Method for producing hollow objects made of thermoplastic material

摘要

The tank has a multilayer tubular extrudate obtained using an extrusion head (2) and separated into two sheets (1) using blades (3). The sheets are guided and moved using rollers (4), and two mold parts (7) are placed under the extrusion head. A preassembled structure (5) carries an accessory and is anchored on an internal wall of the tank. The accessory, between the sheets, does not present interface with the external atmosphere.
