Thermoplastic elastomers are being used increasingly throughout industry owing to their superior properties, such as superior elasticity, formability, and recoverability. Currently, research related to thermoplastic elastomers is focused on the development of composite elastomers by combining with various materials and the development of equipment. On the other hand, in the field of small and medium sized companies, it is necessary to study not only the application of these new materials, but also the process conditions that enable the extrusion of thermoplastic elastomers in inexpensive uniaxial screwing equipment. If extrusion is performed in a single screw extruder, it is important to maintain a uniform thickness through process control of the extruder. This study examined the effects of the processing temperature, which is an extrusion process variable, on the formability of a tube in the thermoplastic elastomer TPE-800L uniaxial extrusion process. The nozzle zone temperature is the most important factor in the extrusion of thermoplastic elastomer TPE-800L; the most excellent moldability was confirmed at $165-170^{\circ}C$.
