The casting process

Moulding Techniques

Moulds can be produced by Sprayed Metal, Machine Cut, Resin or Plastic.
We also offer the low cost rubber moulding process that gives rewarding economic return on smaller runs, as so often on small batch requirements, the moulding costs can result in a product being un-economical to produce.
Where necessary we can accommodate a customers Die/Mould so long as it is suitable to our process.

The wax making process

The wax making process

The manufacture of the wax pattern is undertaken using high or low injection, depending on the type of moulding application.
As with the dies, we are able to facilitate a customers ready made waxes.
We are prepared to produce 1 or 1001, it is the customers choice, we are more than aware of the demands from some companies as regards impractical quantities.

Wax assembly

Wax assembly

The individual waxes are assembled onto a runner system until the mould is seen as complete.

Dipping the moulds

The wax clusters (Moulds) are carefully emmersed into various slurry tanks, containing slurries of varying viscocities. They are then coated in a granular medium.
The applications are repeated until the level of cover is achieved, both for strength and practicality.

Moulds drying

Moulds drying

The moulds are then dried within a carefully monitored enviroment.
This is critical to the success and quality of the eventual finished product.

'Losing' the wax

'Losing' the wax

This is the 'Lost' in the lost wax process.
The now cured moulds are placed within a furnace or autoclave and the wax is removed by means of direct heat or steamed enviroment.

Preparation - pre firing

Preparation - pre firing

Moulds are ready to be fired using the 'drop down' furnace, they will be fired at tempuratures up to 1100 degrees in order to prepare the mould cavities for the pouring process.

Moulds fired

Moulds fired

Once 'de waxed' the moulds are very vulnerable to damage and are then 'fired' to higher temperatures, gaining far greater strength.

Different applications for varying mould types

Different applications for varying mould types

There are different types of furnace, depending on the quantity of material to be poured; also the type of material, ie: brass or steel as two examples.

One will 'roll over', another will Hydraulically 'tilt' and the last option is the pneumatic 'drop down'. All of which are powered by an induction generator.

Metal melting

Metal melting

The metal is fed into the crucible in bar form and will melt in appproximately 11 - 15 minutes, depending on the mould capacity.

Pouring of the mould

Pouring of the mould

In this example the steel is poured to the mould at temperatures in excess of 1600 c.
The mould is clamped to the furnace roll over and inverted over so as to allow the gravity fill of the metal to mould.

finally.....

finally.....

The mould is removed from the furnace and taken to cool in a controlled atmosphere.
One sufficiently cool, the ceramic is knocked away to reveal the castings.
These are then cut off from the mould runner system, followed by a fine grit bead blasting to remove the ceramic from the casting surface.
