Hollowrolling

Hollowrolling is a term that describes the act of intentionally creating a deliberate gap or hollow space within a manufactured object during its production. This technique is employed across various industries for a range of purposes, primarily to reduce material usage, decrease weight, or enhance specific functional properties. For instance, in the production of pipes or tubes, hollowrolling results in a hollow core, saving on the raw materials that would otherwise fill that space. This also leads to a lighter final product.

In the manufacturing of certain plastic components, hollowrolling can be used to create internal air pockets. These air pockets can act as insulators, either thermally or acoustically, depending on the application. For some metal components, the hollow space can be used for internal routing of wires or fluids, or it can be filled with other materials to achieve a desired density or vibration-dampening effect. The process itself typically involves specialized machinery and molds that are designed to leave a void during the shaping or forming stages. The exact method of hollowrolling varies significantly depending on the material being worked and the desired final product characteristics.
