The 128-cavity honeycomb pin-valve hot runner system is a high-density multi-cavity injection molding solution specifically developed for high-cleanliness, high-precision, and large-quantity thin-walled small parts such as medical syringe needle caps (including insulin needle caps and protective caps). It adopts a honeycomb-style matrix layout and a pin-valve independent material-control design. It is suitable for medical-grade plastics like PP/PE, meets the clean production requirements of ISO 13485 and GMP, and enables synchronous and balanced molding of 128 cavities. It is a core piece of equipment for the large-scale production of medical consumables.
