Hot Runner System is the Preferred Choice in Injection Molding Machines

A hot runner is basically a device that is used in injection molding systems. Injection molding systems are systems that produce various plastic parts using hot runner systems or cold runner systems. A hot runner system combines heated elements to inject molten plastic into the mold cavity of the injection molding machine and this molten plastic is then combined with various other inputs to form plastic parts that are hence used in a variety of industries. The mold cavities are shaped like the parts to be produced, so that when the molten plastic is poured into it, it takes the shape of that mold. When it solidifies and cools down, the part is ready to be used. 

Hot runner systems are more popular than cold runner systems. This is because, the processing time in hot runner systems is lower since there is no need for the machine to first freeze, like in the case of cold runner systems. Also, the costs incurred in running a hot runner system are lower than in running a cold runner system. This is due to a number of reasons, the biggest being that hot runner systems consume less power than their cold counterparts. 

However, these machines are more complicated than cold runner systems since a uniform temperature has to be maintained in the machine very strictly at all times. The slightest mistake in the configuration of the temperature may leas to machine break down, improper parts or poor quality and increased costs.
