    Capacity : 250 kgs.

2. Dumble cutting :
    Press with request dies

3. Ageing testing Oven

4. Muffle furnace, for checking ash contents

5. Specific Gravity balance tester

6. Elongation testing machine

7. Hardness tester
    Shore 'A' hardness tester to verify the hardness of each batch

8. Dimension testing by 
    Electronic vernier calipers, Dial Gauges etc.
