Continuous Innovation, Moving Towards High-End

In April 2026, we were granted a design patent for thedual-head rotary spindle housing, which further enriches ourhigh-end spindle product portfolio and strengthens ourcompetitiveness in automation and dual-head machineapplication scenarios.

As of April 2026: It owns 11 patents and 12 trademarks, serves

hundreds of domestic and foreign companies, and has becomea specialized enterprise integrating R&D, manufacturing and

foreign trade in the field of precision tooling and fixtures.

Strength Reaches New Heights

This first collaboration with a state-owned enterprise signifiesthat the company's product quality and overall strength havegained high recognition from a large state-owned enterprise,further enhancing the company's credibility and marketcompetitiveness within the industry.

The local government recognized the company's

creditworthiness and development potential, which facilitated

subsequent financing and expansion of production.

National High-tech Enterprise Certification & Brand Leap Forward

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.

Technology upgrades and intensive patent licensing

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

Major upgrades (capital, facilities, foreign trade)

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.

Capacity expansion and upgrade

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 andfixture manufacturing, upgrading from single component

processing to overall precision tooling solutions.

Deepening Technology, Steady Development

We continuously iterate on core products such asforming a small-batch customization capability with stableprecision control at the 0.005mm level.

pneumatic chucks, internal support chucks, and spindle seats,

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.
