Full Technical Support

The Gibson Centri Tech Limited Technical team uses the latest techniques to design your centrifugal casting machines.  Our Engineers solve even the toughest design problems quickly and efficiently using the latest techniques. Our Engineers use the latest AutoCAD 2D and Inventor 3D to complete the designs of every customers centrifugal casting machine before any metal is cut. This allows design reviews to be presented in an easy to understand format, allowing a rapid and inexpensive development process. Our customers can then realistically visualise all component parts prior to machine manufacture, giving them a better understanding of each machines capabilities.

Horizontal And Vertical Process

Tags : 

It is Acknowledged that both Horizontal and Vertical Centrifugal Casting can be used with ferrous and non-ferrous materials. The same machines can cast ferrous and non ferrous, the only difference is some process features have to be tailored to suit the alloy such as:

  • Spinning speeds
  • Pouring rate
  • Mould temperature
  • Molten metal temperature
  • Mould coating
  • Water Cooling

Horizontal Centrifugal Casting

Is best applied to castings of greater length than diameter and which have cylindrical bore. This is why you will commonly find tubes between 300mm to 6000mm long. It is possible to create shaped casting horizontally using a shaped mould or sand inserts.

Vertical Casting

This is commonly used for cylindrical shapes where the diameter exceeds the length or height of the casting one, exception to this are steel mill rolls where using a roller guide system, castings with a longer length to the diameter are manufactured this is to allow the manufacture of solid castings.

It can also be used for complex castings shapes such as Ball Valves and Propellers.

Due to the gravitational pull while pouring the material a parabolic effect takes place in the bore, this can be altered by changing the speed for casting.

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.
