The difference between hot half mold and hot runner

　　Hot Half and Hot Runner are commonly used technologies in plastic injection molding,both of which are related to hot runner systems,but there are some differences in specific applications and functions.The following are the differences between hot half mold and hot runner:

　　1.Definition and Function:

　　-Hot half mold:Hot half mold refers to a part of the mold,usually the feed side(injection side)half of the mold,including the thermal control parts such as the hot runner system,hot nozzle,and nozzle.The hot half mold is used to control and maintain the temperature in the hot runner system,and to melt and inject thermoplastic into the mold cavity.

　　-Hot runner:Hot runner is a system in injection molding that maintains plastic in a molten state through the heating system inside the mold,allowing it to be smoothly injected into the mold cavity.

　　2.Composition and Design:

　　-Hot half mold:Hot half mold refers to a part of a mold,usually including a hot runner system,hot nozzle,nozzle,and other parts,which are usually made of metal or ceramic materials.The design of hot semi molds is usually coordinated with the design of molds to ensure the smooth melting and injection flow of plastics.

　　-Hot runner:A hot runner is a relatively independent and complete system that includes multiple hot runner cores,supporting heating systems,temperature control devices,etc.A hot runner system usually consists of a hot plate,hot runner pipeline,hot runner needle valve,etc.,designed to control the melting,flow,and injection of plastics.

　　3.Application scope:

　　-Hot half mold:Hot half mold is widely used in large and medium-sized injection molds,usually suitable for producing large quantities of complex plastic products.Hot semi molds can achieve uniform temperature control during plastic injection molding,improving product quality and production efficiency.

　　-Hot runner:Hot runner is suitable for injection molds of various sizes and can be used to produce small and medium-sized plastic products.The advantages of a hot runner system lie in reducing plastic waste,improving the stability of the injection process,and changing colors.

　　4.Cost and complexity:

　　-Hot half mold:The cost of hot half mold is usually lower,making it easier to manufacture and maintain.Compared to the hot runner system,the design and manufacturing of the hot half mold is relatively simple,and the required equipment and technical level are relatively low.

　　-Hot runner:The cost of hot runner is usually high,and the design and manufacturing are relatively complex.The hot runner system requires higher technical level and professional knowledge,while maintaining and replacing components also requires more investment.

　　In summary,there are some differences between the hot half mold and the hot runner in terms of function,composition,application scope,cost,and complexity.The choice of technology should be based on specific production needs,product form,and economic considerations.Hot half molds are suitable for producing large quantities and complex plastic products,while hot runners are more suitable for improving product quality and quality.Hot half molds and hot runners are commonly used technologies in plastic injection molding,both of which are related to hot runner systems,but there are some differences in specific applications and functions.The following are the differences between hot half mold and hot runner:
