Centrifugal Casting

Centrifugal casting is a fast, efficient and low-cost method of producing superior quality hollow-bar for machining into your components. It can be supplied in a wide range of standard or client-specific sizes and alloys.

As its name implies, this method of casting uses centrifugal force to produce items of cylindrical form which have a dense fine-grained metal structure and improved physical properties.

Molten metal is poured into a rapidly rotating steel die and is forced against the sides of the mould by the tremendous pressure exerted by the centrifugal action. The force assists in forming a consistent, high-integrity, superior-strength material.

The centrifugal force also displaces any dissolved gases and suspended non-metallics ensuring that they are segregated to the inside diameter for easy removal by machining.

It is an economical alternative from which components requiring high temperature, corrosion and wear resistance with a homogeneous structure and constant machining characteristics can be machined.

Very few gravity-cast foundry products can compete with the high quality fine-grained components produced using our precision centrifugal casting techniques.

Applications

Hycast Metal's centrifugal cast hollow bars are available in a broad range of standard and non-standard sizes and all types of air melted alloys. They provide significant material and machining cost savings when compared with solid bars.

Our standard bars are produced in lengths of up to 6OOmm with outside diameters ranging from 95mm to 530mm. The hollow bars can be cast with varying wall thicknesses to your specifications. They are an ideal source of machining stock.

We also produce components with hexagonal, square or tapered outer diameters, tapered bore, truncated cone sections, combinations of different diameters and shaped outer surfaces. In fact, if you provide us with a drawing, we can create a part to meet your exact specifications.

Some of the many types of components produced from our material include wear rings, seals, bushes and bearings, rollers, gear blanks, pump sleeves, general and pipe flanges, furnace parts, cylindrical or ring type engineering components and forged stock.

These are supplied to companies involved in a diverse range of industries including light and heavy engineering, manufacturing, food processing, minerals extraction, materials handling, pump and valve production and general engineering.

Alloys

Our products are cast in all grades of heat, corrosion and wear-resistant alloys. Clients can choose from a range of steels and stainless steels (including Ferritic, Martensitic, Austenitic and Duplex grades) as well as nickel alloys, cobalt alloys, brass, bronze and other alloys to suit most purposes. Your own special alloys may be also made up for specific applications and certified in our NATA registered metals analysis laboratory. The most commonly cast materials are listed on the chart to the right.

Finish

We can supply castings in an unmachined condition or we can proof-machine or finish-machine them according to your requirements. Products can also be heat treated to individual specifications. Most commonly Cast Metals
