At present, the intelligent power grid project is flourishing, and the construction of distributed power stations is also vigorously promoted, which puts forward higher requirements for the electrical safety performance of high-voltage cable joints. The original conventional coating materials can no longer meet the higher performance requirements of flame retardancy and voltage breakdown resistance.

Many domestic rotational molding product companies have always relied on a certain rotational molding material from Thailand to meet their requirements for good whiteness and minimal deformation of their products, without any further options.

On July 4th, Dongguan, Guangdong became a focal point for rotational molding technology. Our company, together with Sunrise Rotational Molding, Shanghai Jiechuang, and Zhenhai Refining and Chemical, held the 8th Rotational Molding Technology Festival. From morning till night, the venue was lively and filled with an atmosphere of exchange and learning.

Good thermal conductivity not only refers to the good thermal conductivity of the embedded parts, but also the good thermal conductivity of the embedded screws. Most of the parts connected by the embedded parts transfer heat from the threads and the inner wall of the mold;

Rotomolding HDPE, short for rotationally molded high-density polyethylene, is a specialized thermoplastic material used in the production of large, seamless, and durable hollow products. The rotomolding process involves heating powdered HDPE resin inside a rotating mold, ensuring even material distribution and the formation of stress-free structures. This technique has gained immense popularity across industries such as automotive, agriculture, marine, and chemical storage due to its ability to produce complex shapes with exceptional strength and longevity.
