Product Description
BALE WRAPPER
Bale wrapper is a machine that is used to wrap bales of hay or straw. It is typically uses a hydraulic cylinder to lift and rotate the bale. The hydraulic cylinder is a crucial component of the bale wrapper as it provides the necessary force to move and manipulate the bale. It also allows for precise control over the position and rotation of the bale during the wrapping process. The hydraulic cylinder is connected to the lifting mechanism of the bale wrapper, which lifts the bale from the ground and rotates it into the wrapping position. Once the bale is wrapped, the hydraulic cylinder lowers it back down to the ground.
TRACTOR
The tractor is a crucial piece of agricultural machinery, revolutionizing farming operations through its powerful capabilities. Designed for versatility, it can perform a range of tasks, from tilling fields to planting and harvesting crops. The hydraulic cylinder is an integral part of the tractor, connected to the hydraulic system. It converts the tractor's mechanical energy into hydraulic power, essential for manipulating various implements and attachments. The cylinder enables farmers to control these implements with precision and ease, ensuring effective and efficient completion of agricultural operations.
CULTIVATOR
The cultivator is an agricultural equipment which designed to till and cultivate the soil, making it ready for planting. The cultivator breaks up and mixes the soil, removing weeds and rocks, and generally prepares the ground for optimal plant growth. At the heart of the cultivator lies the hydraulic cylinder. This cylinder is connected to the tractor's hydraulic system and converts the tractor's mechanical energy into hydraulic power. The hydraulic cylinder powers the cultivator's various moving parts, such as the tines or blades that till the soil. It allows farmers to control the depth and intensity of tillage, ensuring that the soil is properly prepared for planting.
SPRAYER
The sprayer is used to spray liquid fertilizers, pesticides, or herbicides onto crops in agricultural. The sprayer has a large tank that holds the liquid to be sprayed, and a set of spray nozzles that atomize the liquid and distribute it over the crops. At the heart of the sprayer lies the hydraulic cylinder which is connected to the tractor's hydraulic system and converts the tractor's mechanical energy into hydraulic power. The hydraulic cylinder powers the various moving parts of the sprayer, such as the boom that extends outwards from the tractor and carries the spray nozzles. It allows farmers to control the height and width of spraying, ensuring that the liquid is applied uniformly across the field.

Hydraulic Cylinder Producing Process
Step1: Quality Control on Raw MaterialWe 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 Machiningwe 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, two times in the morning and two 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 WeldingWe 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 one can change it unless the welding manager, and they only have 5% right.
Step4: Quality Control on AssemblingFor 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 two 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 two 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 PaintingWe have our half auto painting line. Right now, we can paint about 1500 cylinders per day, which is about one 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 PackingFor 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 one floor after one 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.
