VALVE GATE SEQUENCING: A NEW OPPORTUNITY FOR PRODUCTIVITY

摘要

As injection molders of the world are constantly squeezed for lower costs and higher quality parts, the use of new techniques and new technology are the keys to accomplishing these goals.An oppor-tunity exists to improve productivity,quality and valve gate technology in conjunction with hot run-ners. In this paper,we will explore other alternatives that actually control each flow front independently in a way that process consistency can approach that of a single cavity,single flow front process.
