Abstract
The transition from single-cavity prototype molds to multi-cavity production tools offers significant advantages in high-volume plastic injection molding. This paper examines a case study where a multi-cavity tool was implemented to address production inefficiencies for tube and cover assembly’s tools. By leveraging advanced manufacturing techniques and collaborative design efforts, production speed increased fourfold, reducing operational costs and ensuring readiness for projected annual volumes of over half a million units by 2026. The results demonstrate the cost-justification of multi-cavity tooling, eliminating the need for post-molding annealing for tube parts and achieving optimal efficiency for cover parts as well.
