Our advantage:
1.Automatic Production line for Raw Glass Tube,High Quality of Raw Glass Tube and Advanced Testing Machine. Quarz Sand Pufity is over 99.2%,others only 98.2-98.4% which is more easier to broken.
Good Straightness and Ovality AccurElectrical ContrTimer & Counter ol System acy.No stone or knob.
2.Cleaning the inner tube in preparation for the process of coating later on.Using perified water not city water.3.Tube opening part is smooth, no sunken part or bubbles.
4.We adopt automatic round vacuum device instead of individual vacuum device. Vacuum time is more than one hour. Vaccum: >3x10-3 Pa
5.Absorption Rate:≥0.92 (AM1.5) ; Emission Rate:≤0.06 (80ºC±5ºC);Stagnation Temperature: Above 240ºC6.Coating Time: 1 Hour7.Round tip makes it not easy to get broken.
8.Connecting extra pipe method guarantees the thickness of tMachine Hardware ube bottome, not easy to get broken.
9.Advanced testing equipment from Germany and Japan.We: 1000-1200 pcs out of 1500 pcs are qualified.
Others: 1500 pcs out of 1500 pcs are qualified.10.Fast Delivery: 7 days for 5*40HQ; 10 days for 10*40HQ11.Temperature increases fast from 60-100ºC.FAQ:
1. What is your production capacity per year?
--Production capacity could reach 10 million pcs per year.
2. Do you produce the high borosilicate glass tubes all by yourself?
--Yes, we have 2 furnaces in our factory and over 20 coating lines. We could assure the stability of quality from the glass tubes to solar vacuum tubes.
3. How about the guarantee?
--Five years guarantee and 15 years' lifespan.
4. Is OEM available?
--Yes, we could help you design the logo and print logo on tubes and packages.
