Hydrostatic extrusion of linear polyethylene in tubular and non‐circular sections

Abstract

Abstract Tubular and non‐circular section components have been produced by solid‐phase hydrostatic extrusion of linear polyethylene. Although the extrusion pressures were found to increase with the degree of complexity of the product sections, the module of the products were greatly enhanced and increased linearly with deformation ratio in the manner reported previously for circular section extrusions. Factors influencing the mechanics and stability of the process are discussed.
