Abstract:
1. A method for forming, molding, tipping and/or welding plastic tubing in a mold, said method comprising the steps of: a) generating an RF signal with an RF generator; b) forming, molding, tipping and/or welding the plastic tubing in the mold disposed in each mold assembly of a plurality of mold assemblies mounted on respective platforms; c) providing a control signal from a mold memory disposed in the mold assembly to the RF generator, which control signal is reflective of the parameters of the respective mold and the forming, molding, tipping and/or welding to be performed on the plastic tubing to control operation of the RF generator and provide RF energy to inductively heat the mold and the plastic tubing therein; d) including a computer/controller and the step of providing the control signals from each mold memory to the computer/controller for controlling operation of the RF generator; and serially controlling the operation of each mold assembly, its associated fixtures and the inductive heating of the respective mold through a multiplexer receiving mold dependent signals from the RF generator and the computer/controller.
