The power of green sand for producing steel castings

Many types of steel castings have been produced successfully in green sand for many years. They use a variety of different steel alloys, ranging from plain cast steel to highly wear-resistant alloys.

Today, more and more steel foundries are considering automated green sand moulding to increase their production efficiency, flexibility and quality.

Flexible and high quality yet affordable, DISA MATCH matchplate lines are very popular with ambitious foundries producing short and medium series. Depending on the casting geometry and production volumes, both horizontal and vertical green sand moulding lines may be suitable.

Whether you want 100 or fewer moulds per hour or maximum DISAMATIC speeds, DISA has the right equipment for your foundry.

Advantages of using green sand for steel castings

Efficient, flexible solutions from well under 100 right up to 555 moulds per hour
Unbeatable mould quality
Fast, easy pattern changes takes less than two minutes, perfect for short runs
Constant sand/metal ratio due to flaskless moulding
Robust and simple equipment designs use the minimum of moving parts for less maintenance and unbeatable uptime
Simple and proven core setting gives efficient, low cost, short-run production of hollow parts
Extensive automation means only a very small workforce is needed
Low cost patterns with many material options depending on application
Pattern lifetime can be very high. Steel patterns can produce hundreds of thousands of moulds
Normally only one set of pattern plates is needed, even for high production volumes
Long service life and single set of production patterns delivers low pattern maintenance
Short lead times from CAD file to the first prototype and to start of series production
Changes to runners and feeders are easy, fast and cheap to make

Many foundries would profit from switching their steel castings to a green sand process. Not all steel castings can be feasibly produced in green sand but the advantages above mean that many already are.
