Productos principales
The company has two fully automatic lost foam casting production lines and 50 sets of various CNC machining equipment. Among them, 80% are high-quality imported equipment, such as Mazak, Dali, and Mori Seiki. It has stable and reliable production capacity, producing over 10,000 tons of lost foam castings annually.
It is the main housing of dual-output transmission gearbox, provides installation support for shafts, bearings and gear sets, realizes power output from two ends. Widely used in agricultural machinery and general reduction transmission equipment, adapting to torque transmission under variable-load working conditions.
It is the air intake sealing component of air compressor, which guides air entering the cylinder and plays the roles of sealing and supporting. It is widely used in piston air compressors, adapting to continuous air intake and pressure cycling working conditions.
It is the main shell of the pump, which forms the fluid flow channel and bears working pressure. It is widely used in water supply and drainage pumps, mud pumps, industrial delivery pumps and hydraulic pumps for construction machinery, adapting to medium conveying, certain pressure and continuous circulation working conditions.
It is the main housing of hydraulic cylinder, which forms the pressure chamber for hydraulic oil. It is widely matched with hydraulic systems of construction machinery and agricultural machinery, converting hydraulic pressure into mechanical thrust to complete lifting, pushing and other actions, adapting to heavy-load and frequent reciprocating working conditions.
It is a key swinging transmission part, which converts rotary motion into reciprocating swing force. It is widely used in agricultural machinery and construction machinery transmission systems, suitable for frequent swing, variable load and impact working conditions.
Multi-groove belt pulley, transmits torque through belt friction, widely used for power transmission in agricultural machinery, air compressors and general mechanical equipment, matches multi-groove belts to drive associated rotating components.
It is the core pressure-bearing cylinder part of large-bore piston air compressor, forming compression chamber together with piston assembly to complete air suction, compression and exhaust work. Widely used in 12 cubic meter piston air compressors, adapting to high-pressure, continuous cyclic compression working conditions.
It is the core rotating power component of air compressor, which realizes gas compression through high-speed rotation. It is widely used in industrial screw air compressors and piston air compressors, adapting to continuous high-speed operation, pressure fluctuation and long-cycle working conditions.
