Stone Hammer Blow Testing Instrument - China

Work Principles A certain weight of gravel is bounced into the feeder by vibration.

Due to the vacuum formed by the high speed air flow in the lower part of the feeder, the collision medium is sucked into the ejection gun assembly, and then is shot into the test sample by the jet stream.

After the medium hit the test target, the medium falls into the gravel collecting box.

The test machine causes a large number of steel balls or rubble with sharp edges to hit the sample surface in a short time.

The whole experiment is carried out under a controlled temperature.

After the impact is finished, the loose coating is removed with adhesive tape to reveal the residual stone strike marks on the sample, which can be used to judge the performance of the resistance to stone impact by analyzing the damage degree of the sample.

Standards SAE J400, VDA 621427, ISO 20567-1, ASTM D3170, GMW14668-3.4.9, Peugeot/Citroen D241312, Chrysler 463PB-52-01 , Chrysler 463PB-39-01, Mazda MES MN 601C, Toyota, Nissan, Ford BI 157-04, Ford BI 157-05 - The new gravel impact tester is assembled by standard component and equipped with easy handling accessories, achieving gravel impact against all the main standard automotive materials on this one machine.

It is the only instrument in China that adopts the universal adjustment device, and the 0-180 impact angle can be adjusted arbitrarily.

( the so-called mufti-functional instruments produced by other manufacturers is actually equipped with different angel collision boxes ).

The first disadvantage is that customers need constantly change collision boxes with different angles.

It has a lot of trouble to make replacement and the collision boxes of different angles will cover a large area.

The second disadvantage is that the collision boxes are not complete enough with different angles to meet customers need for subsequently adding the required impact angles.
