The selection of heating elements with high resistance is to meet the heating needs of the hot half mold and ensure its stability and efficiency.The following will explain in detail why heating elements with high resistance are selected.

　　1.High temperature demand:The plastic injection molding process usually requires a higher temperature to ensure that the plastic material can flow smoothly and fill the mold cavity.Therefore,the heating element in the hot half mold needs to be able to provide a sufficiently high temperature.Heating elements with high resistance have high electrical power and can reach the required high temperature.

　　2.Fast heating speed:During the injection molding process,the hot half mold needs to reach the set temperature in a short time to ensure the efficiency and productivity of the production cycle.Heating elements with high resistance have a high electrical power,which can generate a large amount of heat and quickly transfer it to the thermal half module,thereby rapidly heating.

　　3.Temperature stability:The hot half mold needs to maintain a stable temperature during the injection molding process to ensure the fluidity and molding quality of the plastic material.Heating elements with high resistance can provide stable heating effects,generate more uniform heat,and are more sensitive to temperature fluctuations.They can respond faster to temperature changes and perform accurate temperature control.

　　4.High temperature resistance:Due to the need for high temperature heating during the injection molding process,the heating element needs to have good high temperature resistance to avoid failure or damage due to excessive temperature.Heating elements with high resistance are usually made of high-temperature materials,which can withstand higher temperatures and ensure the long-term stability of the hot half mold.

　　5.Energy saving effect:Choosing heating elements with high resistance can also improve energy utilization and energy-saving effects.Heating elements with high resistance can provide higher heat output and reduce energy waste under the same power conditions.

　　In summary,heating elements with high resistance can provide high temperature,fast heating speed,temperature stability,high temperature resistance,and energy-saving effects.These characteristics make them ideal choices for hot half molds,meeting the heating requirements for hot half molds during the injection molding process,and ensuring the quality and production efficiency of plastic products.
