How to choose industrial sewing machine correctly

Industrial sewing machineIt is mainly manufactured to meet the requirements of many industrial industries such as clothing, textiles, leather bags, home textiles, and cloth art. As industrial sewing machines can be used in more and more industries, the quality of industrial sewing machines on the market is uneven. Because they look so similar, it is difficult for many people to distinguish. But for professional technicians, it is a piece of cake.

It is understood that as long as we observe more in the process of purchasing industrial sewing machines, we can find many differences. Let us learn together how to choose an industrial sewing machine and how to judge the quality of the machine.

Observe first. In the process of selecting an industrial sewing machine, we should focus on observing whether the machine head is bright, whether there is paint peeling and bruising; whether the electroplating layer of the needle plate, push plate, face plate and upper wheel is intact; whether the pressing plate is straight and painted Whether the surface is cracked or partially discolored; whether the frame is damaged, peeled off, or bent, and whether the gap between the upper and lower shaft and the needle bar of the industrial sewing machine meets the standard requirements, etc. When you see any of the above problems, it means that the quality of the industrial sewing machine is not very good. Second, test the machine. If there is no problem with the industrial sewing machine, you need to test the machine. First try sewing with two layers of thin cloth to check whether the stitches are smooth and even. Then try sewing with a thick material to see if the needle length can reach 3.6mm and whether there is any skipped stitches. In addition, the adjustment should be flexible and convenient.

Secondly, check the industrial sewing machine, that is, remove the belt, raise the presser foot, and gently turn the upper wheel to see if it can work freely; whether the needle can rise and fall in the middle of the needle plate hole. At the same time, in this process, we have to listen to the sound of the motor and internal components when idling and loading. Generally, the sound produced by a normal industrial sewing machine is uniform, stable and soft. Irregular noise and abnormal sound are not allowed. Of course, according to various problems in the actual use of industrial sewing machines, more specific tests can also be carried out in the presence of the sewing machine operators.
