Flow simulation of the two-component plastic injection process with reinforced parts

Mîndru T. T., Ciofu C., Nedelcu D.

Wybrane Problemy Inżynierskie

2011

nr 2

261-266

This paper presents a simulation of two-component injection process for obtaining plastic parts with metallic reinforcement using a specific software package, MoldFlow. It will consider the following process parameters, mould temperature and injection pressure. The study will analyze the comparison between plastic parts with and without metallic reinforcement. It will highlight the differences that occur between the input parameters, mould temperature and injection pressure and the out parameters, cooling time and injection time for those types of parts obtained. Furthermore will be simulated a mechanical stresses of traction using a specific software package, Cosmos, for both parts obtained.

In this work authors presented the restrictions and possibilities of permanent mould casting technique in manufacturing dispersive composite elements reinforced with metallic particles. The characteristic feature of such particles is their physical and chemical reactivity, which deteriorates the rheological properties of the liquid dispersion. Selection of technological parameters for manufacturing and casting is aimed on proper filling of the mould with liquid dispersion. For comparison, the results of similar experiments with use of investment casting were shown. Basic constructional requirements connected with brake discs manufacturing were presented, together with the concept of moulding materials selection, influencing the flow of liquid dispersion. As the results of conducted studies technological parameters of brake disc manufacturing with use of AlSi-CrxCy composites were determined.
