Improving Design of Cricoid Plastic Gating System Based on Moldflow

摘要

To solve the problems such as poor ventilation and high production costs in the production of cricoid plastics, we analysis the reasons and look for solutions with Moldflow software to guide the new design and manufacturing of the mould. The poor ventilated structure is changed into a ventilation structure. A poor ventilation structure is changed to a good ventilation structure. Injection weight ratio was reduced from 35% to 15% - 20%, the gating system was improved, the molding process was optimized, ensuring product quality and save the cost, produced good economic benefits. The cost of injection molding determines the injection molding companies' production efficiency, thereby affecting the injection molding companies' core competitiveness and competitive advantage [1]. In this paper, according to the too large partition accounted by the Cricoid plastic gating system in injection weight, improving the gating system design of the Cricoid plastic parts as the main research content, through the collaboration optimized design of structure and process, achieve the good economic returns while ensuring the product quality.
