China High Stiffness Manufacturer, Supplier, Factory

Melt flow rate (referred to as melt index) is an important performance indicator of rotational molding materials, which has a significant impact on the processing and forming of rotational molding products.

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 August 7, 2025, our company officially signed a cooperation agreement with Xingzhi College of Zhejiang Normal University to jointly establish a practical education base, marking a solid step forward for both sides in deepening the integration of industry and education and collaborative education.Ruitang Technology has joined hands with Zhejiang Normal University Xingzhi College to jointly build a practical education base, opening a new chapter in the integration of industry and education On August 7, 2025, our company officially signed a cooperation agreement with Xingzhi College of Zhejiang Normal University to jointly establish a practical education base, marking a solid step forward for both sides in deepening the integration of industry and education and collaborative education. This cooperation aims to fully leverage the respective advantages of the school and the enterprise to create a high-quality platform that closely integrates industry, academia and research.

In the development history of rotational molding, there are two mainstream processing techniques, namely granulation process and dry mixing process. The overall process has significant differences, being two distinct pre-treatment methods for product processing materials.
