Corporate Development History
LG™ Brush | Opportunities are offered by the times. It takes people to seize them — a group of like-minded individuals, and work done steadily one thing at a time.
In 1997, Wang Chengfeng and his wife left Ningguo, Anhui Province, for Shanghai. Ningguo is a small county in southern Anhui with a modest population. Setting off from there, they settled at No.4 Zhenda Road, Baoshan District, Shanghai.
That year, they had next to nothing — only a rented workshop, where they handmade civilian brushes. There were no production lines, no offices, nor any “departments”. Staff came and went, and they never managed to build a proper team.
So he was the entire sales department. He was the one exploring the market, handling orders and making deliveries. He spent his days visiting customers and returned to the workshop at night. In this one-man business, there was no division of labour — only tasks to be done one after another.This went on for five years. A company that survives five years yet remains stuck in the same place is usually not for lack of effort. Instead, its founders have already seen the ceiling of this business. Demand for civilian brushes was limited. No matter how hard they tried, they could only sell the same products to more people.
The turning point came at an exhibition in 2002.
Wang Chengfeng spotted a “similar product”. Similar, but only superficially. It was still a brush, with bristles much like the ones he knew — yet its purpose was entirely different.
This brush was not made for cleaning. It was designed for grinding and deburring. A brush could be an engineering tool, not merely an everyday commodity. That was the first realization he had that day.
What shaped the next two decades, however, was the second insight: Bristle materials were not limited to nylon and animal hair.
This may sound like common knowledge today. Back then, for someone who had spent five years hand-making civilian brushes, it was a fundamental cognitive breakthrough.
That was why he made up his mind to take another step forward.
If bristles were limited only to nylon and animal hair, then the so-called “industrial brush” would merely be a sturdier civilian brush — a category that involved harder work, slightly higher pricing, yet remained essentially unchanged.
But bristle materials could be something else. This meant what a brush can do, and how much workload it can handle, depends on what the bristle filament is made of.
This was no longer just business. This was technology.
From that day on, his focus was no longer on “making more brushes”. What he truly aimed to do was make the right brushes and supply them to people who needed them.
Later, he began researching and manufacturing genuine "industrial brushes", and orders gradually came in.
Yet new challenges emerged. A workshop built for handmade civilian brushes was taking on industrial brush jobs, and none of its production capacity, quality control or delivery schedules were systematic.
A job that could be completed today might not be achievable tomorrow; one batch that passed inspection might not guarantee the next. This was not an issue of attitude. It came down to factory premises and equipment.
In 2004, Wang Chengfeng purchased seven mu of land in Ningguo. The funds came from savings accumulated over his years making civilian brushes, and he invested every penny. This was the first time he staked everything on a single decision.
The factory was built in Ningguo to cut costs and boost efficiency. Sales operations remained in Shanghai to stay close to customers. The two locations work in efficient synergy, growing the company step by step. This structure has been maintained from 2004 to this day.
It was also in this year that he chose the brand name: Longguang. Long signifies “prosperous business”, and guang means “bright future”. It also subtly references polishing — the core work the company would later become known for. Its external English abbreviation is LG, derived from Longguang.
In 2004, Longguang could for the first time declare publicly: We are a formal, qualified physical enterprise.
After the factory was established, LG gradually connected with three major enterprises through online channels: Bosch, Samsung, and Gree Group. These three customers held their suppliers to rigorous standards. From sales to production, procurement and finance, every step required defined processes, documented records and full traceability.
What they wanted was not simply a better brush. They wanted a supplier less prone to errors. Go one layer deeper: they wanted a partner who could understand their real needs and keep up with their requirements consistently.
Guided by these requirements, LG developed its own set of SOP procedures, sparing no effort or resources. The payoff was long-term partnerships with major clients, stable and controllable quality, and the trust of customers — who were willing to recommend us to their sister companies.
By this point, Longguang Industrial Brush Co., Ltd. had taken a major step forward toward becoming formal, professional, reliable and accountable.
The factory was founded in 2004, and the first machine Longguang purchased came from WÖHLER, Germany.
A large number of domestically-made equipment were also procured. All machinery was fully owned by the company. With self-owned equipment, we could tailor processes to our own requirements. Rented machines, by contrast, only ran standard workpieces and could not accommodate custom ideas.
In 2012, Longguang began purchasing additional machinery from Germany and Italy. Our technical team made frequent trips to equipment manufacturers, visiting WÖHLER in Germany and ZAHORANSKY. These two separate visits fueled continuous technical refinement.
All the technical accumulation ultimately comes down to a single filament.
We started by purchasing ready-made filaments, and later moved on to self-developed abrasive filaments: silicon carbide, alumina, white ceramic, ceramic fiber and diamond, with grit sizes ranging from 80# to 1000#. Among them, ceramic fiber filaments can machine workpieces up to HRC 65 hardness.
A single filament varies from coarse to fine, soft to hard. On the same machine, simply switching to different filaments delivers entirely different surface finishing results. This is Longguang’s true competitive moat.
Therefore, when customers come to us with their workpieces and operating conditions, what they receive is not a static product catalog, but a fully customized filament specification tailored to their needs.
Since 2012, LG has put quality first and invested heavily in R&D — all to make every single brush right and earn the lasting trust of our customers.
Over the years, led by our team of professional engineers, the R&D team has achieved significant breakthroughs. We have not only refined existing high-quality filaments and brushes, but also developed a wide range of proprietary products. These efforts have earned us high-value certifications including ICAS, SGS and ISO, as well as multiple utility model patents.
2023 — LG was certified as a National High-Tech Enterprise. Certificate No. GR202331004739, jointly approved by the Shanghai Science and Technology Commission, Shanghai Finance Bureau, and Shanghai Tax Service of the State Taxation Administration.
We began applying for patents in 2021 and have successfully obtained more than 20 patents to date.

With products in place, a strong engineering team built, and the business scaling up, LG has grown into a leading industrial brush manufacturer in China. Now it is time to look beyond — to step into a bigger, wider world.
Exporting started much earlier than many people assume. Back in 2010, LG was already handling export orders through trading intermediaries, shipping to Japan and South Korea.
But back then, the focus remained on the domestic market. Export business was just a side activity. There was no brand, no dedicated international sales team, no dedicated customer acquisition channel...
In 2018, with the technical and sales teams expanding, the company purchased a standalone office building of over 1,000 square meters in Nanxiang, Jiading District, Shanghai — Building G, No.2, Lane 819, Yinxiang Road. This is the Shanghai headquarters today. That same year the Shanghai sales team was split into a domestic trade division and an international trade division. Domestic business stayed with the domestic team; overseas business was built from the ground up. This marked a new phase — LG had officially stepped onto the global stage
Today, LG’s export markets cover the Middle East, the European Union, Japan, South Korea, Malaysia, Singapore, Thailand, Vietnam, Indonesia, the United States, Canada, Mexico and Brazil.
LG has its own local agents in Ontario, Canada; Texas, USA; and Monterrey, Mexico. The Monterrey agent also covers neighboring Latin American markets. In all these markets, Longguang remains the manufacturer. The agents handle import, inventory and frontline technical support — but they do not change who makes the product.

Wang Chengfeng is a familiar figure on the shop floor at the Ningguo factory, at LG’s Shanghai headquarters, in the offices of the frontline R&D team, and at a wide range of relevant industry exhibitions.
Fifteen years ago, he sat face-to-face with customers at a trade show. Today, he stands at his own booth, pointing to the brush discs on the display wall. Put the two photos side by side: the setting has changed, the products have changed — yet he is still doing the exact same thing.
Wang Chengfeng is a dedicated and responsible leader. He stays close to production, R&D and frontline sales, always keeping a clear vision for LG.
Guided by his perseverance, the team keeps refining industrial brush products and expanding global markets. His down-to-earth spirit inspires every member to pursue reliable quality and long-term growth.Wang Chengfeng is still based at the Ningguo factory today. He oversees the entire new plant, optimizes the organizational structure, and leads new product development. He remains on the front lines, rather than staying confined to a “chairman’s office”.
Counting from the small workshop at No.4 Zhenda Road back in 1997, it has been twenty-nine years. As he puts it, after these 29 years in the brush-making business, everything boils down to two core beliefs.
First: “Ours is a niche industry, yet an indispensable component for precision machining.”
Second: “Our vision is not merely to be a fleeting enterprise that profits from the dividends of the era. Instead, we aim to root ourselves in China, reach out to the world, and truly build a century-old enterprise.”
In 2019, LG secured land in Ningguo to build its second factory.
In 2020, the official property ownership certificate was issued. The land covers an area of 13,143.2 square meters, with a total building floor area of 14,926.89 square meters. The structure is a four-story reinforced concrete building. The certificate number is Wan (2021) Ningguo Real Estate Rights No. 0014390, and the land use right runs from August 5, 2020 to August 4, 2070 — a span of fifty years.
Construction began on July 27, 2021. In 2023, the new factory officially went into production. From land acquisition to production: four years.
Shanghai headquarters, the original Ningguo factory and the new Ningguo plant — all purchased with self-funded capital, none of the premises are leased. Owning our factory buildings eliminates risks of rent hikes and relocation. There will be no scenario where production lines must halt simply because the landlord plans to raise rent the following year.
We have 14,926.89 square meters of self-owned factory space, equipped with machinery imported from Germany and Italy. Continuous investment has been maintained since 1997. LG operates one of the largest manufacturing facilities within China’s brush industry. We plan to build an additional 5,000-square-meter workshop as Phase II expansion in the next three years.
