Blow Molding |

The key component to a consistent and controllable blow-molded part is the quality of the parison produced from shot to shot. This is a challenge since, unlike other plastic processing systems, blow molding is the only process that has the material open to the environment and its influences. Along with the production of poor quality parisons, with thin spots and uneven heating throughout the circumference of the parison, this environmental factor influences part quality and consistency along with all of the other machine and system related variables.
Up to now the industry has not been able to monitor the most important element in the blow molding process, the parison itself. Monitoring this area coupled with understanding the ambient temperature of the interior of the tool is the key to any blow-molders success. Now with Emitted Energy’s Thermal Process Monitoring system utilizing FLIR Infrared (IR) Cameras, blow molders with all types of equipment can monitor parison temperature with precision 100% of the time. This information can be used with SPC/SQC systems to provide excellent quality control. In addition to the predictive capabilities of IR monitoring, we are now able to adjust to the optimum parison temperature for part quality, consistency and part weight. All of this information can be gathered and processed into instant reporting systems and even closed-loop process control. This is only one area where IR technology is used because we can now monitor and QC 100% of all finished blow molded parts for the most minute of changes from specifications. We can monitor surface temperatures for Molds, Head Tooling, Heater Banks and even electrical components, hydraulic pumps and electric motors to even predict potential problems. |
