Explore how blow molding and rotational molding relates to chapter three overall and learn about each.
- Rotational molding and blow molding…are methods we've over viewed a little bit,…but now it's time to talk specifics.…In rotational molding,…plastic powder is measured into the mold,…and the entire mold is placed in a heating oven.…The machine then rotates the mold…along one or more axes,…letting the material coat all of the walls…to a nominally even coating.…Rotational molding is well suited…for vessel containers for liquids,…and for parts that have specific outside…measurements required.…
The benefit of this method is primarily cost,…as it's cheaper than injection molding.…Rotocast parts are a great choice…for parts that don't have interior geometry,…and don't have strict wall thickness requirements.…Rotoparts can be robust and have a reduced tooling cost,…though sometimes the material cost per unit is higher.…Rotomolded parts can be entirely self contained,…meaning they don't have to be assembled later.…Rotopart tooling still has to follow mold guidelines though.…
