| Summary: | This paper studies the comparison of flow analysis in
2-plate mould and 3-plate mould on an Electronic Cash Register
(ECR) plastic product using computer software analysis. There
are three parts in ECR plastic product which including top
casing, bottom casing and paper holder. Improvements on design
of gate, runner, sprue, water holes and plastic parts were made to
ensure optimum result analysis. This project started from design
all the three parts of 3D modeling in the Unigraphic software
and then transfer to Rhinoceros software for post processing and
finally used Moldex software as a final stage for flow analysis in
2-plate and 3-plate mould. In the Moldex software the filling melt
front time, packing melt front time, cooling and warpage analysis
were done to determine and to solve the part defects which
including short shot, unequal filling, over filling, welding line,
cooling time and measured the value of warpage. Some
calculations were done to determine the size of gate, runner and
sprue to ensure the smooth flow of plastic material into the
cavities area. In addition, calculations had been used for water
holes design, which based from the distance of plastic parts
surface to the distance of external diameters of water holes. This
project showed encouraging on analysis results for all the three
parts of ECR product. It solved various problems including short
shot, unequal filling, overfilling, welding line, cooling time and
measured the warpage value on the all three parts. |
