Many things in our lives are made of molds, including many plastic electrical appliances, which are also made of plastic electrical appliance mould . Today we will take a look at the balance of mold gates.
If the balance of the gate cannot obtain a balanced runner system, the following gate balance method can be used to achieve the goal of uniform injection molding. This method is suitable for molds with a large number of cavities. There are two ways to balance the gate, changing the length of the gate channel and changing the cross-sectional area of ​​the gate. In another case, that is, when the mold cavity has a different projected area, the gate also needs to be balanced. At this time, to determine the size of the gate, you must first determine the size of one of the gates and find its corresponding The ratio of cavity volume comparison, and applying this ratio to the comparison between its gate and each corresponding cavity, the size of each gate can be obtained one after another. After the actual trial injection, the balance of the gate can be completed. operating. 
The Plastic Child Product Injection Mould is used by children more often, so more attention should be paid to the selection and balance of the sprue.
