1、 What is roll forming?

Rotational molding, also known as rotational molding, rotary molding, rotary molding, etc., is a technical method for hollow forming of thermoplastic materials. Can be made into various shapes, sizes, and colors (both inside and outside) of plastic products. The product features integrated molding and can be manufactured with triple layers of foam as needed to enhance the strength of the barrel. The product is lightweight, tough, has strong impact resistance, and excellent drug resistance, making it a rare plastic processing and molding method.

2、 The production steps of rotational molding products

First, break the raw materials into powder or liquefied polymer state, and then put them into the product mold for heating. At the same time, the mold is fixed for rotation and revolution. When the raw materials fully and evenly cover the inner surface of the mold, when the product reaches the gel point, it is cooled and molded, taken out, placed in the working area, trimmed the product, and then tested whether the product meets the warehousing standard.

3、 Common roll forming products

Plastic water tank, water tower, dosing tank, plastic fishing boat, pickling bucket, plastic storage tank, etc.

4、 Applicable industries

1. Plastic water towers, mixing drums, and other containers commonly used in chemical plants to store chemical raw materials and finished products.

2. Containers for food processing, pickling, and processing.

3. Plastic water tanks for aquaculture and frozen storage of seafood.

4. Plastic fishing boats used for salvage and dredging work.

5. Containers for storing synthetic drugs in the medical industry.
