T201 Stone hammer blow testing instrument Operation Steps

T201 Stone hammer blow testing instrument is a test equipment independently developed and produced by our company Shanghai Qianshi Precision Electromechanical Technology Co., Ltd. It has high-cost performance and complete after-sales service. It is mainly applicable to the test methods of German, Japanese, and American automobile manufacturers, and can accurately reproduce the damage phenomenon caused by flying gravel.

Scope of application:

It is used to accurately reproduce the damage phenomenon caused by flying gravel, suitable for the cohesive failure test of the outer coating, the adhesion failure test between different layers in the coating system, the brittle thickness of hard glass materials, the thickness of the optimal coating film for anti-peeling, the anti-peeling, anti-collision and anti-wear tests of plastics and glass and other related tests.

Applicable standards:

GMW1407, JISM0141, TL211-6, GME60268, ASTMD3170, SAE J400, FORD, Chrysler463PB-39-01, GMW14668-3.4.9, Chrysler463PB-52-01, GM9119P/9508P/9619P, MazdaMESMN601C, Nissan, Volkswagen, Toyota, ISO20567-1

Operation steps:

First: prepare the accessories and test samples;

Open the door of the impact test box;

Put the test sample into the fixture and fix it;

Tilt the fixture above the scale and lock it;

Lock the door of the impact box;

Put the prepared gravel in a Stainless steel funnel;

Turn on the power switch and enter the LCD screen operation interface;

Set the impact time and impact pressure;

Open the funnel valve;

The high-speed airflow at the bottom of the feeder forms a vacuum, and the gravel is sucked into the gun assembly;

The jet airflow is shot at the test sample in the box;

After hitting the test target, the gravel falls into the gravel collection box;

When the test is over, open the test box door;

Take out the sample, analyze the degree of damage to the sample, and judge the quality of its anti-stone impact performance;

After the test, turn off the instrument;

After the instrument test is over, take out the sample, and judge the quality of its anti-stone impact performance by analyzing the degree of damage to the sample based on the traces of stone impact points remaining on the sample.
