    Technical Requirements

Advantages

We have years of research and development experience in the shaft industry, and customize high-quality shafts for you
High lifespan

By using imported materials and combining them with a unique multi friction surface, the notebook has undergone rigorous testing, resulting in a lifespan of up to 25000 times for opening and closing.

More precise

The components of the shaft are divided into hardware and automotive parts.

High salt spray

Our products can pass the 24-hour salt spray test, with some products reaching up to 720H. 

High standard

Using unique powder metallurgy environmentally friendly materials, after vacuum heat treatment, the hardness is higher and more wear-resistant.

Customizable

The product structure, surface color, and coating can be customized.

High technology

ZGSOCEN has developed a 360 degree rotating watch chain notebook pivot, which inherits Taiwanese craftsmanship and is composed of 108 parts made of pure steel 304.
