Brief analysis of rotomolding blow molding machine

For complex shaped hollow products that are difficult to form by other forming methods, the use of rotomolding hollow molding has obvious advantages, and this molding method has great development prospects especially in the chemical industry. This is because all thermoplastic powdered plastics can be rotationally molded and expanded into the field of cross-linking and thermoset plastics.


The overall technical development trend of the rotomolding blow molding machine is to develop toward automation and high speed. In the heating method, the hot air circulation method and the open flame heating method are developed in the direction of the heating system which can be automatically controlled, such as the oil jacket heating method, the molten salt heating method, and the infrared heating method. At present, a variety of multi-layer rotational molding hollow molded products for automobiles have been developed. For example, multi-layer rotomolded fuel tanks are comparable in cost and performance to multi-layer co-extruded fuel tanks.

U Nails

U nails refer to a kind of fasteners with two-pronged shanks. These U nails are usually used for attaching the mesh fences to wooden posts and frame, hence the name fencing staples. These practical nails can fix the wire, rope even Barbed Wire to the ground, wooden post or stakes. Therefore, people like to use them in agriculture & gardening, viticulture & other fruit growing, animal coops & plant trellises construction.
