3: Cooling system

Fountain or spiral cooling structure is used in the core.

Spiral waterway is used to milled outside the cavity,improve cycle efficiency and reduce cleaning times.

Neck drilled cross cooling channel.

Each plate is individually designed with a circulation cooling channel.

Optimized cooling layout is used to ensures fast and efficient heat exchange between steel and water and support fast cycle times to save energy costs.
