These unidirectional fiber-reinforced strands are then cut into 1/2 inch (12 mm) composite pellets for convenient processing into net shapes via injection molding. Long glass fiber is a strong yet ductile fiber reinforcement solution that is commonly used in metal replacement applications due to the high strength properties, lower specific gravity and attractiveness of the injection molding processing method. In conjunction with the advantages of organic design possibilities from the injection molding forming process, it is common to see a 40-50% weight reduction in applications when switching from metal incumbents (aluminum, magnesium).

Viscosity changes also influence other process parameters, such as hold time in the mold and temperature profiles, impacting the total cycle time of the process Ensure that cooling in the molds is operating efficiently and is balanced, and plan on revising the injection and temperature profiles Maintaining brand color equity, part dimensions, and mechanical properties are areas of concern when PCR is included at 30% or more in the molded part.

This predictive simulation technology factors in conventional (isotropic) and advanced (anisotropic) modeling data from material characterizations, mold filling analysis, and finite element analysis (FEA). Based on static and dynamic data, the virtual simulations can more accurately predict where an injection molded plastic part may crack or break when exposed to physical loading forces or a sudden impact (crash simulation). To exemplify the improved accuracy of FEA capabilities, Avient tested and analyzed the performance of an injection-molded automotive connector rod, a traditional metal component, using isotropic and anisotropic material mapping.
