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.

How do hydraulic cylinders ensure smooth and consistent movement in heavy machinery?
Hydraulic cylinders play a vital role in ensuring smooth and consistent movement in heavy machinery. Their design and operation allow for precise control over the motion of heavy loads, resulting in efficient and reliable performance. Here’s a detailed explanation of how hydraulic cylinders contribute to smooth and consistent movement in heavy machinery:
1. Hydraulic Fluid and Pressure:
– Hydraulic cylinders operate by utilizing hydraulic fluid, typically oil, to transmit force and motion. The fluid is pressurized by a hydraulic pump, creating a force that acts on the piston inside the cylinder. The pressure of the hydraulic fluid can be precisely controlled, allowing for smooth and gradual movement of heavy machinery. The fluid’s incompressibility ensures that the force is evenly distributed, resulting in consistent and predictable motion.
2. Piston and Cylinder Design:
– Hydraulic cylinders are designed with precision to ensure smooth movement. The piston and cylinder bore are machined to tight tolerances, reducing friction and minimizing internal leakage. This precise fit between the piston and cylinder walls helps maintain consistent motion without jerks or sudden changes in speed. Additionally, the use of high-quality seals and lubrication further enhances the smooth operation of the cylinder.
3. Control Valves and Flow Control:
– Hydraulic systems incorporate control valves that regulate the flow of hydraulic fluid into and out of the cylinder. These valves allow for precise control over the speed and direction of the cylinder’s movement. By adjusting the flow rate, operators can achieve smooth and controlled motion of heavy machinery, avoiding sudden starts or stops. Flow control valves also enable speed adjustment, ensuring consistent movement even under varying loads or operating conditions.
4. Cushioning and Damping:
– Hydraulic cylinders can be equipped with cushioning mechanisms to absorb shock and minimize impacts during the movement of heavy machinery. Cushioning is achieved by incorporating specialized valves or adjustable orifices in the cylinder, which restrict the flow of hydraulic fluid near the end of the stroke. This gradual deceleration helps prevent sudden jolts or vibrations, maintaining smooth and consistent movement while reducing stress on the machinery and its components.
5. Load Balancing:
– Hydraulic cylinders can be designed and arranged in a system to balance the load and distribute forces evenly. By utilizing multiple cylinders in parallel or series configurations, heavy machinery can achieve balanced movement, preventing uneven stress and ensuring smooth operation. Load balancing also helps minimize the risk of component failure and enhances the overall stability and longevity of the machinery.
6. Feedback and Control Systems:
– Advanced hydraulic systems incorporate feedback sensors and control systems to monitor and adjust the movement of heavy machinery. These sensors provide real-time information about the position, speed, and force exerted by the hydraulic cylinders. The control system processes this data and adjusts the flow of hydraulic fluid accordingly to maintain smooth and consistent movement. By continuously monitoring and regulating the cylinder’s operation, feedback and control systems contribute to precise and reliable motion control.
7. Maintenance and Servicing:
– Regular maintenance and servicing of hydraulic cylinders are essential to ensure their smooth and consistent movement in heavy machinery. Proper lubrication, inspection of seals, and replacement of worn-out components help maintain optimal performance. Preventive maintenance practices, such as filter replacements and fluid analysis, also contribute to the longevity and reliability of hydraulic systems, ensuring consistent movement over time.
In summary, hydraulic cylinders ensure smooth and consistent movement in heavy machinery through the use of hydraulic fluid and pressure, precise piston and cylinder design, control valves and flow control, cushioning and damping mechanisms, load balancing, feedback and control systems, and regular maintenance and servicing. By leveraging these features, hydraulic cylinders provide the necessary force and control to handle heavy loads while maintaining precise and reliable motion, enhancing the overall performance and productivity of heavy machinery in various industrial applications.
