The molds used to hold cast iron are made from green or chemically bonded sand. The choice of a casting method is based on the size and weight of the castings as well as the size of the run.
When production runs exceed a certain quantity and desired castings fit in a 20’’x24’’ mold and weigh less than 100 lbs, automatic molding is the favoured method.
Our innovative DISA MATCH 20/24 machine allows us to create reliable and efficient molds that are crucial to the quality of our final product.
This machine yields the same quality as a vertical molding line, but functions on a horizontal basis, which significantly reduces matrix production costs. Only one pattern plate is needed with this technology, whereas vertical molding lines require two facing pattern plates.

As the name suggests, this molding method is characterized by both machine and human intervention, the latter being more substantial compared to automatic molding. This method is indicated for mid-sized castings weighing 50-400 lbs.
This manual method is becoming increasingly rare in modern foundry. It is used for small orders or when the size or weight of a casting is not suitable for machine molding. This entirely manual method consists in packing greensand with a pneumatic tool to create a mold.
