Meeting the diverse needs of our customers has always been our unremitting goal. For the insulation box industry, we have integrated our various resources and now have the ability to provide a series of customized supporting products for insulation box production enterprises:

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 May 16, 2025, our company participated in the "China Plastics Association Rolling Plastic Special Committee 2025 Annual Meeting" held in Xingtai, Hebei Province.

At present, in the selection of inserts, most of them use: 1. brass; 2. Zinc aluminum alloy; 3. Stainless steel (anti-corrosion, corrosion-resistant);Defect Solution | Rolling Plastic Fuel Tank Science Popularization -2- Principle and Solution of Coating Problem ② Temperature and Embedded Parts (Expert Article) At present, in the selection of inserts, most of them use: 1. brass; 2. Zinc aluminum alloy; 3. Stainless steel (anti-corrosion, corrosion-resistant); The basic components of embedded assembly are: 1. Embedded screws; 2. Mold cavity wall; 3. Embedded components; Material selection for inserts: 1. Good thermal conductivity; 2. Sufficient mechanical strength (details will be elaborated in the next section).

Linear low-density polyethylene (PE-LLD) was selected as the base material. The melt blending was carried out by a twin-screw extruder, and the powder material suitable for rotational molding process was prepared by using a mechanical grinding mill.

During the eight-day extension, we had in-depth exchanges with many international clients. This journey not only brought orders, but also a global perspective and trust. Ruitang Technology, with its unceasing pace of innovation, looks forward to meeting again on the world stage next time
