Kunshan Lessing Clean Application Materials Co., Ltd. (hereinafter referred to as Lessing Company) is a production-oriented enterprise, which was established in Lujia Town, Kunshan City, Jiangsu Province in 2000. After more than ten years of unremitting efforts, the company successfully listed on the Growth Enterprise Market of Shenzhen Stock Exchange on September 6, 201/kloc-0. The main business of Lessing Company is the research, development, production and sales of high-clean application materials based on high-purity stainless steel. Its main products are the key components of high-clean fluid pipeline system and ultra-high vacuum system, including vacuum chamber, pump, valve, flange, pipeline and pipe fittings, which are mainly used in biomedicine, electronic cleaning and food. , and has become a professional supplier of world-class vacuum equipment manufacturers.
Before 2002, Lessing Company was mainly engaged in the research and development, manufacturing and sales of high-clean application materials for process pollution control in the food field. In 2004, the high-clean application materials in line with ASME BPE standards for process pollution control in biomedical industry were successfully developed and put on the market; In 2006, the applied materials with high cleanliness applied to process pollution control in electronic cleaning industry were successfully developed and put on the market. In addition, Lessing's products are also applied to the research of major national scientific projects, including SSRF (Shanghai Synchrotron Radiation Facility) and the second-level project of National 973 Project "Physical Research of Carbon Nanotube Field Emission Display Devices and Research of Efficient Devices" (project number: 2003CB 14702).
Lessing company has a series of core technologies such as new material technology, precision machining technology, surface treatment technology, clean room technology and ultra-high vacuum technology. It is one of the few manufacturers in the same industry in China with a complete technical system, and it is also at the leading level in the same industry in the world. The technical indexes of the product, such as parent metal purity, machining accuracy, welding process, surface roughness and extreme vacuum, have reached the advanced level at home and abroad, and have been recognized by internationally renowned customers such as Intel, and conform to a series of international standards and specifications such as SEMI, ASME BPE and 3-A, and have been applied in countries such as SSRF (Shanghai Synchrotron Radiation Facility). Lessing Company has successively passed the European Union Pressure Equipment Directive (PED) certification organized by TüV in Germany, the 3-A sanitary standard certification implemented by 3A Company in the United States, and the ISO900 1:2008 quality management system certification implemented by BSI, etc. The products meet the industry standards of american society of mechanical engineers (ASME) BPE products and International Semiconductor Equipment and Materials Association (Semi). At the same time, it is also a member and governing unit of International Pharmaceutical Engineering Association (ISPE), International Semiconductor Equipment and Materials Association (Semi), Clean Technology Branch of China Electronics Society (CCCS) and Jiangsu Vacuum Society.
The company covers an area of * * * 86,666.66 square meters (including Lessing 26,666.6 square meters, Lessing Hefeng Factory 1 10,000 square meters and Bora 50,000 square meters), with a building area of * * * 26,860.1.06 square meters (including Lessing 65,438).
At the same time, the company adheres to the following policies in environmental governance:
1. Make rational use of resources and reduce energy consumption. Such as the improvement of hydraulic water reuse equipment.
2. Implement national standards and meet emission standards. For example, the company uses water treatment equipment to make the wastewater stay in the regulating tank for a long time to ensure the stable effect of subsequent biochemical treatment and not default on sewage charges; Using spray technology, the waste gas produced in the working process is effectively treated to make it meet the emission standard.
3. Develop noise control technologies and equipment such as sound insulation, sound insulation and noise elimination. For example, car engineering, earthquake prevention technology.
4. Green production. Choose flowers and trees suitable for the company's characteristics, purify the air and beautify the environment.
Lessing Company is not only one of the few R&D and manufacturers of high-clean application materials covering three major application fields in China, such as electronic cleaning, biomedicine and food, but also has a number of domestic patents, so it has become a high-tech leading enterprise in clean stainless steel industry, and has been successively rated as an advanced technology enterprise and a high-tech enterprise in Jiangsu Province.
