It can be understood as the flow channel of molten plastic from the injection molding machine nozzle to the end of the manifold.
Calculate the method of die casting mold runner:
1, for large products, after calculation, it is best to do a filling analysis, so as to ensure the success rate;
2, you can calculate the formula and calculation method according to the book, the results may be more persuasive;
3, can also be based on experience. We do molds, for general parts, is based on the quality to calculate the gate and runner moral area, general: gate area a = 0.18M mainstream channel area A = 3a, and then according to the different products and a few holes in the mold to the specific arrangement of the runner (applicable to 1Kg of products)
In short, in the practical application, knowledge is flexible!
You can avoid the mold and the machine does not match the problem. The total weight of the calculated runner can be used to calculate the cost, or to compare the loss of different runner programs. Production costing ... It can be used as a communication tool for up and down departments in the factory, providing specialized documents, Chinese interface, easy to use, engineers quickly come up with preliminary design solutions, reducing unnecessary.

Non-mainstream is alternative to let the public can not accept the meaning of dress, many people do not know what is considered non-mainstream, network material is also a lot of misnamed, referring to the deer for the horse, there are a lot of beautiful men and women of the network material in fact is not non-mainstream at all, but was released by the people who used the word improperly said that the non-mainstream, the reason is that a lot of publishers misunderstood the meaning of the non-mainstream, thinking that it is the trend of fashion, trend.
