Foam packaging materials are widely used nowadays, this is all you need to use the foam mold can be produced, in recent years because of the foam mould features such as light weight, good toughness, not easy to deformation, its development also is a good thing, but in terms of quality of machining foam mould needs to be improved, the following is the small make up for everybody finishing two Suggestions:

Suggestion 1: In order to discharge the gas and the residue of appearance gasification during pouring of foam mold, the straight runner should have enough height so that the metal liquid has enough pressure head to propel the metal liquid flow to fill the mold steadily and quickly, ensuring the casting appearance is intact and clear. In order to ensure that there is enough flow to make the pouring process it from time to time flow, and quickly set up the starting pressure head, can be used to a larger pouring cup; The straight runner is hollow to reduce air backflow and increase the pressure head at the beginning of pouring.

Recommendation 2: The use of negative pressure method can improve the stability of the casting, in time to remove the features generated during gasification pyrolysis gasification products. According to the size of the casting and the pyrolysis of the product, the negative pressure can be stopped during the pouring process, which can be well dealt with.

The above is to improve the quality of foam mold processing need to understand two Suggestions, in order to make the quality of foam mold become better, in the process of operation or need to pay more attention to.
