In April 2026, we were granted a design patent for the dual-head rotary spindle housing, which further enriches our high-end spindle product portfolio and strengthens our competitiveness in automation and dual-head machine application scenarios.

As of April 2026: It owns 11 patents and 12 trademarks, serves hundreds of domestic and foreign companies, and has become a specialized enterprise integrating R&D, manufacturing and foreign trade in the field of precision tooling and fixtures.

This first collaboration with a state-owned enterprise signifies that the company's product quality and overall strength have gained high recognition from a large state-owned enterprise, further enhancing the company's credibility and market competitiveness within the industry.

The local government recognized the company's creditworthiness and development potential, which facilitated subsequent financing and expansion of production.

In 2024, it was officially recognized as a national high-tech enterprise, and its technological research and development and innovation capabilities were recognized at the national level.

The influence of its own brand DGDR continues to expand, making it one of the benchmark brands in the field of precision pneumatic chucks/clamps.

In September 2019, a utility model patent for a rotary chuck was granted, solidifying the technological barrier for rotary precision clamps.

In 2020, four utility model patents were obtained:

1. Anti-jamming inner diameter clamp

2. Anti-jamming chuck with thrust bearing

3. Pull-back pneumatic chuck

4. New type of chuck spindle seat

In November 2021, the company obtained a new type of chuck spindle seat patent, demonstrating its industry-leading integrated spindle and chuck design capabilities.

Obtained import & export license,officially started international business

The addition of several high-precision processing machines has further improved production  efficiency and product accuracy.

On October 25, 2018, the company's registered capital increased from the initial 500,000 yuan to 3 million yuan.

In December 2016, the business address was relocated and expanded for the first time; at the same time, the business scope was expanded.

The company has expanded into new business areas such as automated equipment R&D and mold and fixture manufacturing, upgrading from single component processing to overall precision tooling solutions.

We continuously iterate on core products such as pneumatic chucks, internal support chucks, and spindle seats, forming a small-batch customization capability with stable precision control at the 0.005mm level.

By establishing a stable supply chain and customer base, we are gradually becoming one of the core suppliers of precision tooling and fixtures in South China.
