The “PRH&C” is new technological engineering method capable of manufacturing products with high gloss, high brightness and high surface hardness with excellent transcription, whereby mold temperature is increased to be free from thermal deformation temperature, where high polymer resin is filled, and rapid cooling is exercised to improve fluidity of resin and to allow transcription to be excellently performed. The new engineering method of “PRH & C” has also eliminated welding lines to allow obtaining high quality products, and shortening the manufacturing period by more rapid heat exchange pace. The new engineering method is capable of maintaining the mold temperature on a further accurate uniform level in addition to features of rapid heating and rapid cooling, and minimizing quantity of heat that is leaked to outside by using close-loop method to thereby maximize thermal efficiency (There is no heat loss as the heat is recovered and re-used).
