The High Frequency Welding Aptitude of Thermoplastic Polymers

The debates study the influence of the molecular structures for polymers welding and establish the conditions when is possible to obtain a welding joint of these and a transition area near welding with properties which ensure good usage. The testing of aptitude of materials for high frequency (HF) welding, were done with Polyvinyl Chloride (PVC) foils with textile insertion and Malivat materials, defining in an experimental way, the optimum process parameters which ensure a good resistance breaking for welding. Key words: polymer, structure, welding ability The usage of plastic materials in industry suffered an important increase in the last 50 years, and development of new welding technologies of these materials was the main focus. This development is an effect of these new components asked in design phase in the innovative fields as medical, automotive and packaging industry [2, 5]. In this direction, the welding of thermoplastic materials with HF proceed is a field with a big interest in production and manufacture
