1、 Product Name:Leather cold crack impact testing machine（ALaw)

2、 Product model:JX

-20913、 Product performance

1Features and specifications:、

Purpose:

2This machine is mainly used to test the leather surface coating, which generates an impact energy of 4J when dropped at a certain height with a 1.8kg impact hammer at low temperature. The surface damage of the sample is observed and evaluated. The height adjustment is manually and electrically controlled, and the hammer dropping method is controlled by an electromagnet.、Design standards:
