Jacketed roll molding machines are mainly used to form large and extra large plastic parts. This kind of equipment uses jacketed roll molding molds. Its feeding, demoulding, heating and cooling are carried out in the same station, and its floor area is small. The heating and cooling of the mold of the jacket roll molding machine depends on pumping hot oil and cold oil into the jacket. It has high thermal efficiency and accurate temperature control. It is especially suitable for forming thick wall parts. Its disadvantage is that the equipment and mold are complex, difficult to process and expensive. The jacket type rotational molding machine is cooled by pumping cold liquid heat transfer medium (cold oil) and circulating through the jacket type.

1. The thickness of the rotational molding die is uniform and the precision is high, so that the thickness of the product is uniform and smooth;

2. Rotational molding mold is suitable for medium and large-scale rotational molding products;

3. Easy to repair and maintain;

4. The production cost of rotational molding die is relatively low;

5. The jacket roll molding machine adopts precision die processing method and rapid processing method to shorten the delivery time;

6. The structure of the rotational molding die can ensure that the rotational molding product is not damaged, and the surface can eliminate pores and trachoma.
