Why Design Octaves?

Design Octaves’ 40+ years of RIM Molding mastery mean low cost composite tools that are guaranteed for 10,000 cycles, molded-in metal inserts, and flawless cosmetic finishes.


Design Octaves specializes in molding complex parts (up to 65”) in low volumes from 100 to 5000 parts per year. The RIM Reaction Injection Molding process offers excellent design flexibility and superior cosmetics on high quality, limited run custom enclosures, housings and structural components. Design Octaves builds all of composite aluminum/epoxy tooling in-house and guarantees every tool for a minimum of 10,000 cycles.

Design Octaves’ parts are molded with all details in place with no secondary machining or gluing operations required including molded-in complex undercut features using CNC machined core piece during the molding operation. Design Octaves is one of the few RIM molders who mold threaded inserts in place and provides the advantage of better locational repeatability and much better pull-out strength compared to threaded inserts installed as a second operation.

Design Octaves’ Dow RIM materials can be molded as thin as 0.125” and meet UL 94-V0 or 94-5V flammability requirements. The RIM process offers design freedom, great cosmetics, and tough mechanical properties. Design Octaves’ unique composite tooling process makes molds economical and durable.
