  • A BETTER STAKING METHOD

    Dissatisfied with the conventional plastic staking methods of Hot-Air, Heated Punch, and Ultrasonic, Extol set out to develop a more robust and consistent method of heating and forming a molded stud or boss. Through the Extol product development group the InfraStake process was created and patented, and in the last 7-years thousands of modules and hundreds of systems have been serving in production in various industries. The advantages of a low impact, non-intrusive staking process are many. The consistency offered by InfraStake with its clean and efficient light energy have many of our users specifying “across the board” this process on all staking applications. Read More......

  • DESIGNING FOR ULTRASONIC WELDING

    While it is possible to ultrasonically weld plastic materials without specific joint design details, the weld process is greatly enhanced by adding proven features that aid in the process. For example, without a means of alignment built into the joint it is impossible to predict where the parts will be positioned after welding. This is due to the nature of the vibratory process created by ultrasonic welding. Read More......

  • Setup of Ultrasonic Plastic Welding Applications – Part 1

    Obtaining the optimum setup conditions for a given application using ultrasonic weld equipment usually requires a series of tests to determine the welding parameters that provide the best results. Although there is no solution for circumventing this testing procedure, a proper understanding of the principles and components of an ultrasonic assembly system will help to expedite the process of reaching the optimum setup conditions for a given application. To begin our understanding of the optimizing process, it is necessary to understand the basic components that make up an ultrasonic welding system. The system usually consists of six basic components. Read More......
