PLATE ACTUATED HOT RUNNER VALVE GATES FOR IMPROVED PART QUALITY AND MOLDING PROCESS CONSISTENCY

摘要

The high growth in the medical market along with the increased demand for high standards in injection molding in the last five years have lead to the emergence of a new class of valve gate hot runner that provides better molding process consistency along with unmatched part quality. This new valve gate hot runner uses a plate to couple valve stems to allow them to be driven by a hydraulic or electrical actuator. The coupling enables synchronicity of stem movement and the drive provides consistent high force. This paper presents this new hot runner technology that found a niche in stringent applications such as small part molding and the medical market.
