Cast Iron vs. Fabricated Steel: The CFM Difference
The one on the left costs 50% less than the one on the right.
What's the Difference?
Cast Iron Can Offer Some Big Benefits To Your Production*
FEWER NUMBER OF PARTS
There are far fewer parts required
to build our cast iron example. That means you can save the cost of inventory,
and precutting all the parts needed to build the fabricated model.
FAR LESS LABOR
Cast body and rotor require much less labor
time, and eliminate the labor-intensive fabrication process.
INCREASED PERCEIVED VALUE
Castings have an inherent
appearance of strength and ruggedness, a value-added feature to sell your
The performance and durability of a cast
iron rotary airlock is equal to or better than one made of fabricated steel.
LONG RUN ECONOMY
Castings can have a big advantage over
fabrication when quantities are sufficient.
comparisons do not include the cost of material cutting, storage, and inventory
for fabrication, or pattern costs for castings. They also assume that bearings,
seals, machining, and assembly would be the same on cast and fabricated
