Process Control To Deliver High-Quality ...

As the iron travels down the molding line, the temperature gradually decreases from about 1,200 to 900 degrees Fahrenheit. Temperature at this stage varies based on the size of the casting as well as the molding rate. At the end of the mold line, castings enter a shakeout process where the molds are shaken off and the sand is recycled for reuse.

Casting Process

Adequate process control is important, i.e. metering of molten metal, pressures, solidification times, tooling temperatures, etc. to avoid porosity. Defects can be minimised through correct die design, e.g. multiple gate system, by increasing die temperature, or by decreasing delay time before die closure.
