Mold Design & Manufacturing of 46 Cavity Production Mold Assembly for the Automotive Industry
Diamond Tool & Mold has an industry-wide reputation for our ability to design and fabricate molding that streamlines production for specialized applications. We produced the mold assembly pictured here for a customer in the automotive industry. It is designed for use in a rubber-to-metal bonding process for high-volume manufacturing of transmission seals.
Our engineers worked closely with the customer to define both the part and production requirements. They created 2D drawings and 3D models for this 46 cavity mold assembly to simulate and fine-tune its functionality. We specified three grades of steel for the various components, including 4140-PH for the plate assemblies to ensure a high degree of flatness, and 440 stainless for the inserts due to its superior edge retention. Operations consisted of both CNC and EDM machining, heat treating, and finish grinding the components to within extremely precise +0.0005"/-0.0000" dimensional tolerances while maintaining roundness, concentricity, flatness, and parallelism within 0.001" T.I.R. In addition, we polished the cavity area to a 16 RMS finish, leaving no visible scratches or tool marks.
Measuring 35.440" x 32.000" x 7.264", we designed and fabricated this mold assembly with complete geometric precision, guaranteeing the integrity of our customer's component parts.
