Toman Thermosonics Inc.

We are an innovative, full service manufacturer of high quality, affordably priced thermal presses or heat staking machines as well as ultrasonic welding accessories and supplies designed to meet the thermoplastic assembly needs of the plastic product engineering industry. Toman’s thermal presses accurately control time, temperature, pressure and cooling for optimum component assembly – no matter the size of components being heat staked together. Toman’s plastic heat staking equipment are comprised of a microprocessor-based temperature controller with digital display of set point and process value readouts for multi-point assembly operations. Toman’s thermoplastic processing equipment is exceptional for the following applications: • Assembling plastic to other materials • Inserting metal into plastic • Branding imagery into multiple materials • Date coding plastic parts • Degating injection molded parts • Sealing thermoplastic material Toman is the industry leader in the design and manufacturing of thermoplastic processing equipment. Services Include: Manufacturing Engineering Off-Line Repairs Short-Run Prototype Work Testing New Applications 3D Printed Fixtures Laser Etching Assembly Production Thermal press machines, frequently referred to as heat staking systems, are designed to permanently bond several separate parts into a complete assembly. The technology is a very reliable assembly method that offers a number of advantages over other bonding processes. Low thermal press machine cost, long-lasting tooling, stronger bonding and quiet operation are but a few of these system’s benefits. A thermal press machine, also know as a heat staking machine, or plastic assembly machine, is used as a fastening process to mechanically assemble two components together. One of these components needs to be made of plastic, or more specifically a thermoplastic. In the thermal press machining process, the plastic workpiece has a “boss”, or protruding stud, while the second component has a hole that receives this stud.  While placed in the thermal press machine, high temperature and force are applied to deform the stud and create a stake. This stake then retains the second component, eliminating the need for rivets or screws that can become faulty and break over time. After the formation of the stake, cooling the plastic ensures component bonding.
