Thermal Analysis on ABS & HDPE Materials of Bonding Strength by Ultrasonic Welding

Ultrasonic plastic welding has received significant attention in the past few years, and has become more reliable and suitable for a wide range of applications. In recent years, technique has been extensively used due to the advent of component miniaturization and improvements in producing lightweight components. There are a number of advantages for ultrasonic plastic welding, including greater efficiency and speed, longer tool life, higher accuracy and no filler or flux needed to be used. Thus the technique can be viewed as being environmentally friendly In this work effect of various parameters on weld strength have been studied. Welding of 0.5 mm thickness Acryl nitride Butadiene-Styrene (ABS) and High Density Polyethylene (HDPE).plates were successfully welded by 20 kHz ultrasonic welding system. This experiment was carried to find out the optimum parameter for maximum strength. In order to determine critical states of the welding parameters, analysis of variances has applied while optimization of the parameters affecting the joint strength has achieved with centre composite method of the Response Surface Methodology. This study involves modeling of experimental data of joint strength of ABS & HDPE material for ultrasonic welding on welding parameters (welding pressure, welding time, and amplitude. Results are compared with Analytical values.
