(1) Causes of Difficulty in DemoldingExcessive Injection Pressure and Time: If the injection pressure is too high or the injection time is too long, it can lead to excessive filling, resulting in a lo...
When machining parts on CNC machine tools, a processing program is typically created first, which specifies the trajectory and process parameters for the part (such as spindle speed, cutting speed, et...
The acceptance of injection parts consists of internal quality acceptance and external quality acceptance.(1) External Quality Inspection and Acceptance of Plastic PartsUnder normal conditions of inje...
The position of the gate is constrained by the appearance requirements of the molded products. Some surfaces of the product have strict aesthetic standards, which either prohibit the placement of gate...
(1) Reasons for Testing Injection MoldsMold testing is the process of actually injecting plastic into a mold designed and manufactured for plastic products on an appropriate injection molding machine....
The production of hot work dies involves various hot and cold processing steps from raw materials to finished molds. The process performance of die materials directly affects their promotion and appli...
(1) Causes of Cracking:Injection molded products are prone to cracking at the gate, especially near direct gates, primarily because the gate is the narrowest part of the mold flow channel. This requir...
1. The Gating System Design as a Key Issue in Injection Mold DesignThe gating system, which can be categorized into conventional (cold runner) and runnerless systems, is crucial in injection mold desi...
(1) Function of the Gating SystemThe gating system in an injection mold refers to the flow channel for the plastic melt within the mold, extending from the injection machine nozzle to the entrance of ...
Gas assisted injection molding is a special injection molding technology developed on the basis of traditional thermoplastic injection molding technology, which is suitable for special performance req...
