Our Advantages

Cylinder Material

Choose the best Material 20 CrMo 40 CrMo 42Crmo, The material of the middle cylinder is made of 20crmo, and is processed by a high-precision CNC center; after the processing is completed, the cylinder undergoes leading heat treatment technology. We have our own heat treatment workshop; the matching tolerance of the piston and the middle cylinder is within 5-7 wires, and each middle cylinder Both the piston and the piston are cold treated with liquid nitrogen to prevent the cylinder from expanding due to excessive oil temperature and cannot be used normally.

High quality hammer shell and splint

The material used for the hammer shell and splint is wear-resistant, manganese steel material, ensure that it will not crack.We use high-precision product matching, and the matching tolerance is within 1-5 wire, which fully guarantees the hammer's striking strength.The material of the whole body bolt and splint bolt is 42crmo, and each one is heat-treated to prevent each bolt from being elongated and deformed.

The chisels are made of high-strength material 42CrMo with good wear-resistance, high toughness, and long service life.
The chisel needs to withstand high-frequency impact, extrusion and friction during work, so it must have high hardness, wear resistance, fatigue resistance and certain toughness. Heat treatment can optimize the mechanical properties by changing the internal microstructure of the material to meet the working conditions.
