This year's Technology Forum has selected 22 industry papers, covering the entire industry chain of superhard materials, raw and auxiliary materials, superhard material tools and superhard materials production and processing equipment. Nearly 240 industry experts, scholars and business representatives gathered to share the industry's technology feast.
Zhao Bo, Secretary General of the Superhard Materials Association
The meeting was firstly reported by the Secretary General of the Association, Zhao Bo, "A Brief Analysis of the Development of Superhard Materials Industry in the First Half of 2013 and 2014". The report provides statistical data of national macroeconomic data, main indicators of economic operation of the industry, production of major products, and import and export in the first half of 2013 and 2014 in 17 statistical data sheets. Based on this, a brief analysis of the operation of the super-hard materials industry: economic growth seems to be lower than the national average, the production of super-hard materials continues to grow, synthetic diamond has exceeded 15 billion carats, most products prices have fallen, the import and export market is active However, the high-end market is still occupied by developed countries.
Compared with the national macroeconomic indicators, the growth rate of the superhard materials industry in 2013 was relatively low, which was not optimistic, especially the total profit did not increase substantially, indicating that the profitability of the industry enterprises was far below the national average. However, it is gratifying to note that the productivity of all employees has maintained a nearly double-digit growth rate, indicating that enterprises have made great efforts in reducing staff and increasing efficiency. Overall, China's superhard materials industry has grown steadily from January to June 2014, and it is expected that the indicators will be better than 2013.
Subsequently, the conference entered the technical paper presentation stage, and each technical paper site set up a questioning session to further improve the quality of technical exchanges in the industry.
