WHAT IS ROTO-MOLDING?

 

LifeArk components will be manufactured through rotational molding:

Rotational Molding, also called rotomolding or rotocast, is a thermoplastic process for producing hollow parts by placing powder or liquid resin into a hollow mold and then rotating that tool bi-axially in an oven until the resin melts and coats the inside of the mold cavity. Next the tool is cooled and the part is removed from the mold.

Four steps in manufacturing a rotational molded part:

1. Fill the mold with a polymer material

2. Heat & rotate tool in oven to melt material across mold surface

3. Cool tool to solidify the part

4. Remove part from the tool

Rotational Molding Advantages:

  • Design flexibility allowing complex geometry
  • Low-Tech process 
  • Tooling cost are less then other plastic molding methods
  • Parts offer strength, corrosion resistance and durability
  • Short lead times on production
