Deepening in New Materials and Creating 'Fine Powder'
In midsummer, everything in Tonghua is flourishing. Tonghua seeks motivation from technological innovation, developing new productive forces according to local conditions, and gathering a powerful momentum for Tonghua's high-quality development. Awarded as a national 'little giant' enterprise specializing in special and innovative fields, a national high-tech enterprise, a national key new product winner, and a '13th Five-Year Plan Key R&D Project' undertaking enterprise, it owns a provincial enterprise technology R&D center, has obtained 7 national invention patents, and over 130 proprietary technologies... This is Tonghua Hongxin Abrasive Materials Co., Ltd., which has been deeply involved in abrasive materials for over 40 years. Currently, the company's green silicon carbide micropowder series products have been exported to Japan, Germany, Malaysia, South Korea, and other countries, and have established a sales network in more than 10 provinces and cities in China. Recently, the reporter visited Tonghua Hongxin Abrasive Materials Co., Ltd. located in Guosong Town, Tonghua County, feeling the historical accumulation and vitality burst of this 'time-honored' enterprise. In the company's loading and shipping area, 20 bags of semiconductor cutting edge powder with a model number of 2500# are neatly stacked, each bag weighing 1 ton, and workers are loading them one by one with forklifts, preparing to ship them abroad. 'In the first half of this year, the order volume for the company's four main models of semiconductor cutting edge powder has exceeded 2,600 tons, all of which are exported to the world's top three chip manufacturers, with a market share of over 40% abroad. Ultra-fine silicon carbide powder is mainly sold to more than 10 provinces and cities including Zhejiang, Shandong, Guangdong, and Sichuan, with a domestic market share of over 30%,' said Mo Zhenghao, the company's person in charge. Moving towards 'new' with 'quality'. The stable market sales benefit from consistent quality adherence. The company's leading products are semiconductor cutting edge powder and silicon carbide ceramic raw material powder, using self-patented production processes, German imported equipment, and an advanced and comprehensive testing system. This ensures that the powder has characteristics such as high purity, small particle size distribution range, high and adjustable specific surface area, stable chemical properties, high thermal conductivity, and low thermal expansion coefficient. In 2023, the company invested funds for a new round of upgrades and transformations of workshops, equipment, and roads, fully ensuring product quality stability and adaptability to customer requirements. Entering the cutting edge powder workshop, one can see workers pouring silicon carbide powder into the feed bin, going through purification processes to remove impurities like iron and carbon, forming material cakes. The powder in the material cakes is then classified through conical grading tanks, enters sedimentation tanks, and is managed by color classification. Each link has quality control personnel for sampling and testing, ensuring strict process quality control. 'Color classification management is both for dust prevention and error prevention. Plastic sheets in white, red, blue, and black correspond to different product models, so there is no confusion. The powder in the sedimentation tank is sorted, dried, mixed, and tested, ready for warehouse packaging and shipment. The entire process is strictly implemented according to ISO9001 quality management system standards, always adhering to the 'Three No Principles,' namely: do not accept defective products, do not produce defective products, and do not let defective products flow out,' Mo Zhenghao explained eloquently when talking about product quality control. In 2023, the company's sales reached 130 million yuan, doubling the output value compared to 2022. This year, the company has participated in professional exhibitions and forums in Germany, Japan, Guangzhou, Shanghai, Changchun, and other countries and cities, constantly expanding new customers, and it is expected that annual sales will reach 200 million yuan. Technological innovation is the 'solid foundation' for promoting high-quality enterprise development. At the company's technology R&D center, technicians are busy with experimental testing in front of the equipment, occasionally recording some data. The company has successively carried out industry-university-research cooperation with the Changchun Institute of Applied Chemistry of the Chinese Academy of Sciences, the Shanxi Coal Chemistry Institute of the Chinese Academy of Sciences, and Northeastern University, ensuring the enterprise always masters key core technologies and maintains an internationally advanced technical level. Over the years, the company's R&D team has also undertaken the national '14th Five-Year Plan' key R&D project, the '863 Plan' project, the 'Torch Plan' project, and multiple 'Innovation Fund' projects, injecting new momentum into the enterprise with technological innovation. 'Currently, the company is stepping up research on high-purity ultra-fine silicon carbide powder for semiconductor processes. Small test samples have been successfully developed and are expected to be put into production within three years. In the future, a new R&D center and an employee center will be built, attracting more high-end talents. The company also plans to do deep processing, further develop and extend the industrial chain, and show new achievements in strengthening, supplementing, and extending the chain,' said Mo Zhenghao confidently when talking about future development.
