The foam molding machine system adopts multiple heating methods, adopts the solid and moving mould balancing valve system, controls the instrument and controls the valve parts to complete the circulation, and further saves the steam of the machine. The unstable factors of product quality caused by unstable steam source are solved and the quality is greatly improved. The steam and cooling water valves adopt imported components. The operation is safe and the performance is stable. One person can operate 2-3 machines in the foam molding machine. The use of an additional device on a rotary table (EPS foam foam cutting machine) is generally used for profiling processing, and also for cutting out rotations, including spheres.
