SYS-B Sand Mould Surface Hardness Tester

Product Description

SYS-B Sand Mould Surface Hardness Tester

Features:

It is suitable for measuring the surface hardness of various green sands.

It is used to determine the wet sand mould (core) surface hardness, for playing molding process to provide technical parameters. According to the size of the spring force and the stroke is the principle of linear relationship, the size of its stroke through a set of gear, the transmission of the rack by the surface pointer. The hardness of the surface of the sand B Type of unit is (g/mm2), but not in the habit

of units but with the hardness to say. Because their values are related and consistent, both large (g/mm2), the corresponding hardness value is also large.

Specifications:

1. Compression stroke: 2.50mm

2. Maximum load: 980g

3. Pressure load: 50g

4. Head shape and size: Ball R12.70

5. Accuracy: When the pointer is at any value, the pressure of the pressure head is allowed to be 5%. When the pointer is returned to the 0 position, the tolerance is 1 degrees.

6. Outline dimension: 90 * 55 * 28mm

7. Scale: 0-100
8. Standard Delivery

Operation:

Adjust the 0 position, when the pointer is not in the 0 position, turn the adjusting ring, so that the pointer to the 0 bit. - use the hardness is pressed on the tested sand plane (hardness of the axis perpendicular to the surface of the sand), the hardness meter gauge plane and the measured sand plane close contact, the pointer stopped at a certain value, press the locking pin locking be locking, read out the determined value, then loosen the lock locking the pointer back to zero. In each test, 5 to 3 times, and then to calculate the average number, both the hardness value of the site.
