On September 9, 2015, Corning hosted the 35th anniversary media meeting in Beijing. As a market leader in global optical communications, display technology, environmental technology , life sciences, and specialty materials, Corning entered China with television technology and consumer products in the 1980s. Over the past 35 years, Corning's business in China has grown rapidly from the initial display technology to the comprehensive layout of the five business units, from the offices of six individuals to Greater China with over 5,000 employees. During the past 35 years, Corning, while growing up, has been providing services and services to Chinese customers through the provision of innovative technologies and solutions.
Li Fang, President and General Manager of Corning Greater China
At the 35th anniversary media meeting, Li Fang, president and general manager of Corning Greater China, stated: “For Corning, China is one of the strategically important markets and the only market with five major business units except North America. We are optimistic about the potential and future development of the Chinese market and will use more innovative technologies and products to develop together with Chinese customers and the Chinese market.â€

At the event, through the 35-year short film developed by Corning in China, the China Truck Network reporter also learned about the changes that Corning’s innovation has brought to our lives, especially in the environmental field. At present, environmental pollution is still a problem we face, and haze has seriously affected people's lives. In the environmental technology display area of ​​Corning China, the China Truck Network reporter saw a filter carrier for controlling automobile emissions, a particulate filter for heavy-duty diesel vehicles, and an ultra-thin wall carrier for light-duty gasoline vehicles .
In response, Wu Dan, general manager of the Department of Environmental Protection at Corning (Shanghai) Co., Ltd., told the China Truck Network reporter: “These filter carriers purify 90% of air and play an important role in reducing vehicle exhaust pollution. In the 20th century, In the early 1970s, Corning took the lead in introducing the first set of mobile emission control solutions to determine the standards of global catalytic converters. Since then, Corning Environmental Technology has been a major contributor to air cleaning. Today, we are still committed to The creation of advanced ceramic carriers and particulate filters will increase the performance and efficiency of the engine to a new level and further reduce exhaust pollution."

Corning's filter carriers currently include ceramic supports, particulate filters, and ceramic supports and filters for stationary applications. The first two are mainly used in the automotive sector, the latter being used for stationary catalytic systems to help control air pollution from power plants, refineries, chemical processing plants and many other industrial applications.
Ceramic carrier:
The Corning ceramic carrier forms the core of the catalytic converter and achieves efficient emission control by converting harmful pollutants (hydrocarbons, CO and NOx) emitted by light, medium and heavy vehicles.
Corning® Celcor® distribution carrier for gasoline and diesel vehicles
Corning® FLORATM Carrier for Gasoline and Diesel Vehicles
Corning filter carrier for controlling automotive emissions
Particle filter:
Corning's particulate filters are used in emission control systems to remove particulate matter (soot) from exhaust emissions.
Corning® DuraTrap® AT filters for light, medium and heavy vehicles.
Corning® DuraTrap® AC filters for heavy duty diesel vehicles.
Corning® DuraTrap® TW Filters for Heavy Duty Diesel Vehicles
Corning® DuraTrap® GC Filter for Light Gasoline Trucks
These products are produced at the Jinqiao Industrial Park in Pudong, Shanghai. It is a modern high-tech factory that provides products and services for Corning's global customers. The plant went into production in 2000 and completed expansions in 2007, 2012 and 2014. According to Zhang Jun, Corning heavy-duty diesel vehicle business director, Corning China is expanding the production of heavy-duty diesel emission filter carriers to meet the environmental protection needs of China's heavy-duty diesel vehicles.
Corning Automotive Emission Filter Development Process:

1974 - The first commercial Corning carrier delivery for the 1975 model.
In 1998, Corning introduced the first thin-walled carrier with a larger geometric surface area to help improve conversion efficiency.
1999 - Corning introduced the first ultra-thin-wall carrier to facilitate the design of more efficient catalytic converters.
2005 - Corning introduced the DuraTrap® AT filter for light-duty diesel engines.
2005 - The inventors of honeycomb ceramic carriers Rodney Bagley, Irwin Lachman and Dr. Ronald Lewis received the National Medal of Technology.
2006 - Corning launches the DuraTrap® AC Filter, the first mass produced cordierite filter.
2007 - Corning launches the Celcor® 600/2 carrier, the next generation ceramic carrier for light gasoline and diesel vehicles.
2012 - Corning launches DuraTrap® AT LP filter for light diesel vehicles.
2014 - Corning launches DuraTrap® AT HP filter for light diesel engines and DuraTrap® TW filter for heavy duty diesel engines.
2015 - Corning launched the FLORATM carrier to reduce the cold start emissions of light vehicles and introduced the DuraTrap® GC filter for direct-injection gasoline engines.
High Precision Machining is defined as a process of changing the dimensions or the performance of workpiece with machining facilities.
According to the temperature of the workpiece while in machining, high precision machining can be divided into cold working and hot working. Usually, machining under indoor temperature, and won't change cause chemical change or phisical phase change is named cold working. On the other hand, if under temperature, higher or lower than room temperature, which will lead to chemical changes or phase changes, it will be called as hot working.
For high precision machining, the machining tolerance can be up to 0.0001-0.001mm, the surface finish Ra can be 0.02-0.1um.
Machining precision is to describe the actual geometrical parameter of the part after machining, such as the size, the form, the position, comparing with the theoretical geometry parameter. The difference from these two parameters is the machining tolerance. The number of the difference show the machining accuracy, the bigger, the lower of the machining precision, the smaller, the higher machining precision.
