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).

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.

Today, we are going to explore the coating problems encountered in the rotational molding process of plastic fuel tanks and their solutions.
