Co2 Moulding process – Advantages and Application CO2 Molding Introduction: CO2 Casting is a kind of sand casting process. In this process the sand molding mixture is hardened by blowing gas over the mold. This process is favoured by hobby metal casters because a lot of cost cutting can be done. In addition, one can be sure of getting

The packing of the sand is also automated in a process known as flaskless molding. Despite the name of the process, a flask is still used. In conventional sand casting, a new flask is used for each mold. However, flaskless molding uses a single master flask in an automated process of creating sand molds. The flask moves along a conveyor and has sand blown against the
Dampen the sand with water to make it moldable. Step 4 Press the model of the object that you wish to reproduce into the wet sand, dislodging the sand in the process. Pull the model carefully from the sand, straight up to disturb as little of the sand as possible, leaving an imprint of the model behind as a sand mold.

When the situation deals with intricate moulding patterns, for instance patterns with considerable differences in height along with complex contour, heavy sand risers, KW AIRPRESSplus technology has proven itself extremely well on an international scale. A strong air pulse is applied to the sand, leading to a compaction front through the sand to the pattern plate. This kind of
MOULDING SECTION. 53 grade cement of required quality, Sand Metal are to be taken into bins of weigh batcher by means of Loader. As per our Mix design all these in gradients are to be taken into revolving mixer and then graded best quality concrete is prepared by adding water into it.
The raw sand is normally of a higher quality than the typical bank run or natural sands used in fill construction sites. In the casting process, moulding sands are recycled and reused multiple times, small residues of ferrous and nonferrous by products often come from the recycling process.

The sand which is used is cleaned and reactivated by adding of water, binder and special additives. And the sand we get through this is called system sand. System sand is used to fill the whole flask in the mechanical foundries where machine moulding is employed. The mould made with this sand has high strength, permeability and refractoriness.
