Enter the digital calibration system, built-in common thermocouple and RTD nonlinear correction table, sand box manufacturers, measurement accuracy and stability. With position adjustment and AI regulation, Jinan flask, 0.2 precision, multi-alarm mode. The device has a timing function. Heating equipment made of stainless steel finned heating pipe. Dust cycle the entire device, vibration cycle can be adjusted, and with a total test of the timer. Priority using sand casting According to statistics, China or internationally, sand box Supply, in all casting production in the 60 to 70% sand casting is produced, and in which about 70% is clay sand production.

So like a car engine cylinder block, cylinder head, crankshaft, etc. are used green sand casting process of production. When the wet type can not meet the requirements to consider the use of clay sand is dry sand, dry sand or other sand. Green sand casting casting weight from a few kilograms up to several tens of kilograms, while dry clay can produce castings weighing dozens of tons.
