MOLDING MATERIAL AND MANUFACTURE AND DEVICE THEREOF |
摘要 |
The present invention concerns an apparatus and process for producing an improved extruded plastic material product which consists of an inner foamed thermoplastic cellular core and an outer non-porous thermoplastic skin extending along at least one side of the core. In the process, a foamable thermoplastic material is extruded through a first die outlet to produce a foamed thermoplastic material. After exiting the die outlet, a film of non-porous thermoplastic material is applied along at least one side of extruded foamed material. Next, the extruded foamed material and the non-porous film is fed through a forming die which shapes and seals the materials into the desired cross-sectional shape. |
