• Covering and drossing of aluminium melts.
• Modifying aluminium silicon alloys.
• Removing aluminium oxide build up on the furnace walls.
• Recovering aluminium from the dross.
• Melting of turnings, borings and chips.

ALDEGAS range of products are used for degassing and degassing cum grain refining of aluminium and it's alloys.

During the melting of aluminium and it's alloys, the hydrogen gas is picked up by the melt resulting into gas porosity in the cast products. It is necessary to remove this hydrogen gas from the molten metal before the casting operation. ALDEGAS addition removes this picked up hydrogen from the metal.

ALREFINE range of products are used for grain refining of aluminium and it's alloys.

Aluminium and it's Alloys when allowed to cool under normal conditions, form coarse crystalline structure. This coarse grain structure is prone to -

(a) Cracking during metal working
(b) Poor feeding characteristics
(c) Poor surface finish.

Alrefine addition overcomes these problems by producing fine and uniformly distributed grains.

The use of Aluminium Master Alloys for the purpose of modification and grain refinement are becoming common in the aluminium foundry industry.

Ease of addition, cleaner environment, greater control over treatment processes, improved consistency in the casting quality are some of the advantages of using master alloys.

Binders for making cores and moulds by the Carbon Dioxide process.

As cores and moulds are dried by passing carbon dioxide gas, expensive drying ovens and core carriers are not required, which also reduces the floor space. Labour cost is also reduced because cores and moulds are made easy. Gives dimensional accuracy.

Corepowder is a pre-gelatiminized coreal binder used with core sand to give sufficient green strength effectively and economically.

Can be used effectively and economically and gives excellent green strength. Improves collapsibility and imparts better surface finish.

Core jointing compounds for self drying and oven drying cores. Forms a very strange core joint. Different types of corebind are available to suit varying requirements.

Very simple and inexpensive to use and forms a strong permanent joint. Damaged cores can be repaired.

Core oil to give good dry strength and quick drying property to cores.

Dries quicker than the usual linseed oil. Cores and gives good consistent dry strength, Gives good collapsibility and imparts better surface finish.

(A RANGE OF DIE DRESSINGS FOR GRAVITY AND LOW PRESSURE DIE-CASTINGS OF ALUMINIUM AND ZINC BASE ALLOYS.)

Gravity and low-pressure die casting processes are used for producing quality non-ferrous alloy castings. These processes however are particularly complicated in case of light alloys (e.g. Aluminium) due to their greater tendency for gas pick-up, surface oxidation and higher heat dissipation.

Castings will end up with shrinkage, misrun defects unless metal flow and heat losses are controlled well. Refractory die dressings play an important role in the production of sound castings. DIE PAINT range of products caters to all the technological needs of the die casting process.

(A RANGE OF DIE DRESSINGS FOR PRESSURE DIE-CASTINGS OF ALUMINIUM AND ZINC BASE ALLOYS.)

Pressure die casting process is used to produce Aluminium, Zinc castings of exceptional dimensional accuracy and metallurgical soundness.

In this process, the molten metal is injected at a high velocity in to the die with the help of a plunger. Die dressings play a very important role in -

(1) Both physical and chemical protection of the die in addition to lubrication.

(2) Ensuring smooth operation of the plunger.
DIE-PAINT range of product offers suitable products for the same.
