Cast Iron Restoration

Three Key Steps To Determine If You Can Repair A Cast Iron Break Or Crack

It is not easy to repair cast iron due to the brittleness of the metal. Compared to steel and wrought iron, cast iron is one of the most difficult metals to repair.

There are three stages to assess whether you can repair a cast iron break or crack:

1) Can the break or crack be repaired?

Generally speaking, a small break or crack can be repaired. Larger breaks and cracks may need specialist preparation, metal filling or extra work to complete a repair. Before any work is undertaken on the part, it is best to take a digital photograph of the break or crack and send it to a specialist cast iron repair company for analysis.

They will be able to advise on the type of cast iron repair to be undertaken and the fees involved.

2) Is the cast iron break or crack accessible?

If the cast iron part can be removed then this makes the repair process much easier. Removing the cast iron part should be done carefully and in a way that retains all other fixtures and fittings (brackets, nuts, bolts etc).

If the part cannot be removed, then there needs to be consideration into how much space surrounds the part as to whether an in situ repair could be undertaken. In situ repairs are possible on larger machines, but can be very difficult to perform on smaller machines.

3) Is it economical to repair the part?

Budget is always an issue when deciding whether a cast iron part can be repaired. If the part is easy to remove and readily available as a new part, it could be cheaper to fit a new part.

Older parts from car engines, generators, pumps etc may not be available as new parts and will require a repair.

Cast iron is used in a wide variety of parts including cast iron cylinder heads, engine blocks, exhaust manifolds, turbocharger casings, valve bodies, pump housings, gearboxes, electric motors, flanges etc.
