Proto-Form Machine. Thermo forming plastics

An updated picture of the completed woodwork and the start of the electrical. Machine will plug into a 50AMP range block. The 2 zones of heating will be controlled by Solid State Relays (SSR) which are visible at the top either side of the breaker panel. They are mounted on large heat sinks as they dissipate a goo amount of heat dependent on load. These are 40A SSR and should be well up to the task of switching the heater elements. The use of SSR means I only need low amperage switches on the control panel to send a DC voltage to the SSR to control the ON/OFF stae of each heat zone.I have yet to select a powersuplly for this but likely either 12 or 24Vdc depending on what I have in my parts stash!
