Swing nod of open flame rotomolding machine

There are three types of direct-fired swing machines: pit-type and pit-free pits, and nodding machines. It gives up the traditional connecting rod motor drive and hydraulic drive. The connecting rod drive is unstable and easy to damage; the hydraulic cylinder is difficult to maintain. This machine adopts the motor driven rack to realize the swing, which can adjust the angle arbitrarily, the transmission is stable and the maintenance is convenient.

1.a given quantity of plastic material,powder or liquid,islaid in one half of the mould

2.the mould is closed

3.the mould is rotated in the oven revolving on two axes.

4.plastic material melts,forming a coating layer on the mould internal surface.

5.the mould is removed from the oven and cooled off.

6.the mould is opened and the hollow item is extracted 

1. Low equipment cost
2. Rotational molding machine investment is less than other injection molding machines
3. The product surface is flat and the thickness is even
4. Suitable for large hollow products
5. The product is formed without pressure and produces a small amount of debris.
