Founded in 1995, with registration capital of 60 Million RMB, Shandong Wantong Hydraulic Co., Ltd is specialized in hydraulic products Design, R&D and Manufacturing the same.

We mainly produce Hydraulic Cylinders for the Trucks, Coal Mining Industry, Metal Forming Industry Ship Industry, Oil Rigs and Ocean Engineering. Also we can design and manufacture various special purpose hydraulic cylinders according to customer design and requirements as agriculture industry, 6 DOF platform, machine tools, etc.

Our annual capacity is 200,000 pcs of cylinders which makes our company an important production base for Hydraulic Cylinders in China.

Our factory complex covers floor area of 180,000 square meters (193,000 square feet), and has more than 500 employees. We have solid and advanced production equipment including cold drawing, heat treatment, and surface treatment, hard-chroming with electro-plating, testing machines and various CNC machines, makes total of 700 sets of machines.

Since our total production going through in same factory premises which guarantees best quality and short lead time. All the products have passed validation of ISO/TS16949, CCRI, CCS, and DNV AND ABS, API,etc.

R&D AND TEST CAPACITY

We have an excellent R&D team, and we are using advanced design software to make our products and make them more precise. To ensure every cylinder qualified, we have built our large size Digital Hydraulic Testing platform controlled by PLC and our quality assurance team will test and record each quality and test function requirement to guarantee the products we supply to our customers are the best.

THE PROVIDER

Our dedicated and competent team of design engineers equipped with their extensive field experience in manufacturing, production and on site know-how is equally capable in delivering value added system and engineering support and after sales services to our valued customer.

1.Raw materials entering the factory, 27SiMn, 40CrMo, ST52, 45# steel tubes or bars for choice

2.Do the pre-treatment including pickling, phosphating and saponification, and then cold-draw the seamless steel tubes.

3.Put the steel tubes into the tempering furnace to do the stress relief annealing in convenience of the subsequent the processing.

4.Multi-roll straightening machine, with 10 straightening points, achieves the automatic rolling straighten, improving the efficiency greatly

5.Heat treatment to obtain workpieces with different properties by changing their internal microstructure or surface chemical composition.

6.Cylindrical degree can be controlled within 0.03mm and the surface roughness is up to 0.4 by honing with range:φ40mm-φ450mm and longest length: 12000mm

7.Machining processes to obtain high precision parts with complex shapes strictly according to the detailed drawings

8.Electroplating production processfulfillsthe functional and ornamental requirements for coating workpieces of different dimensions according to specific application requirements.

9.Cleaning all the parts by automatic cleaning machine in the special solution and under specific temperature control effectively

10.All the parts are assembledinto complete cylinders according to the strict assemblyinstructions by skillful workers in dust-free workshop.

11.Do proof pressure and performance tests to check whether the cylinders can operate smoothly and stably under the specified pressurewith no leakage and deformation

12.Do the painting including high quality primer and topcoat to obtain beautiful appearanceand protect the cylinders against the anticorrosion.

13.The fatigue test bench, that is, the heat exchanger fatigue test bench, is an instrument used for durability test, which can automatically fulfil the cyclic actions of fatigue test, and make the judgement and count of test results, under the coordination of control system, the data acquisition system and other auxiliary measurement control devices.

The hydraulic cylinders produced by our company, through the test on the durability test bench, have fully extended and retracted 30,000 times, and the operations are stable with no leakage and deformation.

14.Wooden palletor boxes packing with plastic films wrapped on the surface, suitable for long-time sea transport
