Recycling process of melted resin after the injection molding is getting popularto reduce the waste of material. It uses two rollers to make the remaining resin into plastic panels. Analysin the thermal/fluid behaviour of the melted resin is important in the roller process. For this the flow analysis of the gravity driven resin has been done between the rotating rollers with constant speed. The temperature of the roller surface which was contacted with resin and the ambient air cyclically was obtained and it was used as the thermal boundary conditions for the thermal behaviour of the resin. The obtained steady-state results showed a reverse flow in the central part in between the rollers. The temperature of the plastic surface was reduced sharply to the one of the roller surface after it was temperature change was slow inner part of the resin due to the phase changing process.
