Wirtz Special Duty Gravity Casting Machine – Model 220C

Wirtz Special Duty Gravity Casting Machine – Model 220C

Wirtz Model 220/220C Hydraulically Operated Gravity Grid Casting Machines

The Wirtz Model 220/220C is a high speed gravity grid casters designed for 24 hour / 7 day a week continuous operation. Its heavy duty construction allow high speed continuous operation.

Both the mold and trim die are hydraulically operated to eliminate air and mechanical problems. This hydraulic feature also allows planish or thickness sizing of the grid to eliminate oversize tolerances. The internal scrap conveyor is constructed of steel and is chain driven to eliminate maintenance problems. This conveyor extends under the stacker to automatically return any grids discarded during the stacking operation to the lead pot for remelt.

The state of the art controls and technical enhancements allow the lead system and the mold operation to correct mold temperatures and control warpage even at high casting speeds. For the battery manufacturer, this means longer cork life, fasting casting speeds, and lower scrap rates.
