How will the glue line be handled in the process of precision mold making? |
In the process of precision mold making, there will be a kind of glue line. It is raw material in the confluence produces fine line, as a result of not total integration, the finished product in the same place on positive and negative of fine line, if the mold side temperature is high, and its contact will glue line than the other. So how do you deal with that?
First, raise the raw material temperature, increase the injection speed will reduce the glue line.
2. Increase the mold temperature and increase the flow of raw materials in the mold. When the raw materials meet, the temperature is higher, so that the glue line will be reduced.
3. The position of CAT will determine the position of the glue line. Basically, the position of glue line will be in the same direction.
4. There is oil or other non-volatile components in the middle of the mold, and they are concentrated in the junction where the fusion is not sufficient and the glue line is formed.
In addition, attention should be paid to the influence of die structure, will completely eliminate the glue line is not possible, so the machine don't constraints in terms of removal will glue line, it will be unhealthy phenomenon produced by glue line control of minimal, it is more important.

Down：There are several problems to be paid attention to in precision mould processing.
Up：Double-color injection mold should be checked before use. |
