Industrial Mould Hardness Tester

Manufactured in accordance with AFS specifications, our Mould Hardness Tester is used to determine the surface hardness of green sand mold. The Hardness test can be performed within seconds; the user simply presses the tester against the mold surface and notes the reading on the dial. Excessive pressure will not alter the reading and it operates in any position.Details:A 1/2 in. (12.7 mm) radius ball contact point is loaded with a spring pressure of 980 g. The softer the mold surface, the greater the penetration into the mold.A mold offering no resistance to the contact point would have a zero reading and one having hardness capable of preventing penetration would read 100.A maximum reading stop holds the reading when testing in blind portions of the mold
