A user mechanic asked: Regarding the pattern output of the electronic pattern machine, I have encountered such a situation before. Once the factory requested a plastic label (a little hard plastic with the customer's name on it) along a small slot Sew a square, the plastic is 4 mm thick, and use 20-gauge three-strand nylon thread. Two situations occur: First, it is impossible to sew without soaking the thread, and the thread is constantly broken and jumped. Second, it is better to soak the thread with oil. The sewing method is to sew a straight line on the top, then right, down, left, and up (heavy four stitches). There is no problem how to adjust "up, right, down", except that the left side often holds wires, bad wires, jumpers, and disconnects. Until now, it is not clear what the reason is. I have also thought about it, probably because the carriage moves toward the back of the worker, which causes the needle to bend a little when it rises, causing the needle and the hook tip to be too far apart and causing problems. How can I solve it?
The cross stitches are not straight, which is a common problem of electronic pattern machine. If the reverse direction thread comes out of the pinhole, and then rewind and hook the thread 180 degrees, the thread will not come out smoothly. The soft material thread will not be visible when it is buried inside. The hard or thin material will be more obvious. Other problems such as skipped stitches and broken threads There will be more, please ask the mechanics to fine-tune, just try their best to improve, or find other ways to solve it. For the 4 mm plastic sheet mentioned in the question, you can use a small oven (light bulb heating) to bake the plastic soft, take it out and sew, the effect will be very different, or add a needle cooling device, after the needle is cooled, you will receive good results.
