    Heat Staking processHeat Staking is a pulsed heat process to join two or more parts out of which one at least is made of plastic. The process is to deform the plastic material using heat and force at a set process time. The bond is made by partially de-forming the plastic part in order to fix the other. Heat Staking makes it easy to bond metal to plastic and is commonly used in high volume/low cost applications like automotive, IT and consumer appliances.

    Shaping Plastic Using Heat and Pressure
    De-forming the plastic is achieved by heating it to a temperature above the glass transition temperature via the use of super-heated air or a thermode and then applying pressure in order to create the stake. After the stake has been formed the plastic should be cooled down again below the glass transition temperature. This cooling is done under constant pressure to ensure good fixation of the parts. Cooling can be done with the use of compressed air when using a thermode.

    Heat is used to make it easier to create the stake. Heat control is critical, especially for glass filled plastics which often have a process window smaller than 10 degrees Celsius. When temperatures are to high the glass fibers come out of the plastic leading to a rough surface and sticking to the thermode. If the temperature is too low the plastic will crack due to cold deformation.

      Heat Staking Benefits:

    • Similar and dissimilar materials may be joined: metal to metal, plastic to plastic, metal to plastic

    • Accurate control operating within a small process window

    • Local heating resulting in no damage to surrounding materials

    • Processing of glass-filled materials

    • No mechanical vibration

    • Many heatstake shapes possible through custom designed tools

    Our proven technologies enable the Automotive, IT & Multimedia, Electronics & Solar Cells, Aerospace, Defence and Medical industries to heatstake a variety of applications, using pulsed heat processes to create a dome / rivet by deforming plastic materials.
