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.

Rotational molding is shaping the future. Rotational molding offers design advantages over other molding processes. All necessary actions taken immediately by our technical experts to ensure quick fastest and reliable serivice. 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.

The process also has inherent design strengths such as consistent wall thickness and strong outside corners that are virtually stress free. Den hartog industries is capable of roto molding an endless variety of shapes sizes colors and materials. India roto plast is the fastest growing manufacturer exporter of rotational moulding machine roto moulds and ancillary equipments.

With proper design parts assembled from several pieces can be molded as one part eliminating high fabrication costs. It is critical that the molds be designed accurately and completely for the process in effort to keep the process efficient and on track. 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. This procedure can be broken down into two distinctly different functions which are product design and part design.

We currently serve a variety of markets. 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. Rotational molding tolerates designs with undercuts inwardly or outwardly projecting walls that are parallel to mold parting lines better than most plastic processing techniques.
