Title: QUALITY ASSURANCE OF COMPUTER-CONTROLLED HOT-TOOL WELDING FOR MASS-PRODUCTION
Author: POTENTE, H; NATROP, J
Abstract: The hot-tool welding process is commonly used for welding plastics, but high seam quality can be obtained only by optimizing weld parameters. Because of demand for better quality, the importance of quality control is increasing. At present, quality control is mainly performed by inspecting the end product, resulting in high scrap rates. An effective quality control system must therefore be able to recognize errors as they occur during the manufacturing process. For this, an FMEA (Failure Mode Effect Analysis) should be performed prior to mass production, and statistical quality control should be implemented during and after the process. This paper describes a quality control system for computer controlled hot-tool welding that is based on an understanding of the physics of the process.
