Does anyone know Beijing changkong machinery co., ltd? It's a company in Anxiangli, Chaoyang District. I hope an insider can introduce me, thank you.

At present, the main factory has been moved to the suburbs of Yanqing. This is a brief introduction of the company, which you may have read online. I have friends in this company. If you want to know, you can send your contact information to kanhaku@vip.sina.com.

Established in 1969, Beijing changkong machinery co., ltd. is a national first-class measurement unit of large state-owned enterprises, and has passed the ISO900 1 quality system and stricter quality certification of military products. The aviation military products produced by the company are widely used in military and civil aircraft engines. While ensuring the completion of military tasks, the company relies on the cutting-edge technology and strong economic strength of military enterprises to increase the development of civilian products.

1972, the company developed a rolling riveting machine for military production. Over the past 30 years, we have continuously applied advanced technologies at home and abroad to improve our products, and now we have formed three series 14 varieties of machinery, pneumatic and hydraulic. "Changkong brand" riveting machine meets the different needs of customers with good cost performance. In 2000, "Changkong Brand" riveting machine was exported to Germany, which realized that China riveting machine was exported to western developed countries for the first time and won honor for China's national industry.

1998, the company developed "Changkong" brand tanker. "Changkong" brand lpg and cng series dispensers have won unanimous praise from users for their stable performance, accurate measurement, safety and reliability, simple operation and convenient maintenance. At present, nearly 200 filling stations at home and abroad have used the "Sky" tanker. In addition, entrusted by the State Bureau of Technical Supervision, the company participated in the formulation of national standards for gas dispensers in China, and jointly developed domestic measuring and testing equipment for lpg and cng with the National Institute of Metrology. I believe that the situation that the tanker can't measure and test will soon end.
