Injection Molded” Jason Zhu, PolyOne: “Comparison of Flame Retardancy Performance: Injection Molding vs. 3D Printing” Caption: This prototype heat sink for an LED ceiling light was molded in PVC from 3D printed inserts produced at the PolyOne Innovation Center in Avon Lake, Ohio.

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.

What’s more, the polymer enabled HellermannTyton to switch from a two-step metal fabrication process to a one-step injection molding process, while Avient provided additional assistance with tool development, process optimization and testing. Injection molding = cost savings: Compared with metal fabrication and its time-consuming secondary operations, injection-molded plastics are produced as a net-shape part in a single step, which boosts productivity and lowers system costs.

Most fluoropolymers, other than PTFE and polyvinyl fluoride (PVF), can be melt processed using conventional thermoplastic extrusion or molding techniques. PTFE can be applied as a coating, extruded as a paste, or molded using compression molding or metal powder-processing techniques.
