Hangzhou
Threenew Machinery and Electronic Co., LTD, located in
Hangzhou New and High-tech Industrial Development Zone,
was founded in 1991 and firmly confirmed by Science and
Technology Committee of Zhejiang Province.
We mainly manufacture and do research
on Auto-Darkening Welding Helmet (ADWH) and other high-tech
protective products (manufacture license number: XK20-1050035). We
are the first enterprise to produce ADWH within the
mainland of China and have successfully developed infrared-absorbed
filter glass with original creation. The products have
high protective performance and well industrial practicality.
They were listed as the program in Torch Project (1993-1997)
by Science and Technology Committee of China. Our products
become perfect gradually. The control system components
adopt SMD part that is advanced in the international.
We formulate together with Beijing
Labor Insurance Institution the standard of GB/T 3609.1-94
of Auto-Darkening Welding Protecting Eye Mask. Our products
are authenticated to be the Excellent Products by Chinese
Engineering Construction Welding Association.
ADWH is a labor protective product
of high technology. It turns dark once the welding starts.
Consequently, the infrared ray and ultraviolet ray that
do serious disservice to eyes can be filtered.It prevents
occupational disease happening and avoids blinding ignite.
By using it, you can save an auxiliary welder, especially
suitable for using two-handed operation of Gas-Protective
Welding.
Besides ADWH, we also produce Turntable
Cover Welding Helmet (TCWH), Special Welding Helmet
(SWH), Auxiliary Protective Helmet (APH), Grinding Protective
Helmet (GPH) and other all kinds of welding protective
filters.
