Abstract
For plastic injection process, not runner system was applied in the order of cycle time and plastic feeding system deduction. In this research, hot runner system and beryllium copper (BeCu) mold insert ware used for injection process efficiency increasing. Plastic part in this study was spray cap which had thin shape and high quantity requirement. From the results, hot runner system decreased plastic material from feeding system approximately 17%. In case of BeCu insert, cooling time reduced approximately 46% when compared with convention insert material. Injection cycle time reduced 35% when compared with previous process.
