The 32-cavity pin-valve hot runner system is a multi-cavity hot runner solution specifically developed for small-sized and high-volume injection-molded parts such as medical syringe needle caps, small precision plastic consumables, and miniature electronic components. It adopts a balanced runner layout and an independent pin-valve glue-sealing structure. It is suitable for commonly used medical-grade raw materials such as PP, PE, and ABS. With stable molding, aesthetically pleasing gates, and no drooling or stringing, it balances precision, efficiency, and cost-effectiveness. It is the mainstream preferred configuration for the mass production of small-to-medium batch precision medical consumables and small plastic parts.
