(1) the big water outlet mold: the runner and gate are on the parting line and demoulding with the product when opening the mould, the design is the most simple, easy to process and the cost is low, so many people use the big water system operation.


(2) fine nozzle mold: runner and gate are not on parting line, usually directly on the product, so we need to design more than one group of water outlet parting line. The design is more complex and difficult to process. Generally, we need to select the fine nozzle system according to the product requirements.


(3): this kind of hot runner mold mold structure and fine nozzle is roughly the same, the biggest difference is the flow in one or more of the constant temperature hot runner plate and heat pump mouth, no cold material stripping, runner and gate directly on the product, so the channel need not release, this system also called nozzle the system, which can save raw materials, suitable for raw materials more expensive, higher requirements of products, design and processing difficulty, high cost of mold.
