Foundry
Foundry
Foundry is one of the oldest industries known to mankind. It involves melting the metals and pouring them into sand molds. The sand mould is then broken, and the parts retrieved are known as the casting. These castings are then cut and machined to form a finished part. The parts that cannot be generally fabricated or forged, or just machined, are cast. When the mould is made, there are paths created to pour the metal to form one large or multiple castings; these are called “Runners”. The molten metal first fills up the desired shape, and the excess material rises over the parts, which is called “Riser”. The Runner & Riser are primarily excess material that is to be removed by a cutting operation, like sawing, gouging, or cutting using plasma.
Our Placut air-cooled and water-cooled Plasma series forms the essential solution to the foundry industry. The gouging function comes in handy when there are large diameter runners or rises to be first gouged to reduce the diameter & then they are easily cut. In case of normal investment casting, there are tens & hundreds of castings which are made in the moulds simultaneously. Initially, they used to be gouged using welding electrodes or carbon arc gouging. It had a limitation of frequent stoppages and changes of the electrodes. To overcome the problem, our arc is generated at the press of a button and available for a very long duration, which in turn helps in many such casting excesses to be cut.
Typical Applications
- Cutting of investment casting runner & riser.
- Cutting of the large-sized casting excess part.
- Gouging out large diameter casting excess metal.
- Gouging out excess parts, casting defects.
