They are lighter, safer and easier to clean. As well as this toy companies capable of designing and manufacturing toys and associated products find that they can be quickly brought to market at low cost during tight windows of consumer interest.
To capitalize on opportunities, cost-conscious toy companies are increasingly turning to rotational moulding (molding). Enticing product development allows skilled rotational moulders (molders) to produce high quality products in complex shapes with multiple walls and moulded-in fasteners and graphics without committing to excessive production runs. For instance, with movie toys such as ET or Star Wars, this enables toy companies to ship a wide range of products to market while movies are popular and minimizes inventory risk without incurring high up-front costs.
A wide range of toys are made with this process from the playgrounds at McDonalds to small pools and cars.
