Mould Coating for Centrifugal Casting

Centrifugal Casting is the spraying of the inside of the mould with a coating. This performs several functions including protecting the mould, aiding extraction and providing even chilling of the castings. For these reasons suitable mould coating material and spray equipment should be used. 

Gibson Centri Tech Limited produces two types of mould coatings designed for centrifugal casting applications to assist traction on the coated surface, allowing an even flow of metal during the casting process, controlling cooling rates and enabling ease of extraction of the casting.

GCT 300/3 Silica Based mould coating –  supplied in 4 x 300kg Drums

This coating is suitable for:

Most steel alloys

Cast iron

All non ferrous metals

TriGex A Alumina based mould coating – supplied in 5 x 40KG Drums or 250Kg Drums 

This coating is suitable for:

Steel Alloys

All non ferrous metals

All ferrous metals

Gibson Centri Tech Limited – Spray Equipment

One of the vital areas to consider when centrifugal casting is the spraying of the inside of the mould with a coating. This performs several functions including protecting your mould, aiding extraction and providing even chilling of your casting. For these reasons a suitable mould coating material and spray equipment should be used. 

10 litre or 40 litre feed containers with hand spray gun supplied for up to 2.0 metre mould length. 

Gibson can also supply mould coating materials both alumina and silica based. 

The most cost effective method of applying coating is hand spraying and in many cases this is acceptable. Depending on the finish and consistency you wish to achieve from your casting, an automated spraying system may be required. For applications like cylinder liners and thin wall castings, automatic spraying would be used to give consistent and repeatable levels of coating. this can also help to reduce machining allowances. 

For more information on spray equipment, contact Tracey Anne in our Sales Department: sales@gibsoncentritech.co.uk

SHPP Range of Centrifugal Casting Machines

The SHHP machines, originally designed for pipe production, are also ideal for the manufacture of cylinder liners for use with internal combustion engines. The machines are available in a range of sizes to produce both pipes and most types of cylinder liners wither with profile or plain Cylindrical castings. They have the advantage of flexibility, relatively low cost, simplicity and ease of maintenance. 

The SHHP models evolved from the Gyra Caster range of Horizontal Centrifugal Casting Machines. These models were initially developed for the automatic production of rainwater and soil pipes. They soon became popular with Cylinder Liner producers who wished to produce plain liners in tube form, up to 2000mm long. Dedicated variants specifically for Cylinder Liner production have been developed. One of the benefits has been consistent production with the variables controlled with mould temperature monitoring and multi manifold water cooling. The machine is controlled from a central PLC system, which can include the options of process data collection. 

Alternatively the less sophisticated Gyra  Caster ‘R’ series is available with lower levels of automation applications for these models including sleeve, rolls, alloy tubes and pipes. The ‘A’ series Gyra Caster is a versatile fully adjustable machine with models available exceeding 25 tonne Capacity.

Other Advantages of Centrifugal Casting

The practice of Centrifugal casting, involves using a centrifugal force, the force when a body is subject to a high velocity spinning action to exert pressure onto molten metal as it is poured into a die, this method has a number of advantages over traditional static die-casting methods.

Other Advantages of Centrifugal Casting are: 

Reduction of Equipment Cost

  • Centrifugal Casting offers a substantial saving on capital equipment when compared to forged products.

 

Reduction of Manufacturing Costs

  • The uniformity resulting from the centrifugal casting process means that machining time and material waste are significantly reduced. Blowholes, sand residue, hard spots, cavities and porosity are virtually eliminated. 

 

Extensive Life

  • Due to the finer grain and denser structure of parts with Centrifugal there is an increased usage life, greater endurance and impact without fracturing.

 

Fewer Castoffs

  • The force used to distribute the molten metal as it is poured is so strong it displaces the lighter oxides and impurities to the centre of the hollow cylinder. It is then easy to remove these impurities. 

 

Flexibility

  • The Centrifugal process allows economical production of a wide range of sizes, shapes and qualities.

In short centrifugal casting results in longer life, reduced rejects, reduction of manufacturing costs and production flexibility.
