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.

What is a hydraulic cylinder and how does it function in various applications?

A hydraulic cylinder is a mechanical actuator that converts hydraulic energy into linear force and motion. It plays a critical role in various applications where controlled and powerful linear motion is required. Hydraulic cylinders are commonly used in industries such as construction, manufacturing, agriculture, and transportation. Here's a detailed explanation of what a hydraulic cylinder is and how it functions:

Definition and Components:

- A hydraulic cylinder consists of a cylindrical barrel, a piston, a piston rod, and various seals. The barrel is a hollow tube that houses the piston and allows for fluid flow. The piston divides the cylinder into two chambers: the rod side and the cap side. The piston rod extends from the piston and provides a connection point for external loads. Seals are used to prevent fluid leakage and maintain hydraulic pressure within the cylinder.

Function:

- The function of a hydraulic cylinder is to convert the pressure and flow of hydraulic fluid into linear force and motion. The hydraulic fluid, typically oil, is pressurized and directed into one of the chambers of the cylinder. As the fluid enters the chamber, it applies pressure on the piston, causing it to move in a linear direction. This linear motion of the piston is transferred to the piston rod, creating a pushing or pulling force.

Working Principle:

- The working principle of a hydraulic cylinder is based on Pascal's law, which states that pressure exerted on a fluid in a confined space is transmitted equally in all directions. In a hydraulic cylinder, when hydraulic fluid is pumped into one side of the cylinder, it creates pressure on the piston. The pressure is transmitted through the fluid to the other side of the piston, resulting in a balanced force across the piston and piston rod. This force generates linear motion in the direction determined by the fluid input.

Applications:

- Hydraulic cylinders find extensive use in a wide range of applications due to their ability to generate high forces and precise control of linear motion. Some common applications include:

1. Construction Equipment: Hydraulic cylinders are used in excavators, loaders, bulldozers, and cranes for lifting, pushing, and digging tasks.
