Reaction Injection Molding (RIM Molding) Design Guidelines

Since thermoforming is a sheet forming process, it cannot produce variable wall thickness without time consuming manual gluing of additional pieces to the thermoformed part. Since the Reaction Injection Molding process uses two liquid components that chemically react to form a plastic material in a mold, wall thickness can be variable. This characteristic provides design, economic, and processing flexibility.

Large parts often require ribbing to stiffen the part and bosses to provide attachment points. The Reaction Injection Molding process provides tremendous design flexibility to meet these needs. For example, wall thickness variation within the same part can vary from .125" to 1.125". In addition, bosses can be incorporated into the mold, which greatly reduces post-processing activities. Where the part is complex, Reaction Injection Molding is the best choice.
