 IntelliMold Closed-Loop Process
Control |
|
| Application Description: Mold-in-color polypropylene liftgate trim panel for a sport utility vehicle. | Single Most Unique Feature: Real time feedback between the internal melt pressure in the mold cavity and the injection molding machine's hydraulic system. |
| Process Descriptions: Injection molding | First Usage of Process?: Yes |
| Formerly Used Process: Replaced standard injection molding with the closed-loop process. | Tooling Innovations: Selective placement of pressure transducers to accurately measure all gas and melt pressure displacement transitions during the injection phase. |
| Material Innovations: NA | Mass Savings: Up to 25% reduction if foamed parts are used |
| Cost Savings: Up to a 20% reduction in cycle time | Cost Avoidance: Scrap savings of approximately 3%, required clamp tonnage reduced by 10% |
| Direct Consumer Benefit: Quality is improved through improved surface finish and a reduction or elimination of sink marks. | Is Technology Transferable?: It can be translated without limitation to other OEM's and other vehicles. |
| Significant Safety Benefit: NA | Significant Environmental Benefit: NA |
