The advantages in roto-moulding process:

 

1.   One-piece construction: virtually stress-free enclosed parts or with openings

2.   Design flexibility from various size and shapes.
3.   Economical for short production runs, prototype research and volume production

4.   Variety of finishes and color

5.   Metal inserts as integral parts

6.   Weight reduction as compared to most metals.

7.   Excellent load-bearing properties

8.   Ability to produce multi-wall moldings, hollow or foam filled

9.   Minor undercuts are possible with no draft angles required

10.   Thickness can be varied if required

11.   Cost saving - economic tooling costs

12.   Uniform wall thickness no thinning in the extremities
