1. User can measure real mold temperature
2. User can check temperature change from heat conduction, when resin of high temperature is flowed in, and between heating and cooling
3. Molding condition can be found easily conforming to change of outer temp. variables (Atmospheric temperature, scale creation in cooling channel)
4. User can check easily whether cooling if fast or slow
5. Molding condition can be standardized so that uniform quality product is possible from the first shot
