Mold Structure & Design Description

Core and cavity components form the functional geometry of injection molds and directly define the final plastic part shape. Senlan Precision manufactures mold cores and cavities with strict control over concentricity, straightness, and surface integrity. Designs may include straight cores, threaded cores, stepped cavities, or complex profiles depending on molding requirements. All parts are produced to ensure accurate alignment within mold plates and stable performance during repeated injection cycles.
