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.

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, 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;

With the global emphasis on energy conservation and emission reduction, plastic fuel tanks are gradually replacing traditional metal ones due to their light weight and high efficiency.

In the previous episodes, our company's manager Mr. Wang shared the content about the current situation and trends of the European injection molding industry at the ARMO annual meeting.
