Golf Ball Deflection Test
A golf ball manufacturer has factories based in both the US and India. The test requires the hardness of different grades of golf ball to be measured, in order to maintain consistency in their manufacturing process and offer the same quality of product from both factories. As far as possible, the manufacturer wished to simulate the fast speed contact of a golf club to the ball, so a speed of 20”/min was selected.
Mecmesin supplied a MultiTest 1-i, capable of testing forces up to 1000N, an S-Beam load cell and two flat compression plates. For reliable result accuracy, the golf ball is placed on top of one compression plate, maximising surface contact. To perform the test, the compression plate is lowered at a speed of 20”/min. Once the plate makes initial contact with the top of the golf ball, a ‘touch‘ is registered. The system begins measurement at zero from this point. The compression plate continues to apply a load up to a maximum force of 200lbf, then pauses for 2 seconds.
