Drying only a defined portion of a small, lightweight component in a specific quantity, time, and quality is a challenge. It took experience and innovative spirit to master this application.
A renowned supplier needed a special drying solution for a new component series. The components in question are small caps of highly complex geometry for use in the automotive industry. The requirement for drying is restricted to the bottom of these caps where three small pins are attached. Three dozens of these items, which may not be depicted for secrecy, are placed in one plastic cartridge each. They are processed as follows. To obtain lasting, perfect quality the pins are insulated, gold plated for optimum electric conductivity, and rinsed. Then, they need to be dried. The enterprise has used Harter rack and barrel driers in factories the world over for more than 25 years. So, obviously, they contacted their established technology partner for energy-saving heat pump based condensation drying. This application requires a continuous drying solution.
