Hot semi mold is a special component in injection molding,which controls the mold temperature through the heating area to improve the fluidity and plasticity of plastic materials.The following will provide a detailed introduction to the advantages of hot semi molds,

　　1.Improve plastic fluidity:

　　Hot semi molds can reduce the viscosity of plastic materials by heating them,thereby improving their fluidity.During the injection molding process,plastic materials need to flow into various cavities of the mold and fill the entire cavity space to form the final product.The heating effect of hot semi molds can improve the fluidity of plastic materials,making it easier to fill the mold cavity,thereby reducing or eliminating defects such as incomplete filling and short shot,and obtaining more complete injection molded parts.

　　2.Improve product quality:

　　By controlling the temperature of the hot half mold,accurate control of the mold temperature distribution can be achieved.This helps to avoid the occurrence of injection defects such as cold lumps and warping.Moreover,hot semi molds can reduce or eliminate temperature gradients within the mold,narrow the temperature differences between the surface and interior of the mold,and thereby improve the surface quality and dimensional accuracy of the product.By reducing or eliminating thermal stress,hot semi molds can also reduce the possibility of product deformation,resulting in more accurate dimensions and shapes.

　　3.Shorten the molding cycle:

　　Compared to traditional cold half molds,hot half molds can accelerate the solidification and cooling process of plastic materials,thereby shortening the molding cycle.By heating the surface and cavity of the mold,the hot half mold can improve the heat transfer rate of the mold,quickly cool and solidify plastic materials.This not only reduces the forming cycle and improves production efficiency,but also increases the service life of the mold and improves production efficiency.

　　4.Improve production stability and consistency:

　　The hot half mold can maintain a stable temperature of the mold through accurate temperature control.A stable temperature can provide more stable injection molding process conditions,ensuring consistency in every injection molding process.This helps to reduce the rate of defective products,improve the consistency of product quality,and bring better controllability and stability to the production process.

　　5.Suitable for special materials and process conditions:

　　Some special plastic materials,such as thermosensitive plastics and high filled glass fiber reinforced plastics,have strict requirements for temperature control.Hot semi molds can meet the requirements of these special materials during the injection molding process through accurate temperature control.In addition,for injection molding processes that require high or low temperature environments,hot semi molds can also provide suitable temperature conditions.

　　6.Saving raw materials and energy:

　　Hot semi molds can improve the flowability and filling performance of plastic materials,reducing or eliminating incomplete stamping.This can reduce the amount of plastic used,reduce waste of raw materials,and thus save costs
