As a high-capacity mold for large-scale production, the 16-cavity bottom cover mold features high-precision molding and consistent quality as its core advantages. The optimized compact mechanical layout with 16 cavities has evenly arranged cavities, ensuring balanced mold stress during Injection Molding, structurally eliminating deformation caused by unbalanced loads, and guaranteeing stable precision of each batch of products. The combined gating system of Hot Runner and needle valve gate can precisely control the distribution amount and filling rhythm of plastic melt, realizing complete synchronization of the filling process of 16 cavities. The dimensional error of the molded bottom covers is ≤0.05mm, with smooth and flat surfaces and no obvious defects. The core and cavity adopt a split structure, with wear parts designed specifically for easy and efficient separate replacement, greatly reducing maintenance costs and downtime. The hard film coating on the cavity surface enhances wear resistance, with a service life of up to 1.2 million cycles, achieving the mass production goal of high precision, high efficiency and low cost.

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.
