Engineering & Mold Design

Successful rubber component manufacturing begins long before the first shot of material enters a mold cavity. CPI offers comprehensive engineering and mold design services that bridge the gap between concept and production-ready tooling. Our engineering team uses advanced CAD software to develop detailed mold designs, performing Design for Manufacturability (DFM) reviews that identify potential tooling issues before any metal is cut.

We design single and multi-cavity molds for compression, transfer, and injection molding processes. Each mold is engineered with precise gate geometry, venting strategy, and parting line placement to ensure consistent fill, minimal flash, and clean part release. Tolerance stack analysis is performed on critical features to guarantee that finished parts meet your assembly and functional requirements.

Collaboration is central to our process. Our engineers work directly with your product design team during the development phase, providing feedback on draft angles, wall thickness, insert geometry, and material flow behavior. This upfront investment in engineering rigor translates directly into reduced tooling iterations, faster first-article approval, and lower total program cost.
