Product Advantages
Precision Machining
Measure and process using precision machine tools and measuring tools under strictly controlled environmental conditions.
High-quality Carbon Steel (35#/45#)
With long life, low heat generation, high hardness, high rigidity, low noise, high wear resistance and other characteristics.
Cost-effective
The use of high-quality carbon steel steel, after precision processing and forming, greatly improves the user experience.
Surface Treatment
BLACK
Black is a common method for metal heat treatment. The principle is to make an oxide film on the metal surface to isolate the air and achieve rust prevention.
