How should we choose a good electric sewing machine?
1. The model of the selected electric sewing machine should be determined based on individual requirements. For general household sewing only, consider purchasing JA and JB type products. If there are high requirements for stitching and patterns, H-type multifunctional electric sewing machine can be considered.
2. Selection should be made from four aspects: listening, watching, researching, and testing
⑴ Listen to the sound emitted by the motor and internal components during idling and loading respectively. The sound should be uniform, stable, and soft, and there should be no irregular or abnormal noise.
⑵ Observe the movement of the needle bar at slow, medium, and high speeds, and ensure that each component moves back and forth evenly and flexibly.
The coordination of each part of the machine should be tightly touched and pressed by hand, without any looseness or jamming during relative movement.
During the trial, thread the thread and sew different patterns of stitches with fabrics of different thicknesses. The stitches should be neat and even, without any jumping or needle skipping, and the adjustments should be flexible, uniform, and convenient
