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.

Ultrasonic welding is an industrial method where high frequency ultrasonic acoustic vibrations are applied to workpieces that are held together under compression to create a solid state weld. Ultrasonic welding is commonly used for plastics, and especially for joining unrelated materials. In ultrasonic welding, there are no connective rivets, bolts, nails, soldering materials, or adhesives required to fix the materials together.

Once the benefits of heat staking, or thermal presses, are well understood, developing a solid part design and selecting the appropriate piece of thermal press equipment to do the job is the next step. Select a product to find specifications for our thermal press machine systems, pneumatic and hydraulic presses, and ultrasonic tooling. Toman ThermosSonics, Inc. designs and manufactures a range of equipment, from bare bones units to fully automated systems, with tooling and automation accessories.

Toman ThermoSonics, Inc. has a combined experience of over 75 years designing and building semi- and fully automated custom production systems. From laser marking, degating and assembly systems to Multi-Zone Thermal Press Machines and Heat Staking and heat sealing systems, Toman has the ability to provide all necessary mechanical, power and control system designs to efficiently automate assembly processes involving thermal-based solutions.

What is a Thermal Press Machine?

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.

Several configurations of plastic boss designs are available, each with specific features and advantages. The selection of a heat staking plastic boss is determined by such factors as: composition of the plastic, component geometry, final assembly requirements, machining and molding capabilities and cosmetic appearance. Proper design of this component will produce optimum strength with minimal flash.

The thermal press assembly process comprises a significant share of the following sectors, but NOT limited to:

  • Aerospace
  • Automotive
  • Consumer Products
  • Medical Device
  • Medical Test
  • Telecommunications
