Effects of Geometric Characteristics on Flow Ratio of the Melt and Modifying the Checking Formula
The melt fluidity of the two typical plastic, including polypropylene (PP) and polyethylene(PE), are studied in the different mold with the different characteristics of channel cross section and channel profile for the fluidity test of the melt. The relationship among the flow ratio, characteristics of channel cross section and channel profile are analyzed. The modified law of the flow ratio was proposed on the basis of the experiment, and discussed in detail. The results are better based on the experiment analysis, and the checking formula of the melt flow ratio could be used to check the designed mold in production.
