Injection mold runner system improvement is an important direction of development of hot runner mold, it and General injection mold is the main difference between pouring system for plastic injection molding process will not be frozen or with plastic parts fall off, so the mold also called runnerless die.
Material saving energy and labour
Injection molding feed system, aggregate, possession of material consumed a large proportion. For these coagulation of secondary use is after crushing squeeze. Chopped mixed fresh after a new molded plastic parts. Existing problems are pollution and plastic parts with a foreign object in forming the second performance. Statistics show that addition of secondary material plastic scrap rate increased by about 5 times and thermoset plastic runner materials become waste products. Can't reuse.
