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.

How does a boom cylinder contribute to precise boom control and positioning?

A boom cylinder plays a crucial role in enabling precise boom control and positioning in heavy machinery. Here’s a detailed explanation of how a boom cylinder contributes to this:

  • Linear Force Generation: A boom cylinder is a hydraulic actuator that generates linear force. When hydraulic fluid is supplied under pressure to one side of the cylinder, it pushes the piston, extending the cylinder and resulting in the extension of the boom. By controlling the flow rate and pressure of the hydraulic fluid, operators can precisely control the speed and force of the boom’s movement, allowing for accurate positioning and control.
  • Boom Stability and Rigidity: Boom cylinders provide stability and rigidity to the boom structure. As the cylinder extends, it locks the boom in position, preventing unwanted movement or sagging. This stability is crucial when performing tasks that require precise positioning, such as lifting or placing heavy loads, manipulating attachments, or performing delicate operations. The boom cylinder’s ability to maintain the boom’s position enhances overall control and accuracy.
  • Controlled Retraction: Boom cylinders not only facilitate boom extension but also controlled retraction. By supplying hydraulic fluid under pressure to the other side of the cylinder, the piston retracts, allowing for controlled and precise boom retraction. This controlled retraction is essential for tasks that require accurate placement or lowering of loads, adjusting attachment positions, or retracting the boom to a desired resting position.
  • Hydraulic Control System: Boom cylinders are part of a hydraulic control system that enables precise boom control and positioning. The hydraulic control system regulates the flow and pressure of hydraulic fluid entering and exiting the cylinder, allowing operators to adjust the speed, force, and direction of the boom’s movement. Fine adjustments can be made to achieve the desired positioning, ensuring precise control over the boom’s actions.
  • Integration with Other Components: Boom cylinders are integrated with other components, such as hydraulic valves, pumps, and sensors, to facilitate precise boom control and positioning. Hydraulic valves control the direction and flow of hydraulic fluid, while pumps provide the necessary pressure. Sensors can provide feedback on the boom’s position, load conditions, or operating parameters, enabling operators to make real-time adjustments for optimal control and positioning.

By combining linear force generation, boom stability, controlled retraction, hydraulic control systems, and integration with other components, a boom cylinder contributes to precise boom control and positioning. This precision allows operators to execute tasks accurately, maintain stability, and achieve the desired positioning for various operations in industries such as construction, mining, material handling, and more.
