Metal Casting Technologies : March 2006
METAL Casting Technologies March 2006 57 PRODUCTS OMEGA Spartan 220P mixer Omega Foundry Machinery Ltd's design of the Omega mixer has been a process of continuing development since its introduction in 1959. Mixer development has been in parallel with the changes in the chemically bonded sand process and its application in the industry during the last 40 years, from the sodium silicate/CO2 system to the latest self setting processes using a variety of sand, resin and catalyst programmes. These have been installed with control systems based on sand temperature, resin flow and catalyst flow using the latest plc technology. Foundries have appreciated the advantage of the IRIS pattern tagging system (introduced in 1999) where a 'tag' attached to the pattern is able to be recognized by an antenna at the mixer station and then accesses the data stored in the plc control. This data provides a pre-determined type of sand, weight, setting time and compaction table frequency and time so relieving the operator of manual control. The system also provides for the storage and availability of production information and material consumption data, even at computer terminals away from the foundry moulding area. The IRIS system has been successful in small and large foundries with roller track loops or automatic moulding lines with mould sizes up to 2000 x 1500mm.
