XHB-3000 Type Digital Display Hardness Tester

Testing Parts

Casting of floor spring and its casting parts, Door closer outer covers, aluminum covers  etc.

Purpose

It is used for hardness testing for raw materials like floor spring  crusts and its casting parts，the outer covers of floor springs , door closer covers and aluminum covers etc. This device is usually used for hardness test for iron, steel, non-ferrous metals soft alloys and other metal materials, besides, it also could be used for hardness testing to plastic, bakelite and other non-metal materials.

HR-150DT Type Electric Rockwell Hardness Tester

 Testing Parts

Spindle, Steel bushing, Roller wheel, Pulling pin of Floor spring, and Gear of door closer,etc.,

Purpose

Hardness is one of the important index for mechanical materials, like spindle, steel bushing, wheel, pulling pin of spring,and gear of door closer,etc., after the heat treatment, hardness on surface of these materials all need to be tested by being beaten. Metal hardness is related with other mechanical performance,and can be known the strength, fatigue, creep, abrasion and so on through testing it.
