The rotomolding machine is suitable for producing hollow parts of various complex shapes. During the whole process of roll forming, the raw materials are slowly coated and accumulated on the inner surface of the mold,

The rotational molding process is to first add plastic raw materials into the mold, and then the mold is continuously rotated along two vertical axes and heated,

1. From the global observation of the development of China's manufacturing industry, it can be seen that China's manufacturing industry has developed rapidly in recent years.

Analysis of the competitiveness of domestic CNC punching and die equipment At present, the domestic equipment produced by the domestic machine tool industry, except for a few high-end equipment that lacks the ability of independent innovation in China, and is difficult to meet for a while,
