The connection between the fan blade and the main engine of the wind turbine generator can not be realized without the embedded screw sleeve, which is the key product of HNFW Fastening System Technology Corporation.
The blade of the wind turbine weighs more than 20 tons and will rotate in the air for 20 years. The fastener can ensure that it will not break or rust for 20 years.
By 2020, the high-strength embedded inserts for wind turbine blades developed by HNFW have accounted for 70% of the global market share.
Products in the field of wind power：
Embedded screw sleeves of wind power blades, cabin bolts, tower bolts, ground anchor bolts, etc
As a key basic component connecting wind turbine blade and host, each section of tower, fan and ground, high-strength fasteners for wind power are always exposed to severe environments such as typhoon, sand dust, low temperature, high temperature, snow, low concentration salt spray, etc., with a long service life. They have high requirements for product strength, fatigue resistance, corrosion resistance, etc. Product quality is directly related to the safe operation of large wind turbines.
The company's high-strength fasteners for wind power mainly include embedded inserts for wind power blades, machine bolts (blade studs, host bolts, tower bolts), wind power anchor bolt components, etc. The strength grade of insert products is mainly Grade 10, and the strength grades of bolt products are Grade 8.8, 10.9, and 12.9F, covering hundreds of specifications and models.
Fasteners in other industrial fields
The company actively develops high-strength fasteners used in engineering machinery, rail transit, shipbuilding, aviation, automobile, petroleum and other high-end equipment manufacturing industries, mainly including crane slewing support bolts, tunnel segment bolts, ship diesel engine bolts, automobile shock absorber bolts, high-temperature alloy bolts for oil drilling and production devices, etc.
High end precision components
It mainly undertakes the manufacturing of non-standard hardware products, which are used in high-end equipment fields such as aviation, engineering machinery, hydraulic, petroleum, automobile and high-speed railway.
High performance high-temperature alloy screws developed by HNFW have been successfully applied to downhole oil drilling and production and aeroengines.
HNFW is a high-tech enterprise focusing on the R&D and manufacturing of high-strength fasteners. Its fasteners are mainly used in wind power, engineering machinery, rail transit, shipbuilding, oil, electricity, aerospace and other industrial fields. The products are exported to the markets of high-end developed countries such as the United States and Europe[Germany, Denmark, Spain…].
Every year, the company developeda variety of fastener products, some of which are used for ship engines, automobile shock absorbers, and some of which are used for wind turbine operation, oil drilling and production in the harsh environment of typhoon, sand dust, low temperature and high temperature.
