As a professional Rotational Molding solution provider, Rising Sun Rotomolding has now extended its rotational molding equipment solutions to over 40 application industries, covering more than 200 product categories, with countless segmented products tailored to specific customer needs. Our rotational molding technology is widely recognized for its ability to produce durable, hollow plastic components—an advantage that makes it ideal for manufacturing high-performance cleaning products.

Before the test, the technical team conducted a detailed inspection of all core components of the equipment, from the temperature control accuracy of the heating system to the transmission stability of the rocking mechanism. Every detail was strictly calibrated. Meanwhile, raw materials for trial production were prepared according to standard proportions, ensuring the entire testing process runs smoothly and without errors, laying a reliable foundation for subsequent tests.

Traffic facilities are a key application field for the development of the rotomolding industry, with its core products including:

The selection of rotational molding molds is a crucial link in the rotational molding process. The material, thickness, craftsmanship, and structure of the mold will directly affect the quality of rotational molding products!

As is well-known, steel corrosion is extremely common, and the economic losses caused by it are also enormous; while pure plastic parts are inferior to steel in terms of impact resistance and puncture strength, and common plastic pipes are also prone to damage during various construction processes.

Steel-lined plastic technology perfectly combines the high-strength advantage of steel and the multiple characteristics of plastic materials. It is widely used in transmission and storage components such as steel-lined plastic storage tanks and pipes. Among them, the service life of high-quality steel-lined pipes can usually reach more than 50 years!

Molding Process
Many rotational molding products require secondary or even multiple feeding during the production process! How to conduct secondary feeding safely and effectively has always been a research topic for us!

In recent years, with the strong support of China for the environmental protection and new energy field, the hydrogen energy development industry has entered a new stage of development! As a key link in the hydrogen energy industry chain, hydrogen storage tanks, relying on their good design adaptability and mobility, have successfully met the core requirements of daily transportation and assembly. At present, the development of domestic hydrogen storage tanks is still in the initial exploration stage, and there are still many technical problems to be solved. Relevant industry standards also need to be further formulated and improved, which is undoubtedly an emerging field with great development potential!  

Refrigerated insulation boxes are a key application field of the rotomolding process. With core advantages of durability, friction resistance, and strong thermal insulation performance, they are highly favored by customers!

In today’s complex and ever-changing production environment, workplace safety is of paramount importance. To further strengthen employees' fire safety awareness and enhance their ability to respond to emergencies such as fires, Wenling Sunrise Rotomolding Technology Co., Ltd. once again meticulously organized and conducted a comprehensive and in-depth fire drill.

Meeting Background:
On May 16, 2025, Wenling Sunrise Rotomolding Technology Co., Ltd., as the Vice Chair Unit of the Rotomolding Committee of China Plastics Processing Industry Association, was invited to attend the 2025 Rotomolding Annual Conference of the Rotomolding Committee of China Plastics Association. This conference brought together domestic rotomolding industry experts, enterprise representatives, and related organizations to engage in in-depth discussions on core topics such as technological innovation and civil-military integration.

Wenling Sunrise Rotomolding Technology Co., Ltd. consistently regards employee health as a core driver of corporate development. Recently, the company successfully completed its annual occupational health check-ups, once again demonstrating its commitment to employee well-being through action.

Ricky stood in his factory, gazing at a row of rotomolded products. Some were in perfect condition—with smooth parting lines, uniform wall thickness, and consistent coloration. Others, however, displayed obvious defects: air pockets, warpage, and excessive surface porosity. He sighed inwardly.
