Material: steel
Process:Lost wax process, Lost foam process, shell mould
Casting surface roughness:Ra6.4~12.5
performance feature:
1.Greater design flexibility
This design has the largest selection degrees of freedom on the shape and size of casting. It is specially for complex shape and hollow section castings. And steel castings can be made by the unique core casting process. The deign is easy to shape and can quickly produce finished products as drawings. The delivery time is short.
2.Strongest flexibility and variability of metallurgical manufacturing
You can choose a different chemical composition and organization structure to meet the needs of different projects.Different mechanical properties can be realized by using different heat treatment process. This feature can improve the weldability and workability.
3. Improve the overall structural strength
Weight reduction design and a shorter delivery time can improve the competition advantage in price and economic aspects.
4.Wide range of weight change
Small steel castings may only 300 grams, and large steel castings can be up to several tons, dozens or even hundreds of tons.

"International Finance News" quoted the national semiconductor lighting industry engineering research and development and industry alliance (CSA) executive deputy secretary general Jun Jun pointed out that with the LED technology continues to make breakthroughs and mature, technical performance, especially the improvement of luminous efficiency is not LED The biggest obstacles and appeals of lighting applications, but market-oriented promotion of the industry's most important factors to further advance. He believes that in the past two years, the problem of overcapacity and lack of core competitiveness in the developing industry should establish a platform for communication, coordination and integration and an integrated service model and carrier.
The report quoted another industry insider as saying that after the 2012 downturn, the price of LED upstream chips dropped sharply. The price of LED products has been falling this year, and some LED lighting products are close to the price of compact energy-saving lamps, which has an initial advantage.
Some relevant business people pointed out that from the current situation, their performance is indeed better than 2012, but still expect the government to give more subsidies to this emerging industry. There is also a view that there are more than 5,000 companies in the LED industry with less than 200 billion yuan in the current billion, and the concentration is low. In the future, we must be prepared for the upcoming industry mergers and acquisitions.
