The products are widely used in high-tech aerospace, electric power, bearing, automobile, motorcycle, metal cutting tools, textile machinery, petroleum geology drilling, building, and high-tech and traditional industries. The factory has advanced management mechanism, strong development and design team, sophisticated technology and equipment, rich production experience, strict quality assurance system and the detection means complete and always adhere to the business principles " quality first, reputation first, service first ". Marketing network is throughout the country.

Our continuous drive friction welding machine series products are mainly Y100-A small friction welding ( welding material diameter of 10 mm below ), Y120-A, Y120-B, Y120-C and friction welding ( welding material diameter of 12 mm below ), Y150-A large friction welding ( welding material diameter of 20 mm below ) and special specifications, non-standard models products. At present our factory has successfully welded various cutter and blank, copper-aluminum transition joint, double metal bearings, valve, ball head pin, universal joint, steering rod, a shaft, shock absorber, turbocharger shaft, S cam shaft, sleeve wrench, screw steel, building of drill pipe, sucker rod, the motor shaft and other parts products.

Yuyao City Biweekly Hardware Machinery Factory take the revitalization of national industry as our own duty, work concentrated on the new product development and research, and will research, develop and promote friction welding machine products in the market to meet customer demand at home and abroad with first-class quality, first-class service, the most competitive price.

The advantages of friction welding:

The welding quality is good and stable. The rejection rate of boiler serpentine pipe and automobile exhaust valve friction welding are decreased to 0.01% from the original flash welding 10% and 1.4%. The welding size is of high precision. The maximum error with full-length of diesel engine combustion chamber is & 177; 0.1%mm. 2) high welding productivity. The productivity of the engine exhaust valve stud automatic friction welding machine can reach 800 ~ 1200 pieces/ h. 3) The production cost is low, because the welding machine power is small, short welding time, so it can save electricity. Friction welding compared with flash butt welding, save energy 80 ~ 90%. In addition the work piece welding margin is small and before welding the work piece does not need special processing and cleaning; sometimes welding edge without removing; without filler material and a protective gas, therefore, the processing cost compared with electric arc welding, can be reduced by about 30%. 4) The welding of dissimilar steel and dissimilar metals. 5) The friction welding machine is easy to realize mechanization and automation and simple operation, easy to master and maintain. The work site is good with no spark arc and harmful gas.

The friction welding, a bonding method, generate heat by the contact surface of the work piece relatively make rotational movement and mutual friction, and the end is thermoplastic, then quickly forging to complete welding.

It is the most common method of friction welding. When welding the two work pieces with circular cross-section, first taking one work piece in the center line as axis and making high-speed rotation, and then another work piece applied axial pressure to the rotation work piece, starting friction heating. When achieved the required friction welding time and friction deformation, namely from joint heating to welding temperature, immediately stop rotate, at the same time, applying axial pressure larger and making welding forging. Usually, all welding process is as long as a few seconds.

Since 1956, friction welding has been developed rapidly at home and abroad, so far, the friction welding machine used in the whole world has arrived by 5000 units, each year product about 1000000000 units.

Our country is the country that has the earliest research and application of the friction welding. In the industrial sector, for example, the electric motor, motor transformer, power plant boiler, automobile and tractor, metal cutting tools, light industrial machinery and oil drilling, has produced various productions by the friction welding, for example, Al-Cu transition joint, copper and stainless steel electric joint, boiler serpentine pipe and valve, exhaust valve and plain journal bearing of the internal-combustion engine, circular knives, textile machine shuttle and oil drill pipe and so on.
