SPI Guidelines for Injection Mold Surface Finish

SPI guidelines provide injection molders and product designers with a standard way to describe the surface finish of molded plastic parts. These guidelines were defined by the Society of the Plastics Industry (SPI), a U.S.-based trade association that’s now known as the Plastics Industry Association (PIA, or PLASTICS). By providing a “common language” for surface […]

Thermoplastics vs. Thermoset Plastics: Material Properties Overview

Thermoplastics and thermoset plastics are classes of polymers used in injection molding, CNC machining, 3D printing, and urethane casting. Like elastomers, another class of polymer, thermoplastics and thermosets both consist of long, repeating chains of molecules. Under a microscope, the structure of a thermoplastic resembles a railroad track while a thermoset material looks like a […]

Product Study: Gate Sizes and Placement in Injection Molding

The Challenge: Avoid Gate-Related Part Defects Injection molding gates are larger or smaller in order to support the direction and volume of flow into the mold cavity. If a gate is too large, molten plastic may fill the cavity unevenly and cause part defects such as weld lines and shrinkage. If a gate is too […]
