Chuangbo Precision Has Obtained A Patent For A Tooling Fixture For Drilling Holes On The Side Of Guide Rails, With Good Processing Results.

Chuangbo Precision has obtained a patent for a tooling fixture for drilling holes on the side of guide rails, with good processing results.

A Zhejiang company obtained a national patent for a small tooling fixture. Hidden behind it was the code for a counterattack to grow its registered capital from 500,000 to 5 million. Information released by the State Intellectual Property Office on April 1, 2025 shows that Lishui, a company established only 8 years ago, has accumulated 15 patent results in related technology research and development.

Humble fixture solves big problem

In machining, drilling holes on the side of guide rails is a common process. However, during actual operation, the workpiece is easily displaced. In traditional practice , special micro-deformation tooling fixtures designed for precision riveting and welding rely entirely on master craftsmen to handle them by feel, making it difficult to guarantee processing accuracy. Under this circumstance, the new clamp developed by this company adopts a double locking structure of side positioning blocks and clamping blocks, making it possible for ordinary workers to do the same work as a master craftsman.

The adjustment slot designed on the bottom plate has many particularities, and it can adapt to guide rails of different specifications. The clamping block moves forward and backward under the drive given by the driving mechanism. It is combined with the side positioning block to form a stable triangular support structure. In June 2024, a patent application was submitted for a special micro-deformation tooling fixture designed for precision riveting , and it took less than a year to obtain the authorization. This speed shows that the technical solution is indeed novel and practical.

Anti-warping of the second cylinder is a miracle

Many drilling fixtures only focus on clamping in the left and right directions, but ignore that upward force will cause the workpiece to tilt. This patent adds a second cylinder to the mounting frame. Chuangbo Precision has obtained a patent for a tooling fixture for drilling holes on the side of the guide rail. The processing effect is good. It presses the upper surface of the guide rail from top to bottom. The downward force exerted by the pressing block has been accurately calculated so as not to cause damage to the surface of the workpiece and to completely eliminate vibration.

Real-life test data shows that after adding this compression structure, the verticality error produced when drilling holes on the side of the guide rail is controlled within 0.02 mm. For ordinary machine tool operators, this kind of accuracy has reached the level of semi-finishing. The efficiency improvement created by the clamp is also particularly obvious. Compared with the traditional method, the time required for clamping is shortened to 40%.

The pragmatic style behind half a million paid-in capital

The information presented by Tianyancha, an industrial and commercial credit inquiry platform, shows that the registered capital of this company is 5 million, but the actual capital paid is only 500,000. Such a situation of capital formation is quite common among start-up companies in the manufacturing field. This means that the company's shareholders are not baselessly and blindly exaggerating, but are making capital investments step by step based on actual demand. Since its establishment in 2018, the company has been able to accumulate as many as 15 patents, with an average of two or more new results every year.

One company has invested abroad and participated in a bidding process. The data provided show that the company is following a path of steady development. There is one piece of trademark information, which means that we have begun to pay attention to brand building. There is only one administrative license, which can reflect from the side that the business scope is relatively concentrated and it is not a blind expansion.

Patent layout reveals market ambitions

Although the specific contents of the fifteen patents have not been fully disclosed, they will be reviewed in conjunction with the disclosed clamp patents and will mainly focus on the field of work clamps. Although this market segment is not large in scale, the demand from machining companies has remained stable. The conversion cycle of clamping patented technology is short, and it can often be applied to production lines within the same year after application.

Although you only participate in the bidding project once, for an enterprise in the start-up stage, if you can win the bid, it means that the quality of its products has been verified by the market. The trademarks and patents shown in the asset clues are real assets that can be used for pledge financing. Once there is a need to expand production capacity, these intangible assets can be exchanged for real funds.

Lishui manufacturing is quietly upgrading

Many people’s impression of Lishui’s manufacturing industry still remains on the special micro-deformation tooling fixtures designed for precision riveting during the small workshop period. This company has 15 patents with 500,000 paid-in capital, which shows that there are already a group of hidden champions in the local area who focus on technology accumulation. The technology promotion service industry is an interesting industry classification, which means that they not only only want to engage in production, but also intend to export technology.

From its establishment in 2018 until the 15th patent was obtained in 2025, 7 years have just passed the survival limit of a start-up. Now that we hold patented technology and have the support of local industrial policies behind it, we can either expand production capacity or seek mergers and acquisitions by large companies. Both approaches are feasible.

The Made in China Code in Work Fixtures

Don’t underestimate this jig used to drill holes for guide rails. It embodies the transformation of Chinese manufacturing from relying on strength to relying on wisdom. In the past, it was difficult to retain the skills of old masters. Nowadays, experience is solidified in equipment through tooling fixtures. Although such incremental innovation is not as eye-catching as chips, it actually improves the efficiency of the factory.

This Lishui company, with a registered capital of 5 million, is not large in the manufacturing industry, but its ability to continue to produce patents shows that the company has found a technological route that suits itself. Those 15 patents are like 15 footprints. They record the growth process of this Lishui company from pure processing to independent research and development.

So in your opinion, in which direction should a company like this that relies on tooling and fixtures develop in the future? Should it choose to continue to focus on market segments to become a hidden champion, or should it choose to expand its product lines horizontally and become a comprehensive service provider? Everyone is welcome to share your relevant opinions in the comment area, and like and forward it so that more people can see the true story of Made in China.
