China LLDPE Manufacturer, Supplier, Factory

On August 29, 2023, Zhejiang Ruitang, as one of the organizers, jointly organized and launched the "Rotomolding Technology Festival National Tour" in Suzhou with Zhenhai Refining and Chemical, Wenling Xuri, and Shanghai Jiechuang.

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).

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;

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.

Considering the company's development and industry layout, our company has established "Ningbo Ruilai Powder Coating Co., Ltd." to specialize in the research, production, and sales of coated/lined plastics.
