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.
