Recently, the launching ceremony of the domestic semiconductor lighting industry leader system was held in Guangzhou. It is reported that the front runner system is divided into the production end and the product end. The production end is around the production link, and the minimum energy consumption is guided by the chip, package, module, etc.; the product end refers to the mature application products provided to the end user, such as street lamps, Tunnel lights, etc., guide the highest application energy efficiency of these products. Through the periodic assessment of the energy consumption levels of the production links and their end products in the LED industry chain, the enterprises with the highest energy efficiency production level and the most energy-efficient products are positioned as the front runners, and are dynamically adjusted periodically.
According to industry insiders, the development of LED lighting from a small industry to the scale of one or two thousand companies today can be described as a decade of hard work, but in many cases even people in the industry are difficult to distinguish between good and bad. The Guangzhou International Lighting Exhibition in 2014 has arrived again. Everyone is dazzled. Some enterprises with an annual output value of 30 million have spent 3 million exhibiting, and the products are also uneven. Therefore, the healthy development of the LED industry must be inseparable from the guidance of the state.
The establishment of the front-runner standard system has been clearly stated in the “Twelfth Five-Year Energy Saving and Emissions Comprehensive Work Plan†issued by the State Council in 2011, including research to determine the advanced level of energy efficiency of high energy-consuming products and end-use products, and to develop a leader. Energy efficiency standards.
In May 2012, the State Council executive meeting decided on policies and measures to further promote the consumption of energy-saving appliances, proposed the implementation of the energy efficiency leader system, published the catalogue of energy-efficient front-runners, and gave higher subsidies to ultra-efficient products that achieved the leader's energy efficiency indicators. The leader's energy efficiency indicators are included in the energy efficiency standards.
At present, the semiconductor lighting leader system has no conclusion on subsidies.
According to Wu Ling, secretary-general of the National Semiconductor Lighting R&D and Industry Alliance, the semiconductor lighting leader system hopes to promote the development of the industry through the market, so as to promote environmentally friendly energy-saving products, and at the same time cultivate famous brand enterprises through such methods. To guide the LED lighting industry to develop in a healthier direction.
Liu Bing, director of the Industrial Development Division of the Ministry of Science and Technology of the Ministry of Science and Technology, said: Recently, the State Council is further developing a series of documents to promote the development of related service industries, while the Ministry of Science and Technology will focus on R&D, design and technology transfer, transformation of results, entrepreneurial incubation, and technology. The technical service industry that has positive effects on technological innovation and industrial innovation in financial services, intellectual property services, and testing services will actively promote and provide effective support.
our dished heads are used in a variety of applications and industries such as storage tanks, pressure vessels, road tank, food processing operations, chemical plants ,Nuclear operation, Oil Refining, Architectural feature, power generation.
Due to our forming experience and equipment, we can spin or press the first part of the process of forming your products, It depend on the thickness and material performance,
Our main products are 2:1 SE dished heads, Torispherical heads, Cones,Hemispherical Heads etc
Choosing the right type is the key decision for each customer and one for which our experience team to happy to give advice, simple speaking, the torispherical heads, the less ressure it can withstand, Conversely, the deeper dished heads, for example Elliptical heads, hemispherical, the greater pressure it can take.
Our in house-capability to form dished heads by cold press brings major benefits to our customers and sets us apart from others dished heads manufactures
For carbon steel dished heads, we can forming this dished heads from 76-9000mm in diameter and below 250mm in thickness
The general forming process as the below sketches 
Technical Delivery Condition
1,Our material (hot Rolled Unalloyed structural steel, high and low temperature steel, High Alloy steel)
We have no carbon steel plates in our stock and most of plates are from Chinese steel market or mill. Meanwhile As Japanese owed company, We can also source the plates from Japanese ex-mill if end user can`t accept ex-chinese mill.
Basically the delivery time shall be below 20days for dished heads if plates are from steel market. and Max plates width from them is below 2200mm. it means that the seamless dished heads diameter shall be below about 1800mm.
The max width CS plates that Chinese mill can do is below 4700mm,and dished heads can be seamless below 3800mm in diameter.
2,Enquiry/order required information
We can give our clients once they gave us the below information
But if clients tolerance is higher than below Hokkai standards, it shall be provided to Hokkai prior to offer or ordering.
