Rotational molding, also known as rotational molding, is generally used for plastic processing and molding methods can not be formed, complex shape, difficult to make products, to meet the rapid development of today's society brought about by the various needs.
rotational molding process androtomolding productsThe advantages and disadvantages are closely related to the social application market, and the structure and size of the final product, the surface quality, the quantity of production and the efficiency of production are all direct factors.
rotomolding processingThe advantages of molding:
1. Design freedom, can be used to make a variety of complex hollow products
2. rotational mold cost is very low, the production cycle is short, suitable for batch, multi style production
3. You can switch raw materials and colors at will, which is conducive to the production of multiple varieties
4. Can achieve waste to produce small batch scale production, reduce waste and pollution
5. Can realize the molding of multi-layer products containing foam layer
6. High-performance products with various graphics can be formed
7. The production of large and super large parts save time and effort, low cost
8. Compared with blow molding, low difficulty, low cost, short cycle
9. Easy to shape products with rich appearance surface of marble and corrugated texture
rotomolding processingThe disadvantages of molding:
1. In the molding process, the need for multiple energy
2. It is generally difficult to form products with flat surface and large area
3. The molding cycle is relatively long
4. The surface smoothness of the final product that does not contact the mold is poor.
5. The largest amount of polyethylene molding after cooling shrinkage, dimensional stability is not good
The rotational molding process is relatively young in the development history of the plastic processing technology, and the overall scale is relatively small at present. However, due to various advantages, the rotational molding processing industry has become an extremely dynamic branch of the plastic industry.
