NovaCast shows the way to a greener, more sustainable industry

Over the years the metal casting industry has acquired a reputation as one of the worst in terms of environmental impact, largely due to traditional production practices with high energy usage going in and highly toxic emissions coming out. Add to this the massive energy demands for the extraction and production of raw metals, such  … Read more

The Use of Fluxes in Aluminium Casting

At NovaCast, a large proportion of our castings are produced using Aluminium alloy. The formation of Aluminium Oxide and the presence of non-metallic inclusions, collectively known as dross, is an inherent part of the casting process and one that must be managed to achieve the highest quality castings. For many years, part of the foundryman’s  … Read more

The differences between Lost Foam Casting and Lost Wax Casting

In many respects, the process involved in these two investment casting methods is similar. In both cases, a sacrificial pattern is made. In lost wax casting, this is made from a tooled mould and in lost foam casting, it may be made from a mould or carved from a solid block of foam material. A  … Read more

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  … Read more

NovaCast Heat Treatment

Heat Treatment of Castings

Heat treatment of castings is primarily used to alter the physical, and sometimes chemical, properties of the cast alloy. Many of the mechanical properties of both ferrous and non-ferrous alloys are determined by their microstructure. Heat treatment Is an efficient way of manipulating the crystalline structure of the alloy to modify its mechanical behaviour in  … Read more

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  … Read more

Focus on Metal Surface Treatments

NovaCast routinely uses a wide range of metal surface treatments on its cast products to enhance their mechanical, electrical or aesthetic properties. Surface treatments and finishes are often applied following surface preparation, usually in the form of fettling, linishing or shot blasting, and any final machining. Here, we focus on the surface treatments most commonly  … Read more

Aluminium Bronze in Metal Casting

The use of Aluminium Bronze in Metal Casting is widespread as it is a remarkably versatile alloy, conforming to the requirements of BS1400, and created when Aluminium is added to Copper as the primary alloying element with smaller amounts of Nickel and Iron to boost corrosion-resistance. Various grades of Aluminium Bronze are available with the  … Read more

What is Shell Mould Casting?

At NovaCast, we offer a wide range of casting process options as each have strengths and weaknesses that make them suited to certain applications and alloy choices. Shell Mould Casting is a metal casting process similar to sand casting, in that molten metal is poured into an expendable sand-based mould. However, in Shell Mould Casting,  … Read more
