Plastic storage tanks, also known as PE storage tanks, plastic water towers, plastic water tanks, PE barrels. Used for outdoor water storage, industrial water storage, chemical raw material storage, food industry fermentation and so on. The main advantages of this product are the advantages of corrosion resistance, UV protection, high and low temperature resistance, and long service life in the industry. Today, I mainly talked about the production process of plastic water tanks (rotation molding process).

1. The rotomolding process originated in foreign countries. The early technology in China's mainland was mainly imported from Taiwan. As the rotomoulding equipment is cheap and easy to produce, the use environment has been widely promoted and developed rapidly in mainland China in the past 20 years. Currently, it covers almost all large and medium-sized cities in China.

2, rotomolding process is a special plastic processing technology, we all know that plastic processing molding process is very many columns such as: extrusion, injection molding, blow molding, and so on. We all know that these processes have one thing in common: the external heating of the internal pressure, the material is pressed into the mold to form. This makes the product highly brittle.

3, rotomolding is a rotation molding, the temperature reached 165 degrees plastic powder began to melt. The temperature of rotomoulding does not exceed 180 degrees so the product melts at a very uniform rate. The mould rotating material slowly melts. The product has a very uniform wall thickness and is very smooth inside and outside.

4, rotomolding process in the previous years, mainly for large plastic tanks. In recent years, our country has introduced advanced rotomolding aluminum mold production technology from Germany. Slow rotomolding can also be used for small-sized products to make small, rotomolding plastic products that are beautiful and durable.
