Rotational Molding Machine Design

Product design students andrew duffy craig tyler and edward harrison built this cordless drill powered table top rotational molding machine in order to learn more about the process.

Rotational molding machine design. Our creative team provides product design prototyping tooling fabrication and management production feasibility and optimization along with vast finishing options to bring your rotomolding products to life sterling specializes in the production of a wide range of custom rotomolded parts and components and is capable of molding very intricate. This procedure can be broken down into two distinctly different functions which are product design and part design. In its simplest form one arm is being loaded and unloaded one arm is rotating or spinning in a gas fired oven molding the parts and the third arm is being air or water cooled. From agriculture to health care safety equipment to food service industry is turning to roto mold products to do the job.

Den hartog industries is capable of roto molding an endless variety of shapes sizes colors and materials. All necessary actions taken immediately by our technical experts to ensure quick fastest and reliable serivice. Rotational molding tolerates designs with undercuts inwardly or outwardly projecting walls that are parallel to mold parting lines better than most plastic processing techniques. Every product produced via the rotational molding process requires a mold or a tool.

The designing of a new plastic product to be produced by the rotational molding process is the same as designing a product for any other materials and processes.

We currently serve a variety of markets. Once the rotational molding design process is complete the next integral step to going into production is for a mold or tool for rotational molding to be completed. Rotational molding offers design advantages over other molding processes. Customer may contact directly to our technical support head for fastest service.

Sterling tech operates carousel type rotational molding machines with at least 3 arms with multiple molds positioned on each. The process also has inherent design strengths such as consistent wall thickness and strong outside corners that are virtually stress free. With proper design parts assembled from several pieces can be molded as one part eliminating high fabrication costs.
