ABOUT Rotational Molding
Technology Rotomolding (Rotational Molding) Services are plastic molding services which use a zero pressure process for producing hollow products. Resin, loaded into a closed mold, is heated as the mold slowly rotates on two perpendicular axes. The resin adheres to the mold surface, coating the surface evenly. The mold continues to rotate while it is being cooled, maintaining even wall thickness. Rotomolding is a fairly economical process for producing large hollow objects such as tanks, ice chests, etc.
Advantages: Rotomolding services are able to produce large shapes that have few details on their surfaces.
Can produce thicker walls than either blowmolding or injection molding
Suited to low volume, high value products
Pressureless process makes tooling economical
Exterior corners are strong and stress free
Limitations of Rotomolding Services
Cycle times are relatively slow, cooling times long
Materials more costly due to need for additives and ground powders
Limited material choices
Ribs, etc. are difficult to produce
Applications: Rotomolding services are particularly suited to producing large, shell like objects with thick structural walls and reinforcing ribs.
