How does the compression ratio in die structure be understood?What's the effect?
The compression ratio mentioned in the mold structure refers to the ratio of the cross section of the inlet of the mold to the gap section formed between the die and the core rod.With this can make the mould, melting certain compression ratio, which flows through the shunting cone the stented molten material can very good fusion seam, make the pipe is close-grained, ensure the strength of the pipe, the pipe molding quality guaranteed.
