optimize your product for production in the rotational molding process


Sterling's OneSource plastics engineers will optimize your product for production in the rotational molding process. The rotomolding process offers unique advantages to other plastic processes, and to take advantage of those benefits most product designs require some early stage refinements.

Some of the things our group will focus on are ways to reduce cost, shorten production cycles, minimize or relocate seams, simplify and speed assembly, strengthen walls and corners, improve rigidity, enhance textures, add thermal value, locate graphic placement, and simply help improve the product’s basic design or function. 

Our engineering and tooling services are offered without any obligation of production.

THAT’S RIGHT... whether you choose to use our molding services or not, we’re happy to help bring your product life. 

Our engineers take advantage of SolidWorks 3D Modeling Software to design components and parts. It's the plastics industries' most widely used software.

Below are samples of products engineered through Sterling OneSource Team.
