Analysis on Hot Plate Welding of Thermoplastic Elastomer Packing

An Experimental Study on Effects of Hot Plate Welding Parameters on Toughness Energy and Tensile Strength in Weld Line of Thermoplastic Parts

Integral production of the thermoplastic parts with complicated geometric shapes by the processes such as injection molding and extrusion is not economical. It is better to divide the final shape into more simple parts and after production join them by an appropriate welding process. This research aims to study the tensile strength and toughness energy of high- density polyethylene parts which ...

Enhanced Coarse-Graining of Thermoplastic Polyurethane Elastomer for Multiscale Modeling

The objective of this work is to develop a multiscale modeling tool of copolymers with long chains. We propose an enhanced coarse-graining method of thermoplastic polyurethane (TPU) with three beads. The proposed coarse-graining provides an accurate molecular modeling tool to keep the molecular interaction together with computational efficiency. The coarse-grained model with three beads is furt...

Measurement of Thermoplastic Dynamic Modulus using an Ultrasonic Welding System

This paper reports the preliminary results of a newly developed method for measuring dynamic modulus of thermoplastic materials at a given ultrasonic frequency. In the method, a material specimen is squeezed at the tip of the horn of a conventional ultrasonic welding machine. The mechanical impedance of the material specimen under loading is then deduced by processing the input electrical imped...

Microwave facilities for welding thermoplastic composites and preliminary results.

The wide range of applications of microwave technology in manufacturing industries has been well documented (NRC, 1994; Thuery, 1992). In this paper, a new way of joining fibre reinforced thermoplastic composites with or without primers is presented. The microwave facility used is also discussed. The effect of power input and cycle time on the heat affected zone (HAZ) is detailed together with ...
