Product Description
Moulds can be divided into three types according to the different pouring system:
(1) Large nozzle mold: the runner and gate are on the parting mold line, and the product is demoulded when opening the mold, the design is the simplest, easy to process, and the cost is low, so more people use the large nozzle system operation.
(2) fine nozzle mold: the runner and gate are not on the parting line, generally directly on the product, so it is necessary to design more than a group of water parting line, the design is more complex, the processing is more difficult, generally depending on the product requirements and choose the fine nozzle system.
(3) Hot runner mold: This kind of mold structure is roughly the same as the fine water mouth, the biggest difference is that the runner is in one or more hot runner plates with constant temperature and hot mouth, no cold material demoulding, the runner and gate are directly on the product, so the runner does not need to demoulding, this system is also known as no water mouth system, can save raw materials, suitable for more expensive raw materials, products with higher requirements, design and processing difficulties, The mold cost is higher.
Hot runner system, also known as hot runner system, is mainly composed of hot gate cover, hot runner plate, temperature control box. Our common hot runner system has two forms of single point hot gate and multi-point hot gate. A single point hot gate is a single hot gate sleeve that directly pours molten plastic into the mold cavity, which is suitable for a single cavity and a single gate plastic mold; The multi-point hot gate is to branch the molten material into each hot gate sleeve through the hot runner plate and then enter the mold cavity, which is suitable for single cavity multi-point feeding or multi-cavity mold.
