1.
Selection of rotational molding die. On the same rotary molding machine, if conditions permit (there are enough molds of the same type), it is best to choose the molds of the same type; If you want to produce different kinds of other products at the same time, when choosing rotational molding dies, try to install dies with similar volume and size, and the weight difference should not be too big, and the thickness requirements of rotational molding products are basically the same. In order to avoid the phenomenon of product aging degradation or residual plastic powder. Because different rotary molding dies need different processing cycles.
2.
Installation spacing of rotational molding die. How many molds should be installed on a mold support? This should be calculated first, and there should be enough distance between molds to avoid shielding each other, which is beneficial to the conduction of hot air and the opening and closing of molds.
3.
Grasp the center of gravity of mold support. We must pay attention to this. If the bracket is heavy and light, it will affect the rotation of the rotary molding machine, resulting in uneven thickness of the product, which will seriously damage the rotary molding machine.
4.
Pay attention to the oven diameter of rotary molding machine, and calculate the rotation range when installing the mold, otherwise it will bring bad consequences.
5.
Fixation of rotational molding die. When installing the mold, we should not only consider the firmness, but also consider the speed of installation and disassembly.
