Dinglong: Grateful for ten years and growing together and moving forward hand in hand

Ten years ago today, Dinglong's color-compatible toner production workshop built with international standards was completed and put into production, and the first batch of color-compatible toners for domestic printers came off the production line. With the birth of the first batch of domestic printer toner cartridges with Dinglong color compatible toner, it also marks a crucial step towards domestic substitution in the field of general printing and copying consumables in China.

Dinglong color compatible toner and compatible carrier are Dinglong's proud product segment. It has achieved domestic substitution with excellent quality and cost-effectiveness, and the cumulative sales volume has exceeded 15,000 tons. The overcoming of numerous technical problems has not only allowed Dinglong to establish a top R&D team in the industry, but also saved tens of billions of procurement costs for China's printing and copying general consumables industry, and improved the competitiveness of Chinese consumables in the global market.

Several times to break through the world-class problems

Ten years of precipitation materials industry "Huangpu Military Academy"

According to the different manufacturing processes, toner is divided into two types: "physical method" and "chemical method". Among them, the "chemical method" toner preparation process is complicated and the technology content is high, which is a technical problem recognized by the world. Before Dinglong broke the monopoly, no company in China had successfully developed it. Downstream compatible finished product manufacturers mainly rely on expensive imported compatible toners.

At that time, the production and technology of color polymerized toner in the world were almost all controlled by machine manufacturers (OEMs), except Japan's "Mitsubishi Chemical", a compatible manufacturer, such as Japan's "Canon", "Konica", "Fuji", "Ricoh", "Xerox" in the United States, etc., and to be sold in bundles with color printers, the color polymerized toner sold in China not only depends on the manufacturer's production schedule but also has to pay for the goods first.

In 2006, in order to break the status quo of being controlled by others, Dinglong established a chemical toner research and development team composed of talents in polymer chemistry, colloid and surface chemistry, powder engineering and other disciplines, and started chemical color compatible toner. Independent research and development of powder projects. In the past 10 years, the 3rd generation of emulsion polymerized toner and the 4th generation of core-shell structure emulsion polymerized toner have been successfully developed; in 2012, according to the market and customer needs, the 1st and 2nd generation of suspension polymerized toner were included in the research and development plan and successfully developed. In the same year, the world's largest and most automated chemically compatible toner factory was completed and put into operation.

In 2014, in line with market changes, 5 to 7 generations of low-temperature fixing polyester toner were developed, which were applied to the new generation of mid-to-high-end machines from Japanese and American manufacturers. The polyester resin synthesis technology for low-temperature fixing in this generation of toner is called the "crown technology" in the toner field. Unlike styrene-acrylic toner, polyester toner can be fixed at low temperature and print faster.

Relying on solid technical accumulation, the Dinglong toner R&D team has conquered the R&D team of hundreds of foreign companies in 2 years, and has taken decades to break through the technical problems, and has become the world's leading manufacturer of color compatible toners. The industry standard of "dry chemical method (polymerization method) color toner" developed by us is not only the benchmark of China's toner industry, but also the best description of the quality of Dinglong color compatible toner. At present, Dinglong's new products are suitable for nearly 20 brand printers and more than 500 series of models from HP, Canon, Samsung, etc., filling the gap in the domestic market of general printing and copying consumables, and completely changing the dilemma that color toner needs to be imported for a long time.

After Dinglong broke the monopoly of toner, Japanese OEM manufacturers changed the toner from "single-component system" to "two-component system" in order to get stuck in the neck of China's consumables industry again, building a technical moat of "carrier" . The carrier is a composite material in which a polymer resin coats a ferrite magnetic core. The toner can be better attached to the developer with the help of the magnetism of the carrier to obtain better printing effect, and the added amount in the toner is less than 10%. It is a new type of material involving multi-disciplinary and multi-background technologies. Many domestic companies give up because of the difficulty of research and development and the long cycle.

At that time, the two links of core material manufacturing and cladding were controlled by different Japanese manufacturers, and they were only supplied to Japanese OEM manufacturers, forming a high monopoly. Dinglong broke the monopoly and became the only company in the world that fully masters the technology from core material sintering to carrier coating technology. The raw materials, production equipment and equipment components have been fully localized.

At that time, Japan's strong technical barriers and business model led to high prices for original color inks, which were sold to China at a price of 1 million per ton. After Dinglong broke the monopoly, the global price of color compatible toner dropped by 80%. Such achievements are inseparable from the support of our partners in the field of general printing and copying consumables in China. The "Pearl of the Consumables Industry" manufactured by Dinglong also gave back to the general printing and copying consumables industry in the most simple way, saving hundreds of years for the industry in 10 years. billion in procurement costs.

For Dinglong, in the process of developing compatible color toners and carriers, the top technologies and talents in material research and development, engineering and quality management have also been precipitated, and they have gained a "Huangpu Military Academy" in the material industry. ” will continue to supply blood and oxygen for the research and development of other Dinglong materials.

Cooperation and competition coexist

Helping the sustainable development of China's consumables industry

Because it has mastered color toner, the key material upstream of printing and copying consumables, Dinglong purchased from the downstream with the thinking of building a whole industry chain, opened up the industry chain, and became a full-industry chain enterprise in the field of general printing and copying consumables in China. In order to integrate the most advanced toner technology in China, Dinglong will merge and upgrade Dinglong (Ningbo) New Materials (formerly known as Ningbo Freestone New Materials Co., Ltd.), increasing the number of Dinglong color compatible toner production lines from 6 To 13, the annual production capacity reached 3,500 tons.

"Dinglong has made outstanding contributions to China's office consumables industry, which is the pride of Dinglong and the pride of Chinese enterprises." On the tenth anniversary of Dinglong's toner and carrier production, representatives of several cooperative enterprises sent a message Congratulations. Looking back on the ten years of Dinglong color compatible toner in the consumables market, from emerging to the top, the most important thing is to win the trust and support of customers.

Zhuhai Tianwei Pegasus Printing Consumables Co., Ltd., as the leading enterprise of consumables in China, is also the first customer of Dinglong printer color compatible toner. It took the lead in trying domestic substitution and recognized the domestic quality. Ninestar Co., Ltd. has cooperated with Dinglong since 2006 when it entered the printer-compatible toner cartridge. With the recognition of leading companies in the industry and the rapid development of the domestic general consumables industry, more and more industry partners choose Dinglong. Dinglong broke the monopoly of toner materials overseas for many years, and the direct impact on China's consumables industry is the reduction of procurement costs. However, the deep reason for long-term cooperation with industry customers lies in Dinglong's strict management of toner quality and its rapid response and service capabilities to customer requirements.

In the process of accelerating the replacement of localized toner, we have to mention Zhuhai Zepeng Printing Consumables Co., Ltd. As a service provider for the last mile of Dinglong toner, Zepeng has been deeply involved in the industry for ten years, expanding domestic and overseas markets, and increasing the share of domestic toner in the consumables market. After long-term tacit cooperation, Zepeng and Dinglong have won the recognition of industry customers by constantly understanding customer needs, improving products, and using continuous improvement products and unremitting services.

Dinglong has established industry standards for China's printing products together with various industry partners, and has made pioneering exploration and practice to promote the healthy development of the industry. With the layout of partners in the field of domestic Xinchuang, Dinglong will also invest more R&D resources in toner products to help partners flourish. In the future, Dinglong will continue to achieve new breakthroughs in the field of toner and lead innovation together with the printing and imaging industry.
