What are the products produced by rotomolding mould?

Using rotomolding moulds is a production process for forming hollow parts of infinite size. This is a cost-effective method of producing large plastic parts. The resin is added to the mold, which is slowly heated and rotated vertically and horizontally.

What is the function of the rotomolding mould in rotomolding process?

Standard setup and equipment for rotomolding

Usually all rotational moulding systems include rotomolding mould, oven, cooling chamber and mould spindle. Molds are used to make parts, usually made of aluminum. The quality and finish of the product is directly related to the quality of the mold used. The oven is used to heat the part while rotating the part to form it as desired. The cooling chamber is where the part is placed until it cools, and the spindle is mounted to rotate and provide an even coating of plastic inside each rotomolding mould.

What are the production advantages of using rotomolding mould?

Rotational molding is a high-temperature, low-pressure plastic molding process that uses heat and biaxial rotation (that is, angular rotation in two axes) to produce hollow, one-piece parts. [9] Criticisms of the process point to its long cycle times - typically only one to two cycles per hour, while other processes such as injection molding can produce parts in seconds. This process does have clear advantages. It is much easier to manufacture large hollow parts, such as fuel tanks, by rotational molding than any other method. Rotary rotomolding mould is much cheaper than other types of moulds. Very little material is wasted using this process, and excess material can often be reused, making it a very economical and environmentally friendly manufacturing process.

What are the products produced by rotomolding mould?

From the product level, the rotomolding products produced by rotomolding mould have developed from ordinary civilian products to key industrial products, and their functions have also changed from single container performance to structural performance. With the development of rotomolding equipment and molds, the structural complexity of rotomolding products has developed to an unimaginable level. It can even be said that products that cannot be completed by injection molding, blow molding, extrusion molding and other processes can be completely completed by rotomolding. , The geometric size of the product has been completely able to achieve from 0.5L to 50M3. It can be even bigger if it is not limited by shipping conditions. From the classification of the products, it can be roughly divided into cylindrical water tanks (0.25M3~ 50 M3), circular truncated open buckets (20L~3000L), and square open buckets (30L~2000L). Shaped into various types of closed containers to meet the needs of different industries.
