De anvan tout koreksyon materyèl likid itilize nan pwosesis la RIM te ki estoke nan de rezèvwa nan tanperati sèten, rezèvwa se souvan veso presyon. Nan bòdi, stoste anjeneral nan 0.2 ~ 0.3 MPA ba presyon nan rezèvwa a, ak sikile toujou ap nan rezèvwa a, echanjeur chalè ak melanje tèt yo. Kòm pou an poliyiretàn, tanperati an mwayèn nan stoste se 20 ~ 40 ℃, presizyon nan kontwòl tanperati se ± 1 ℃.

Two raw liquid material used in the RIM process were stored in two reservoir at certain temperatures, reservoir is commonly pressure vessel. In molding , stoste usually in 0.2 ~ 0.3 MPa low pressure in the reservoir, and circulating constantly in the reservoir, heat exchangers and mixing head. As for polyurethane, the average temperature of stoste is 20~40 ℃, the temperature control accuracy is ±1 ℃.
