Hydraulic Cylinder Producing Process
Step1: Quality Control on Raw Material
We have our own lab in factory, inspect the raw material and do the test. For every batch of material we received, we will ask supplier provide their certificate, and then cut them to do the test again to see if the results match the certification. Also, every batch we received, we will cut them into pieces to check the air bubbles. Once they are all qualified, we will accept it, and all detail information will be recording in our ERP system. We will also pay lot of attention on the salt spray test for chrome rod. Every month, we will cut the material, put them into test machine to see if it reach the requirement. All the result will be recorded at our QC department. If customer need, we can provide it.
Step2: Quality Control on Machining
we start doing components machining from 1988 with 36 years experience now and insist doing 100% inspection. We spend lots of money, invest on auto robots and machines. Now half of the producing line is by robot so that we can ensure our quality be stable good. For every part of the cylinder, we do 3 times inspecting. Firstly, workers will do self inspection. Secondly, we have tour-hour inspection checking the products, 2 times in the morning and 2 times in the afternoon, make sure that every step is good. After the products are all completed, we will do 100% inspection. For thread, for the tolerance, everything, we need double check. Also, we have specific warehouse just for the measuring tools. Every inspector have their own measuring tool and we will check the measuring tools regularly to make sure they are all in good condition, so that the measuring results will be convincing.
Step3: Quality Control on Welding
We are qualified to AWS certification, which is very popular in North American market. First, for the visual test, we will make sure that every components are welded good, look beautiful. And the second, we need to check the penetration. We have more than 15 years experience, we do know what kind of designing angle can make the cylinder welding strong. Once we finish the first article, we will cut it and analyse the welding to see if it is fulfill the groove. And then do the radiographic testing to make sure there is no gap inside. What’s more, we will do the ultrasonic test to check the program for the robot. Now 80% of welding is doing by robot. Once the program confirmed, no 1 can change it unless the welding manager, and they only have 5% right.
Step4: Quality Control on Assembling
For assembling, we have some difference with others. The brand we uses for seals are all those famous brand like Aston, Parker, Hallite. The cylinder we give to our customer has 2 years warranty. For our company, we engrave our part number and manufacturing date for the quality warranty. So no matter for seals or any others, as long as they are parts of cylinder, if it is under 2 years, we will take responsibility for them. And we will do the test for every cylinder like for pressure after we finish assembling.
Step5: Quality Control on Painting
We have our half auto painting line. Right now, we can paint about 1500 cylinders per day, which is about 1 container. Before we do the painting, we will do the wash first and for every cylinder, we will test for hardness, thickness and adhesion to make sure the painting are all good, which will be recorded into OQC report, print out and stick on the box, ship to you with your products.
Step6: Hydraulic Cylinder Packing
For every cylinder, we have the stick to show the detail information like bore size, stroke and working pressure. And we will use individual plastic bag packing. If customer need, we can also use individual carton box packing. We will fasten 1 floor after 1 floor with plat, so customer can only cut what they need and other layer will still be fasten. Moreover, there will be plywood pallet or plywood box for customer choosing. We will also send the loading picture to customer after we ship them to make sure everything is well loaded in China.

Can you explain the role and significance of hydraulic cylinders in machinery?
Hydraulic cylinders play a crucial role in machinery across various industries. They are essential components that provide controlled and powerful linear motion, enabling the operation of heavy equipment and facilitating numerous tasks. The role and significance of hydraulic cylinders in machinery can be explained in detail as follows:
Role of Hydraulic Cylinders:
– Conversion of Hydraulic Energy: Hydraulic cylinders convert hydraulic energy, typically in the form of pressurized hydraulic fluid, into linear force and motion. This conversion allows machinery to perform tasks such as lifting, pushing, pulling, clamping, tilting, and controlling various mechanisms.
– Generation of Linear Motion: Hydraulic cylinders generate linear motion by utilizing the principles of Pascal’s law. When hydraulic fluid is directed into one side of the cylinder, it applies pressure on the piston, resulting in linear movement of the piston and the attached piston rod. This linear motion can be used to actuate other components within the machinery or directly perform the required task.
– Force Generation: Hydraulic cylinders are capable of generating high forces due to the hydraulic pressure applied to the piston. The force output of a hydraulic cylinder depends on the surface area of the piston and the pressure of the hydraulic fluid. This force allows machinery to exert significant power for lifting heavy loads, applying pressure, or overcoming resistance.
– Precise Control: Hydraulic cylinders offer precise control over the linear motion and force exerted. By regulating the flow of hydraulic fluid, the speed and direction of the cylinder’s movement can be accurately adjusted. This level of control is crucial in machinery that requires precise positioning, delicate movements, or synchronization of multiple cylinders.
– Integration with Hydraulic Systems: Hydraulic cylinders are integral parts of hydraulic systems used in machinery. They work in conjunction with hydraulic pumps, valves, and actuators to create a complete hydraulic circuit. This integration allows for efficient power transmission, control, and coordination of various machine functions.
