The applications and machine requirements for this are as diverse as the products themselves. Our machine range has covered from dispensing shots ranging from 0.02ml to 50Kg +, using filled and unfilled Epoxy, Polyurethane or Silicone, often needing to be stirred, heated, or de-gassed etc. They are being used in simple manual and robotic applications, with single or multiple dispensing heads.
When selecting the correct machine from our range, the process of actually potting the component has to be considered. If you are making the transition from manual to machine application, there are some general guides that can apply to this process.
This programmable stepper/ballscrew driven Iota C is used to dispense a 12gm shot of 4:1 PU at a slow, controlled varying rate over a 30 seconds cycle to prevent air entrapment in the component.
Because of the diversity of processing requirements and shots sizes, sometimes the need for multiple cycles, we offer use both piston and continuous delivery gear pumps for metering. For example, we have used 6 different types of machine for potting transformers. Therefore while there is not a definitive ‘Potting’ machine, we can provide the definitive machine for your specific application requirements, albeit the simple small shot Iota R or a high output rate MasterCaster gear pump machine with degassing and heating.
