Technical Assistance

Gibson Centri Tech Limited can offer a range of services to aid the customer in their successful production of Centrifugal Castings. We will advise from start to finish on the process, because even the smallest parameter change can lead to a successful casting. Our services range from support in the following areas and we can even offer technical assistance using third party equipment. 

Equipment Selection

New or existing? Are you using the correct type of equipment to successfully produce your casting? For example some types of Castings can only be successfully manufactured on a vertical style machine. You also need to ensure that the mould is safely and securely supported to ensure that there is a limited amount of vibration.

Mould pre heating and temperature

 This is a critical area for centrifugal casting productions different alloys and different coatings require temperature adjustments and most importantly you must ensure that the mould is free from moisture. Correct temperature will reduce or eliminate pin holes in casting as well as aiding metal flow.

Housekeeping

Mould cleaning is an area which can give you instant improvements and scrap reduction, but it is sometimes one of the most neglected areas of centrifugal casting production. Moulds internally should be free from carbon deposits, old mould coating and oil as these can all lead to coating flaking off and subsequently scrap casting. Care should also be taken with the pouring bush/horn to ensure that it is free from metal splatter or loose refractory as these can be deposited in the centrifugal casting. 

Mould spraying equipment

Automated spraying machines if set up correctly will accurately and evenly deposit mould coating on the mould surface offering full repeatability. Automated spraying allows customers to reduce machining allowances speed up production, reduce scrap and stuck castings. Hand spraying will always be required for low volume and complex shapes, having the right equipment with correct parameters set is vital in achieving accurate spraying patterns. 

Mould Coating 

Coating selection, there are plenty of different coatings available on the market we manufacture two ourselves Alumina (TriGex) and Silica (300/3) which has been successful with different alloys over many years but we will use your coating selection or if no preference the best coating for your production which we will then optimise for your castings.

Casting Extraction 

Push or pull system, there are many different ways to extract castings a lot depends on the size and quantity of the casting being produced. If a casting fails to extract you need to investigate the cause as it might not be the equipment it could be anyone of the processes leading up to the extraction.

Casting Handling

This area can save a lot of time, a lot will depend on quantity of castings and what further onward processing is required for example a robot could automatically load castings onto a conveyor of an inline shot blasting unit or even as simple as a gravity conveyor. 

Gibson Centri Tech understand the unique environment of the foundry and we design and manufacture equipment accordingly. Every stage of manufacture is under the company’s control and precise dimensional accuracy is assured. Our extensive experience in project management and commissioning ensures that every aspect of your project is coordinated to meet production deadlines and all your necessary performance criteria.

Why Choose Centrifugal Casting

Centrifugal Casting results in a superior casting with improved mechanical properties and purer structure when compared to static casting.

Centrifugal Casting also:

  • Requires no in – gates or feeder heads
  • Comparable to forged castings in terms of mechanical properties and micro structure
  • Substantial savings on capital equipment
  • The Centrifugal Casting process is not limited to a specific type as most metals are castable and    bi-metal castings are possible.

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.
