Cylinder End

Cylinder head, also known as cylinder head, is mainly used in construction machinery industry and wind power generation industry. Our company produces a variety of oil cylinder head products in these two industries, and we have passed the ISO 9001 quality system certification in 2015 and are qualified to produce related products.

After years of processing experience, our Baohua company can manufacture molds according to customer's needs, and mass produce cylinder heads after forging. After repeated pre-forging by heating and die forging, the forging has high forging ratio and good durability.

Product Details

Cylinder head on construction machinery refers to the head of hydraulic cylinder, also known as hydraulic cylinder head. It is the key component of the hydraulic cylinder, which is used to transmit and control the movement of the hydraulic cylinder. Hydraulic cylinder heads are usually made of high-strength materials to withstand high pressure and heavy load working environment. In construction machinery, hydraulic cylinder head is often used in excavators, forklifts, bulldozers and other large machinery to control and adjust the action of machinery.

Cylinder Heads

The cylinder heads produced by our company are mainly used in construction machinery industry and wind power generation industry. Raw materials are purchased from round steel with recognized quality at home and abroad. We can forge the corresponding model of dies and hammers according to customers' requirements, thus improving production efficiency and saving time. At present, we have many types of materials such as: 42CrMo, 45#, 35CrMo, 4140, 4130, etc.

Our Baohua Company was founded in 1969. After three generations' hard work, it now covers an area of 50,000 ㎡ and has a building area of 25,000 ㎡. There are 260 employees and 46 engineering technicians. The annual output of forgings is 30,000 tons. Mainly in the automobile, hydraulic machinery, wind power generation, petroleum machinery parts, construction machinery, mining, metallurgy, shipbuilding machinery and other industries to produce related accessories. The products sold are oriented at home and abroad. The company has its own technology research and development organization "Zhangqiu Baohua Forging Technology Development Center".

The company's main management, technical personnel and key equipment operators have more than 15 years of working experience in the same industry.

And since 2001, the company has successively passed ISO9001, ISO14001 and APIQ1, and obtained the "Special Equipment Manufacturing License".


At present, our forging equipment in Baohua Company mainly includes: five tons and three tons of free forging hammers, 2500 tons, 1000 tons and 600 tons of friction presses, six large plywood hammers and various types of air hammers; There are more than 60 sets of machining equipment, including CA5116E*1015 vertical lathe, CW61100B and CW50 lathe. There are 2 sets of well-type and trolley-type electric furnaces for heat treatment. There are two tempering furnaces, which can complete product normalizing, annealing, tempering and other technological treatments. Equipped with a nationally recognized physical and chemical laboratory, the main testing equipment is a spectrometer imported from Germany with a value of nearly 500,000 yuan; Brinell hardness tester imported from the United States with a value of 120 thousand yuan can carry out ultrasonic nondestructive testing and mechanical performance test.
