Thought of thought, thought of thought - - thought of thought [] Southern China organizers Injection Technology Management Consultants Limited (authoritative, professional, brand) [media] support Chinese injection talent network, training network, Southern China China injection molding technology advisory network, China net, plastic injection mold Chinese Talent Network [training] object injection related enterprises Deputy General Manager / Supervisor, injection molding, injection molding engineer, Test Engineer / Technician, injection Department foreman / Team Leader / Technician, engineer, injection quality engineers and other related technical management personnel...... Thought of thought, thought of thought - - thought of thought The - - - - - - - back - Jing Cheng class The injection molding shape is very complex, customer requirements for product quality is more and more high. Due to the geometry of various parts of injection molding products and gate runner system, different control procedures, multi-stage injection molding in the injection molding process parameters it has different injection speeds and different injection pressure in different positions, in order to prevent and improve the appearance of plastic injection adverse phenomenon, improve the quality of plastic parts. Modern injection molding machine has multiple injection control functions (such as multilevel, multi-stage back pressure, melt multi-stage injection pressure, multi injection speed and multistage pressure etc.), however, in the actual setting of injection molding process, injection molding a lot of workers not the proper use of multi-stage injection molding control program, especially not to look for the position of multi-stage injection molding.
