, mold balance, bottle quality, machine setup or operator training, our service and process teams can help identify where improvements can be made.
Sometimes getting more from your IBM operation doesn’t require new equipment—it starts with getting the most from the equipment you already have.
