There are two end forming machines that the annual output of end forming glass tubes is 4000T.

The glass tubes production line for fluorescent lamp was built in 1996. The production line introduced the key equipment and manufacturing technology of NEG. So the production line runs with high starting point. The automatic proportioning system is fully closed and weigh automatically, which can be high precision and no pollution. The furnace adopts international advance technology which is more efficient, more environmental protection and saves more energy. Glass tube forming technology is from Danner technology.
