The 16-cavity bottom cover mold, optimized for large-scale mass production, achieves dual improvements in capacity and efficiency through process upgrades. The compact mechanical layout with 16 cavities has evenly and reasonably arranged cavities, ensuring balanced mold stress during Injection Molding, avoiding unbalanced load deformation, and guaranteeing continuous and stable operation of equipment. The gating system adopts Hot Runner + needle valve gate design, optimizing the melt flow path, enabling plastic melt to be quickly and accurately distributed to each cavity. The 16 cavities are filled synchronously, with a short molding cycle, and the dimensional error of the bottom cover is strictly controlled within 0.05mm. The split core-cavity structure simplifies the maintenance process, allowing separate replacement of wear parts, improving maintenance efficiency, greatly shortening downtime, and reducing maintenance costs by more than 60%. The hard film coating on the cavity surface enhances wear resistance, extending the service life to 1.2 million cycles, enabling long-term high-intensity continuous production, and providing strong support for enterprises to improve mass production efficiency and reduce comprehensive costs.

Design Features: Adopts a compact mechanical layout of sixteen cavities in one mold, with uniform cavity arrangement. The gating system is equipped with a hot runner + needle valve gate design to achieve precise distribution of plastic melt. The core and cavity adopt an inlaid structure, and the cavity surface is treated with a hard film coating. 

Core Parameters: The force on the mold is balanced during injection molding, the filling speed of each cavity is consistent, and the dimensional error of the 16 formed bottom covers is controlled within 0.05mm. The wear resistance of the cavity is increased by 3 times, and the service life is extended to 1.2 million cycles. 

Advantages: It can effectively avoid mold deformation caused by eccentric loading. Vulnerable parts can be replaced separately, reducing maintenance costs by more than 60%, and realizing efficient and low-cost production of bottom covers.
