10 Considerations for Good Quality Extrusion Design - Condale
Generally the same rules apply as rigid plastic profile design except that the process of extruding flexible plastic profiles allows for variable wall thicknesses. 9. Dual density co-extrusion To achieve a dual hardness co-extrusion with both rigid and flexible properties, two machines are used to feed the separate materials through the same
Best Practices in Extrusion Design | Extrudex, LLP
To achieve the best practices in extrusion design, one of the first things to think about is the wall thickness of your product. Having an even wall thickness makes the high level of quality that you want achievable.
Tips and Techniques: Boosting Extrusion - Plastics Technology
In many extrusion operations the plastic is dried before processing to remove moisture. This is particularly important in plastics that undergo hydrolysis, like PET. If the plastic is dried at elevated temperature, the plastic should be fed to the extruder at elevated temperature.
GPI, Sierra Plastics, & GPM PLASTIC EXTRUSION DESIGN GUIDE
Plastic profile extrusion is a molding method in which plastic resin is continuously melted, pushed through a die with the desired cross-section (a “profile”), and then pulled through a water bath until fully cooled. The formed plastic can then be fabricated and either cut into multiple parts or wound as a single part.
