Die Casting is a process where molten metals like aluminium, zinc or magnesium are forced with high pressure into a die cavity. During this process, large amounts of oil mist and oil smoke consisting of sticky particles is formed from the release agent and the piston cooling oil.
The first challenge is to capture the mist/smoke-filled cloud that pours out of the die casting machine. A properly designed hood and a capable filter solution are the main requirements for creating a safe working environment.
One source of oil smoke is the lubrication that is sprayed into the mould cavity. It is often called a release agent and contains various mineral oils, graphite, petroleum and natural waxes etc. Another source of oil smoke is the injection of the molten metal which takes place through the shot sleeve (piston lubrication).
Together these sources create a task too tough for most filter units to handle. It is not unusual for a medium size die casting machine to release more than 1000 kg of sticky, dirty particles into the air every year.
Filtermist's vast experience in designing hoods that capture the air effectively can also minimise the size of the filter unit needed. If heat is needed elsewhere in your facility, you can use the extracted air - saving you money on unnecessary heating bills.
