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 is used to measure the surface hardness of the sand mould/core of the wet mold and provide technical parameters for the formulation of the molding process.
The surface hardness of sand mold is divided into three types: A, B and C, The common model is type B, among them:
Type A: Suitable for the surface hardness test of fine sand mold/core in manual or mechanical low and medium pressure molding.
Type B: Suitable for the surface hardness test of fine and coarse sand mold/core in manual or mechanical low and medium pressure molding.
Type C: Suitable for the surface hardness test of sand mold in high pressure molding.
The unit of type B hardness tester for sand mold surface is (g/mm2), but it is customary to use hardness H(A/B/C) instead of unit. Because their values are related and consistent, the corresponding hardness value is also large when the unit value is large (g/mm2),
Low voltage indicator.
Digital display gives exact reading with no guessing or errors.
Can communicate with PC for recording, printing and analysing by the optional software and cable for RS232C interface.
Automatic power off to conserve power.
