The hot runner system is in thermal equilibrium, the ideal state of the system make sure the security of given heating. Hot runner heater can be uniformly heated, and compensate for lost heat. By sensitive thermocouples and temperature controller, effective and accurate temperature control of the manifold of the program and nozzles. hot runner heaters in order to be carried out in the hot runner structure reasonable and along with a reasonable temperature measurement points in each heating zone. The heater should be reliable insulation and safe, durable, the converter should have strong to prevent mechanical damage and anti-corrosion ability. The configuration of the manifold heater and also the heating zone is divided, the first consideration, and your own selection and arrangement of the structural design of the heater. Flow channel plate is split into a plurality of heating zones, the implementation of the independent temperature associated with each heating zone feed corresponds the single or a plurality of nozzles, the manifold is divided into several heating zones, depending near the number and measurements of the nozzle. Each point of injection nozzles has a hot runner heater, thermocouple including heating zone. Apart from a few shorter mainstreams Road unheated and independent heated sprue nozzle is another heat zone. Nevertheless the effect precise adjustment of the temperature of the board of the flow channel of the multi-cavity mold, the fewer the number of zones, the lower the cost belonging to the equipment. Each zone shows a thermocouple and an independent heater. The connectors are properly connected with the temperature as well as the heating element grouping, otherwise it will burn components. The common manifold using the external method heat source in the board of the melt flow channel of the outer wall in the flow channel. The hot runner within the internal manifold and the nozzle inner heating to improve the temperature distribution each morning gate area. However the high technical difficulties within the heated flow channel plate to save energy and low-cost, in order to understand operate, but it is rarely applied. Plate within the heating is the heating rod as a mandrel is placed in the center of this flow channel. Click here to enjoy a deep knowledge about hot runner and hot runner mister nozzles.
