The function of jacketing machine in the forming process of rotational molding products

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.

The rotational molding die is not easy to deform and deflect

Mold of rotary molding products the mold used for rotary molding is a single wall closed mold, which gives the outline of the product, but the internal outline of the product cannot be accurate to the details. Ordinary carbon steel plate is generally selected as the molding material of rotary mold. The cost of welding die is relatively low, especially suitable for large rotary plastic products. The rotary molding process has the following basic requirements for its mold:

How to solve the uneven wall thickness in the processing of rotational plastic products

In fact, plastic products with sudden change of wall thickness are not easy to be processed in the process of rotational molding. The average wall thickness of products mainly depends on the amount of feeding, and its uniformity is greatly related to the structure of the mold itself and the rotational molding process. If the uneven wall thickness occurs in the process of rotational molding, it is very likely that there are problems in structure, temperature and speed.
