Hot runner system consists of the hot mouth, runner plate, of temperature control box,it is a kind of perfect plastic injection molding structure form. The emergence of hot runner technology has been provided a more perfect solutions for difficultiy to filling mold, deformation of large thin wall parts, raw materials waste in runner, multimode cavity mould have different quality of injection molded parts.Nowadays, hot runner mould has been extremely widespread application in each industrial of developed countries and regions.

But every technology has its own disadvantages, hot runner technology is no exception:
1. The mould structure is complex, high cost,aslo high cost of maintenance.
2. The boot process need a period of time, then the technology will be stable, so it is waste more materials.
3. The leaks of the melt, failure of eating element , larger influence on product quality and production progress.

It is very hard and difficult for cleaning the hot runner,because of abovetechnical reasons, Easy purge screw purging compound is a professional chemical cleaning product  for hot runner cleaning, when cleaning of the injection molding machine,thecomplex structure of hot runner can be cleaned at the same time. It is available for customers to save a lot of unnecessary time, and do not damage the screw and the hot runner.
