Advantages of Hot Runner systems for plastic molds
1) no outlet material after processing is not required, so that the entire molding process is fully automated, saving time and increasing efficiency.
2) the pressure loss is small. Hot runner temperature and the injection molding machine nozzle temperature equal to the raw surface to avoid condensation inside runner, injection pressure loss.
3) outlet material will be reused plastic performance degradation, and use the hot runner system has no outlet material can reduce the loss of raw materials, thereby reducing production costs. Temperature and pressure in the cavity uniform, small plastic parts stress, uniform density, in the smaller injection pressure, a relatively short molding time, better than the average of the injection system of the injection molding product. For transparent parts, thin pieces, large plastic parts or high demand plastic parts can show its advantages, but also can be used to produce a larger product smaller models.
4) thermal spray nozzle using standardized series design, with a variety to choose from a nozzle head, good interchangeability. The unique design of the processing of electric heating coil, heating temperature uniformity can be achieved, and long service life. Hot runner system is equipped with manifold plate, temperature control, etc., compact design, a wide variety, easy to use, stable and reliable quality.
Do you need hot runner mold for your business or your new products? Here I offer you some finally suggestion, if you want your plastic mold to running for over 1 million shot, then we suggest you to make hot runner mold, because this will save your cycle time and save the runner waste, if the mold life requirement less than 0.2 million then we suggestion use could runner, of course this is not always the same it is depending on the part size if part size is over 300 mm, then hot runner will be better option, you can go to our mean website to know more about this.
