Mold and hot runner controller located on the machine platen

An injection molding machine comprising:

• an injection mold mounted to a machine platen, said injection mold having a mold hot-half and a mold cold-half;
• at least one controllable device coupled to said injection mold for varying a processing condition of said injection mold, the processing condition including at least one of temperature, pressure and valve pin position;
• at least one sensor coupled to said injection mold that reports a value of the processing condition;
• and
• a control module, mounted on said machine platen separately from the injection mold so that the injection mold can be removed from the machine platen without removing the control module from the machine platen, said control module being in communication with said at least one sensor and said at least one controllable device, said control module for collecting an output from said at least one sensor, processing said sensor output, and providing a control signal to said at least one controllable device.
