Hot runner mold, hot runner system, also known as hot runner system, mainly by the hot sprue sets, hot runner board, temperature control box composition. Our common hot runner system has two types of single-point hot gates and multi-point hot gates. The single-point hot gates are used to inject molten plastic into the cavity directly with a single hot-gourd sleeve. It is suitable for plastic molds with single-chamber single gates. Multi-point hot gates are used to distribute the molten material through the hot runner. And then into the cavity, it is suitable for single-chamber multi-point feed or multi-cavity mold. Such a mold structure and the water outlet is roughly the same, its considerable difference is the flow channel in one or more with constant temperature The hot runner plate and hot spoons mouth, no cold material stripping, runner and gate directly on the product, so the flow channel does not need stripping, this system is also known as the water nozzle system, can save raw materials for raw materials More expensive, products require a higher situation, the design and processing difficulties, the higher the cost of the mold.
Diversion die: the flow channel and the gate in the parting line, and the product in the mold when the mold release, the design is quite simple, easy processing, low cost, so more people use the water system operation.
Water nozzle mold: the flow channel and the gate is not parting line, generally directly on the product, so to design a group of water nozzle sub-line, the design is more complex, more difficult processing, generally depending on product requirements and selection of fine water system The
