Qiaotou Town boasts a vibrant industrial ecosystem and convenient transportation conditions, which are conducive to the procurement of raw materials and the sales and distribution of products.
Initial Stage: Product R & D and Market Penetration (2009 - 2014)
In the first five years, the company focused on enhancing its R & D capabilities. It recruited a group of professional chemists to develop core products such as phosphoric acid, sodium hydroxide, citric acid, white spirit, titanium dioxide, soda ash, and sodium carbonate. Meanwhile, the sales team began to explore the market, with the main target customers being local manufacturing enterprises in the Pearl River Delta region. By participating in local industry exhibitions and trade negotiations, the company gradually increased its brand awareness and established initial business relationships.
Product Line Expansion and Business Scale Enlargement (2015 - 2020)
As the company gained a firm foothold in the market, it expanded its product line. New products such as environmental pollution treatment agents, metal surface treatment agents, and release agents were added. To meet the growing market demand, the company expanded its production facilities, introduced advanced production equipment, and optimized the production process. During this period, the company also started to explore online sales channels, using e - commerce platforms to reach a wider customer base across the country.
Service Strengthening and Technology Upgrading (2021- Present)
In recent years, Weiqi Chemical has been committed to improving the overall service level. The company has established a complete after - sales service system to solve customers' problems in a timely manner. In terms of technology, the company has continuously invested in R & D to promote the development and promotion of new material technologies. The company has also carried out cooperation projects with scientific research institutions to enhance its technological innovation capabilities.
