The report said: The country's macro-economy has entered a new normal, with slower growth, higher efficiency, greater transformation and upgrading, and the introduction of new policies to regulate the market. In particular, the regulation of real estate has caused many industrial fields to feel pain and development has been greatly affected. Under the influence of the big situation, the super-hard materials industry has changed its long-term strong development momentum and has been under unprecedented development pressure. Like the national macro-economy, it has entered a medium-speed development with a nominal growth rate even lower than GDP. The output of large enterprises increased their income and the profit rate decreased. The SME market and profit margins were severely squeezed, and it was difficult to maintain operations and even cut production and stop production. However, the enterprises with rapid and good transformation have sprung up everywhere, new products are constantly changing, and the situation is gratifying.
The report pointed out that the output of major products in China's super-hard materials and products industry has risen steadily, market competition is fierce, and profit margins have generally declined. However, the import and export market is active, especially the continuous growth of exports, which provides a certain positive space for the development of the industry.
The report also pointed out that in 2014 China's diamond production reached 16.8 billion carats, a growth rate of 11.3%, the average unit price of diamonds decreased by 3.4% to 0.28 yuan / carat; CBN production reached 570 million carats, a growth rate of 29.5%, the average unit price of CBN rose 5.9% , is 0.72 yuan / carat.
In the report, the statistical commodities are divided into four categories: diamond, diamond grinding wheel, diamond circular saw blade, and super-hard material cutting tool. Diamond saw blades account for nearly half of the total, which is the largest export of superhard materials and products in China. Due to the different export tax rebate rates of different commodity numbers, enterprises should declare goods with high export tax rebate rate as much as possible, and the commodity numbers used by local customs for similar products are different. Diamond saw blades are sometimes exported under other tools, so the actual export volume may exceed half of the total.
The report pointed out in the conclusion: (1) Although the output of superhard material single crystal has increased, it is slightly lower than the nominal growth rate of GDP. It has been under pressure to develop the beauty of the past 30 years, which is much higher than the growth rate of GDP. In recent years, CBN has developed rapidly with the development of precision machining, and the market demand is very promising. However, because its total volume is too small, it contributes little to the development of the entire industry. The macro economy is not working, the real estate situation is not good, and China's super-hard materials and products industry is unlikely to come out of the trough. (2) Although the export situation of the industry products is good, there is no big change in the high-input and low-out situation. The unit price ratio is: saw blade 2.6, diamond 2.8, grinding wheel 19.4, cutter 20. It can be seen that the transformation and upgrading is urgent, surpassing the advanced responsibility! (3) The long-term development prospects of the industry are bright and the support is insufficient in the near future! Strengthening research and development, hard work and continuous innovation are the foundation of development! Studying the market, discovering gaps, and taking the road of differentiated development is the blessing of SMEs! High-precision products are the heavy lifting device! (4) China's super-hard materials and products industry has a large number of outstanding scientific and technological talents, and has a large and perfect industrial base. As long as we persist in our unremitting efforts, we will be the first to achieve the great goal of strengthening the super-hard materials!
The product uses own mold to make technologic design, the housing uses aluminum and silicon alloy and upper protrusion and lower sinking structure is used so as to ensure good sealing performance; protective grade reaches IP 68.
Main parts are imported, wiring bar is welded with precise anti-surge electronic components, which can prevent Load Cell damage caused by lightning and power grid surge voltage.
Whole device uses stainless steel grounding bolts to ensure reliable grounding during operation.
Assembly of junction box uses not-loose screws so as to avoid loss during load cell wring.
Wiring board uses combined screws for assembly, which are convenient for removal.
In order to ensure protective effect, force and diameter of tightening parts have introduction.
