Episode 4: Automated pouring in casting processes

There is a problem in the pouring accurately of special car number plates mounted to the mould when it is based on visual confirmation as the influence of dust, high temperatures, vibrations or other conditions particular to the production site make work very difficult.

In foundry conditions the number plate is invariably difficult to see because of dust and therefore increases the likelihood of human error. In addition the versatility to switch between different types of operation and high work efficiency, essential for responding to a variety of needs in such an environment are difficult to attain.

The solution is simple, by storing information about the mould number and pouring hole position in Data Carriers (ID Tags) directly mounted to the moulds allows data to be read from the tags. The carriers on the moulds are fitted with an antenna mounted to the pouring machinery can then perform pouring work automatically based on the real time information.

There are three benefits of this type of control, first the mould number reading errors are prevented and consequently human error is eliminated leading to significant reductions in production losses. Next the mould numbers written in the data carriers are read automatically and so the time required to switch between different types of operation will be drastically reduced, again reducing costs. Thirdly the reading 'pouring hole position' information allows complete automation of pouring work. This clearly enables greater efficiency in high-diversity, low-volume production.

RFID tags are ideally suited to this type of application; their stable communication ability is possible even if the data carriers become dirty. The stability of communication is also possible in high noise FA environments because of their resistance to interference.
Furthermore the Data Carrier can withstand temperatures of up to 150°C (302°F), although the mould however, can reach temperatures of up to 1,000°C (1,832°F) and so consideration of the Data Carrier's mounting position is required.
