Carousel Range of Centrifugal Casting Machines

Tags : 

One of our high profile Horizontal Centrifugal Casting Machines is the Carousel (Multi-head) Machine. The Carousel Machine range is designed and manufactured to meet the production requirements of medium and large OEM producers of cylinder liners. These machines can produce single liners or multiple lengths depending on size and type. Profiled diesel liners are usually produced in single pieces. Smaller automotive low profile wet or “cast in” block, these liners can be cast in lengths of four depending on the size. The Carousel Centrifugal Casting Machine offer a highly versatile alternative to conventional tube type machines.

The machines are fully automated and can employ either wet or dry coating methods. One of the key elements of the carousel machine is the consistent production the critical points are monitored and controlled throughout the production process. These include pouring temperature and die temperature. The latest control and instrumentation technology are incorporated into the equipment.

Production rates are dependent on wall thickness of the casting. Typically, a six head unit can consistently cycle at 45 seconds producing four cylinder liners per casting, giving an hourly production rate of 320 liners.

Several versions of this centrifugal casting machine are available to suit the production, budgetary requirements and size or type of castings being produced. Six, eight, ten or twelve head models are available with various options, subject to the customers requirements. The reliability of these machines has been proven in the field. In the last five years the company has had repeatable orders from customers in India and the USA, who have purchased various versions of this machine range for their facilities.

This simple to operate but robust design provides greater reliability without undue sophistication.

New to the Centrifugal Casting Process?

New to the centrifugal casting process? Do you have any concerns with regards to how this process can benefit your organisation? Our technical team are experts in the design and manufacture of centrifugal casting machines. Our technical team are always on hand to provide support and guidance.

Below are a few examples of frequently asked questions which we receive:

Should I use a horizontal or vertical 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.

What information do you need to quote a suitable centrifugal casting machine?

We will send you a basic questionnaire which will detail all required fields, but principally the information we require is: I/D, O/D, Length, material and quantity of the castings which you wish to produce.

“We have no experience in centrifugal casting and are worried about our ability to manufacture a successful product”

Gibson Centri Tech Limited can help you with every stage of the process, from guiding you with the selection of your equipment, we can also offer layout drawings of your foundry as well as installing the equipment and providing “Know how” training.

“What are the latest developments in centrifugal casting machinery? “

Gibson Centri Tech Limited believe in continual improvement in our equipment. While the designs can trace their roots back thirty or forty years they have been endlessly improved to meet modern safety standards while embracing the latest technology. The level of  automation has increased and where appropriate incorporating servo drives and robotics.

Gibson Centri Tech Limited – Technical Assistance

Gibson Centri Tech Limited can off 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 part 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.

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 production as 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 castings as well as aiding metal flow.


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 castings. 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 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 in line shot blasting unit or even as simple as a gravity conveyor
