How to choose a Heavy Duty Pattern Sewing Machine?
Dec 17, 2020

Heavy Duty Pattern Sewing Machine should be selected from four aspects: listening, watching, checking and testing:

⑴ When idling or with a load, listen to the sound of the motor and internal parts when running. The sound should be uniform, stable and soft, and there should be no irregular noises and abnormal sounds.

⑵ See the upper movement of the needle bar at low speed, medium speed and high speed respectively, and the movement of each part should be uniform and flexible.

(3) The fit of each part of the machine should be tightly touched and pressed by the relative moving parts, and there should be no looseness or movement jamming.

⑷ Put on the thread during the trial, try to sew the stitches of different patterns with fabrics of different thicknesses. The stitches should be neat and uniform, without thread jumpers and stitches, and the adjustment should be flexible, uniform and convenient.
