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.

How does a single-acting hydraulic cylinder contribute to controlled and precise movement?
A single-acting hydraulic cylinder plays a significant role in providing controlled and precise movement in hydraulic systems. Here’s a detailed explanation:
1. Hydraulic Pressure Control: The movement of a single-acting hydraulic cylinder is controlled by regulating the hydraulic pressure supplied to the cylinder’s pressure chamber. By adjusting the pressure, the speed and force of the cylinder’s movement can be controlled. This enables precise control over the extension or retraction of the piston, allowing for controlled and precise movement of the load.
2. Flow Control Valve: Single-acting hydraulic cylinders are often equipped with flow control valves, which further enhance control over the cylinder’s movement. The flow control valve regulates the rate of fluid flow into and out of the cylinder, thereby controlling the speed of the piston’s movement. By adjusting the flow control valve, the movement can be fine-tuned to achieve the desired speed and ensure precise positioning of the load.
3. Cylinder Bore Size and Piston Area: The size of the cylinder bore and the piston area also contribute to controlled and precise movement. A larger cylinder bore and piston area provide a higher force output for a given hydraulic pressure. This allows for finer control over the movement, as smaller changes in pressure result in smaller changes in force. The larger piston area also reduces the effects of internal friction, enabling smoother and more precise movement.
4. Control Systems: Single-acting hydraulic cylinders can be integrated into control systems that provide advanced control and automation capabilities. These control systems can utilize sensors, feedback mechanisms, and programmable logic controllers (PLCs) to precisely control the movement of the cylinder. By incorporating closed-loop control and feedback, the system can continuously monitor and adjust the cylinder’s position, speed, and force, ensuring highly controlled and precise movement.
5. Position Feedback: To achieve precise movement, single-acting hydraulic cylinders can be equipped with position feedback mechanisms, such as linear position sensors or encoders. These sensors provide real-time feedback on the position of the piston, allowing for accurate control and positioning of the load. The position feedback information can be used to adjust the hydraulic pressure or flow rate, ensuring the desired position is achieved with high accuracy.
6. Damping and Cushioning: Single-acting hydraulic cylinders can incorporate damping and cushioning mechanisms to control the deceleration and impact forces at the end of the cylinder stroke. These mechanisms help prevent sudden stops or jerky movements, contributing to smoother and more controlled motion. Damping and cushioning improve the precision of the cylinder’s movement, particularly in applications that require delicate handling or where abrupt stops can cause damage.
7. System Calibration and Tuning: Achieving controlled and precise movement with a single-acting hydraulic cylinder often involves system calibration and tuning. This process involves adjusting the hydraulic parameters, such as pressure, flow rate, or valve settings, to optimize the system’s performance and achieve the desired movement characteristics. Calibration ensures that the hydraulic system operates within the desired range and delivers accurate and repeatable movement.
In summary, a single-acting hydraulic cylinder contributes to controlled and precise movement through hydraulic pressure control, flow control valves, cylinder bore size and piston area, control systems, position feedback, damping and cushioning mechanisms, and system calibration and tuning. These factors work together to provide accurate, smooth, and controlled motion in hydraulic systems, allowing for precise positioning and handling of loads.
