Why Choose Centrifugal Casting?

Tags : 

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.

Centrifugal force brings about an even distribution of the metal and forces gases and other impurities out of the critical section of each casting, resulting in consistent, high quality output with superior physical properties.

By refining the operating techniques and upgrading it’s programmable machines with a number of innovative features, Gibson Centri Tech Limited has improved still further the efficiency and productivity of a well established process.

 

 

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 hallow cylinder. It is then easy to remove these impurities.

Flexibility

The centrifugal process allows economical production of a wide range of sizes, shapes and quantities.

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

“We are trying to improve our production range of centrifugal rolls. Please advise the best centrifugal casting machine and procedure we would need to approach to achieve our desired results”

Gibson Centri Tech Limited would first propose to initially offer a preliminary technical study covering the following points:

  1. Review the selected cast products required to establish their suitability for centrifugal casting and equipment type.
  2. To establish suitable equipment and moulds to produce the required casting.

 

For more information on our preliminary technical studies, email our sales team: sales@gibsoncentritech.co.uk

“We are producing centrifugal castings for cylinder liners. Please advise on which mould coating would be most suitable for our production needs”

Gibson Centri Tech Limited produce a range of silica and alumina coating. However, if we feel our coating is not the best product for you we will recommend an alternative supplier. Over the years silica coating has been a popular product for use in the manufacture of cylinder liners and is still used extensively. However, nowadays with modern health and safety requirements the customer would need to check local regulations before using this product and ensure suitable dust extraction and PPE is used.

“We are considering having an annual service on our machine, is this a service that Gibson Centri Tech Limited can offer?”

We do offer annual servicing on all of our centrifugal casting machines. We believe that it is beneficial  to ensure that your foundry equipment is in the best possible condition. With annual machine servicing planned maintenance will help to reduce machine downtime and will increase the life of the equipment.

Do you need a different machine for ferrous and non-ferrous centrifugal castings?

The Short answer is no, the machine does not mind which material is being poured. There can be difference in the mould design depending on the liquidus temperature and wall thickness of the casting being produced.

Should I use a horizontal or vetrical casting machine to manufacture my product?

The general rule is if the diameter exceeds the length vertical centrifugal castings are more suitable. However, there are exceptions, solid castings can only be made vertically, some alloys are more suitable for vertical centrifugal casting and sometimes people just prefer either the horizontal or vertical method.
