How cores extend the flexibility of sand casting
Creating cores is an art in itself and follows many of the principles that dictate the production of sand moulds. Without cores, the use of sand casting would be far more limited. In addition to the ability to introduce more complex designs, internal voids and structures, cores can deliver other benefits. Even where internal voids are not needed...
The Difference Between Gravity and Pressure Die Casting
Die casting is one of the most widely used casting processes but what is the difference between Gravity Die Casting and Pressure Die Casting? Both are casting processes used by NovaCast, so we are well placed to explain the differences and discuss the selection criteria. Both forms of Die Casting employ a metal mould into...
Elements of a Sand Casting Running System
The gating system includes all those elements which connect the pouring ladle to the mould. The various elements include: Pouring Basin or cup, Sprue, Sprue Base Well, Runner, Runner Extension, In-gate and Riser. An effective gating system should: Fill the mould cavity completely before the metal starts to solidify Control the speed that metal enters...
The case for Sand Casting
The Sand Casting process has been a key element in manufacturing for thousands of years and still accounts for approximately 70% of all castings. Whether Sand Casting is the best option for the production of a particular component will be dictated by considerations such as the required geometry, performance, alloy choice, production run, tolerance within...
