The Sand Mould Surface Hardness Tester is a specialized instrument designed to accurately measure the surface hardness of sand moulds or cores, particularly those in a wet state. This device plays a crucial role in the foundry industry by providing essential technical parameters that are vital for the formulation and optimization of the molding process. By assessing the hardness of the sand mould or core, this tester helps in ensuring the quality and integrity of the casting, thereby facilitating the production of high-quality metal components with the desired properties and dimensions.
The Sand Mould Surface Hardness Tester measure the surface hardness of the sand mold and core of the wet mold, then provide technical parameters for the formulation of the molding process.
The surface hardness of sand mold is divided into 3 types: A, B and C, The common model is type B.
Type A: Suit for the surface hardness testing of fine sand mold/core in manual or mechanical low and medium pressure molding.
Type B: Suit for the surface hardness testing of fine and coarse sand mold/core in manual or mechanical low and medium pressure molding.
Type C: Suit for the surface hardness test of sand mold in high pressure molding.
The unit of type B hardness tester is (g/mm2), however, it is customary to use hardness H(A/B/C) instead of unit. Because their values are related and consistent, the related hardness value is also large while the unit value is large (g/mm2),
Low battery indicator.
Digital display is directly to see, without guessing or errors.
Communicate with PC for storage, print and analysis by the optional software and cable for RS232C interface.
Automatic power off.
