Frequent breakage of sewing machine needles is a common problem that can be caused by a variety of reasons. Here are some common reasons and their solutions:

1. Improper needle size selection

Cause: The needle size used does not match the fabric thickness.

Solution: Choose the appropriate needle size according to the thickness of the fabric. Use thin needles (such as No. 9 or No. 11) for thin fabrics and thick needles (such as No. 14 or No. 16) for thick fabrics.

2. Improper needle installation

Cause: The needle is not installed correctly or is not fully inserted into the needle bar.

Solution: Make sure that the needle is fully inserted into the needle bar and the flat part of the needle is facing the correct direction (usually toward the back).

3. Bent or blunt needles

Cause: The needle bends or becomes blunt during use.

Solution: Check the condition of the needle regularly and replace bent or blunt needles in time.

4. Sewing too fast

Cause: High-speed sewing may cause the needle to overheat or be subjected to excessive force.

Solution: Reduce the sewing speed appropriately, especially when sewing thick materials or complex fabrics.

5. Improper fabric handling

Cause: The fabric is too thick or too hard, causing excessive force on the needle.

Solution: Use needles suitable for thick materials (such as leather needles or denim needles), and ensure that the fabric is flat and wrinkle-free.

6. Improper presser foot pressure

Cause: The presser foot pressure is too high or too low, affecting the normal operation of the needle.

Solution: Adjust the presser foot pressure to make it suitable for the fabric currently being sewn.

7. Improper thread tension

Cause: The thread tension is too high or too low, causing uneven force on the needle.

Solution: Adjust the thread tension to make it suitable for the fabric and thread currently being sewn.

8. Internal problems of the sewing machine

Cause: Wear or failure of internal parts of the sewing machine.

Solution: Regularly maintain and clean the sewing machine, and ask professionals to overhaul it when necessary.

9. Improper use of thread

Cause: The thread used is too thick or of poor quality, causing excessive force on the needle.

Solution: Choose a thread suitable for the needle size and fabric, and ensure good thread quality.

10. Needle plate or bobbin case problem

Reason: The needle plate hole or bobbin case has burrs or is damaged, causing the needle to collide.

Solution: Check the needle plate and bobbin case, and replace or repair them if necessary.

11. The sewing machine needle does not match the fabric

Reason: The type of needle used is not suitable for the fabric currently being sewn.

Solution: Choose the right needle according to the fabric type, such as general needles for ordinary fabrics, elastic needles for elastic fabrics, and leather needles for leather.

Summary

Frequent breakage of sewing machine needles may be caused by a variety of reasons, including improper needle size selection, incorrect needle installation, bent or blunt needles, too fast sewing speed, improper fabric handling, improper presser foot pressure, improper thread tension, internal problems of the sewing machine, improper use of thread, needle plate or bobbin case problems, and mismatch between needle and fabric. By checking and adjusting these factors, needle breakage can be effectively reduced to ensure smooth sewing work.
