The gas pressure of molding sand prepared by cold hardening technology is a common cause of casting defects. The control of gas pressure allows you to choose the optimal recipe for no bake process identify the cause of the reject and, ultimately, reduce its percentage.

Advantages:

• Automatic operation

• Generation of result graphs

• High-precision temperature, pressure, and weight sensors

• Aesthetic design

• Compact dimensions

  Design and Operating Principle:

  The device consists of a housing with a control system, touchscreen display, pressure, weight, and temperature sensors, and a heating furnace capable of reaching temperatures up to 1000 °C.

  Gas Evolution Testing:

  The furnace is heated to the required temperature.
  A test tube containing the sample with a fitted gas outlet tube is placed inside.
  The device measures the gas pressure released during sample heating and generates a graph showing the pressure variation over time.

  Hardenability and Moisture Testing:

  The sample placed into the device is weighed and heated to determine mass loss.
