Cast iron gearbox housings is made by a process called metal casting or by using molds. This casting are durable in nature and sturdy and use in various applications like lip seal, Taconite seal and many more. Fabricated gearbox housings are fabricated in hi-tech machining centers and used in heavy industrial machines like cast iron, steel and so on.
