Automotive Grid Casting: Model 40/40C | Model 60/60C | Model 220/220C

WIRTZ MODEL 40/40C MECHANICALLY OPERATED GRAVITY GRID CASTING MACHINE

The Wirtz Model 40/40C are high speed gravity grid casters designed with state of the art technical enhancements. Efficient casting is provided by electric mold heat, greatly improved temperature controls and our non-recirculating lead delivery system (LDS).

Electric Mold Heat is applied to both the moveable and stationary halves of the mold by two cartridge heaters. Automatic Indicating Temperature controllers, instead of indicators alone, monitor the temperature settings of the mold, ladle and feedline. Any fluctuation in these temperatures are automatically corrected. An indicating read-out is used in the mold gate area. The lead delivery system (LDS) has been drastically improved because the LDS does away with the return lead trough. This system flows from the lead furnace to a dispensing valve where an adjustable amount of lead is allowed to enter the ladle after each pour. As opposed to lead feed systems with a continuous, recirculating flow this method serves to minimize agitation and substantially reduces drossing in the furnace.

Model 40 is used to cast lead antimonial alloys while the Model 40C includes temperature controls and a cooling system designed specifically to handle lead alloys with high solidification temperatures such as calcium as well as with lead antimonial alloys.
