TLDR
In this article, a computer-controlled heated-tool butt welding machine is used to determine the parameters of the welding process and a simple new method for determining these parameters is presented.Abstract:
Welding represents one of the key stages in the manufacture of injection molded or blow molded plastics products. One process frequently employed is heated-tool butt welding. However, the high seam quality associated with this process can only be attained through reliable process control and optimized welding parameters. This paper presents a simple new method for determining these parameters. Mathematical and physical descriptions of the individual process stages and a computer-controlled heated-tool butt welding machine serve as the basis for determining the parameters.read more
