Abstract

Abstract: Using filling and flowing balance modules of Moldflow, unbalanced flowing of double-color toothbrushes injection mould with hot runner was analyzed. By adjusting section sizes of runners, good flowing balance was obtained: in first injection molding, the unbalanced filling ratio was decreased to 1.7% from 38.2%, and the unbalanced pressure ratio was decreased to 4.1% from 39.6%; unbalanced filling ratio and unbalanced pressure ratio was 0.37% and 4.5% separately for second injection molding. Main process parameters were determined, including injection time, injection pressure, melt temperature and mould temperature.

Key words: hot runner, double-color injection, flow balance, process parameter, mould
