The hot half mold is an important component of the hot runner system,with the following characteristics:

　　1.Strong thermal control ability:The hot half mold can achieve accurate control of the hot runner in the injection mold through heating elements and temperature control system.According to the requirements of the injection molding process,the temperature of the hot half mold can be adjusted to ensure the melting and fluidity of the plastic,and to control the dimensional accuracy of the injection molded parts.

　　2.Improve the quality of injection molded parts:The hot half mold can evenly distribute temperature,eliminate stress and defects generated during the cooling process of injection molded parts,and improve the surface quality and dimensional stability of injection molded parts.It can effectively reduce the occurrence of adverse phenomena such as warping,shrinkage,and short shot.

　　3.High manufacturing efficiency:The hot half mold has the ability to quickly heat and cool,which can shorten the injection molding cycle and improve production efficiency.By optimizing the design and temperature control of the hot half mold,faster plastic melting and solidification processes can be achieved,shortening the injection molding cycle.

　　4.Energy and material conservation:Hot semi molds can reduce the cooling time of plastics and the loss of melting energy,thereby reducing energy consumption.Meanwhile,due to better thermal control,the waste rate of plastics can be reduced and material waste can be reduced.

　　5.Improve working life:The temperature distribution of the hot half mold is uniform,which can reduce thermal stress and fatigue,and extend the service life of the mold.Especially for the processing of high heat resistant plastics,the deformation and damage of the mold can be avoided through hot semi molds.

　　It should be noted that the design and use of hot semi molds also need to consider factors such as the characteristics of plastic materials,product shape,and process requirements.Different injection molding processes may require different hot half mold designs and temperature control strategies.Therefore,when using hot half molds,it is necessary to debug and optimize according to the specific situation to achieve the best processing effect and economic benefits.
