Hydraulic Cylinders Production Technology

Production of high-quality hydraulic cylinders for local machinery is one of the most important tasks for our country. Trade shops do not satisfy the requirements of machines producers in corpore. Many factories-manufacturers of hydraulic equipment ought to produce hydraulic cylinders themselves. These factories often use complex and unwieldy technologies requiring special equipment and tools, ecologically bad areas, etc. For sure, existing tradition has right to be. However depreciation of plant, absence of relevant quality of components and materials, and shortage of specialists do not permit production of hydraulic cylinders of up-to-date technical level.          
Leading foreign companies follow another way: at most they use acquired components, produced by trade shops achieved perfection of their products. Some of the producers hone or burnish tubes to receive high level of accuracy of internal surface; other ones process and chrome-plate rods to assure necessary hardness and aggressive exposures resistance; some of them produce high-accurate pistons and front end bushes; other ones offer different types of ends, etc. Special attention is paid to selection of sealing systems and of support-and-guidance rings, manufacturers of which achieved optimal characteristics of these elements in geometry and materials as well as in in-line arrangement in sealing unit.          
As a result, hydraulic cylinder producer just make mechanical processing only for necessary cutting of cylinder tubes and rods, weld components and complete assembling. After that hydraulic cylinders are tested, packed, and delivered to consumer.  
This approach significantly decreases investments in production, because all the operations can be performed with universal equipment and do not require expensive machines, original tools, and complex rigging. 
Ecologically bad areas and continuous care of materials recovery after chrome-plating of rods are also excluded.
Acquisition of high-quality components is economically sound. Rejection of low-effective and laborious production operations gives possibility to reduce staff or to redirect it for other types of activity. But what is more important, technologies like these assure high quality level of hydraulic cylinders, increase flexibility of production, create possibility of fast expanding of production assortment.
One of the first, National Hydraulic Company Limited started implementation of up-to-date progressive technologies, permitting to organize output of hydraulic cylinders in local plants as fast as possible. They cover small production areas as well as large trade shops.    
Range of offers is broad and flexible: supply of complete processing line, including cutting machines for honed tubes and chromed rods, welding, assembling, and testing equipment. 
Specialists carry out mounting, setting up, and other necessary works, conduct technical training for the workers, organize regular serial supply of all the components: honed or burnished tubes and chromed rods, pistons and front-end bushes, ends and connection threads, seals sets and etc.  
In this case complete closed cycle of hydraulic cylinders production exists. 
If a plant has any equipment meeting the requirements of offered technologies, this plant may acquire only part of technological system as well as to acquire necessary components regularly. 
A client has right to chose any type of supplies.
There are more than 300 companies in Italy that manufacture different types of hydraulic cylinders under similar technological systems. They cover local market as well as foreign markets of hydraulic equipment manufacturers.    
In Russia this approach to hydraulic cylinders manufacturing is just developing.
Plants developing offered technologies earlier may become leaders in this share of the market of machinery production.
