The original equipment manufacturer companies always change their requirements according to the rapidly developing technologies. The most important challenge in the 21st century is achieving the zero-emission target. Lightening the automobile is the key factor to accomplishing zero-emission. For this goal, metal-plastic replacement has a significant role, changing the high-density metal to low-density plastic, compared to metal, without giving compromise about passenger safety is the most difficult factor. The constraints about plastic manufacturing method, the injection molding, limits the plastic using area on the automobile. Complex geometry such as the part includes two or more holes such as undercuts. These parts can’t be molded by injection molding. To cope with this problem, plastic welding methods are commonly used. The method is based on heating the part by friction and butting two parts under the pressure. Also, they are suitable for mass production and contrary to metal production cost, the method requires low investment. In the past, metals were mainly used on engine cooling system parts such as cooling pipes, thermostats, water pumps etc., but the presence of Polyphenylene Sulfide and Polyamide 66, plastic welding technology are marked an era about engine cooling system. In this paper, temperature effect of the ultrasonic welding was investigated. 40% glass fiber reinforced Polyphenylene Sulfide and %30 glass fiber reinforced Polyamide 66 were chosen to investigate ultrasonic welding properties by temperature effect as polymeric material.
