Sand Casting
Sand casting offers the simplest medium for production of non ferrous castings, by pouring molten zinc, aluminium or copper into a sand mould.
This process is chosen for the production of small numbers of castings, for complex shape castings requiring intricate cores, or for large castings.
Advantages include:
Low cost tooling
Largest casting sizes achievable
Very low gas porosity
General versatility
Limitations include low casting rate, 3-5mm minimum wall thickness, poor linear tolerance (e.g. 4mm/m), rough surface finish (6.5-12.5mm), and a coarser grain size than gravity die castings.
The huge advantage of sand casting is the production of complex shapes however the surface finish and tolerances of the finished casting are poor relative to die castings. Production times can also be a lot longer than other casting processes such as gravity die casting and high pressure die casting.

31st May 2018
Around 6 months ago, we took a hard look at how we use the data we have available to us at MRT Castings. We looked at everything from data being used by machines, data being created by machines all the way through to where data is being left on the cutting room floor and where data can potentially be corrupted or lost through human error.
