Any electric sewing machine is usually assembled from numerous spare parts, and the quality of the sewing machine parts is crucial for whether the sewing machine can be used normally and achieve the highest work efficiency. Now we provide three ways to identify the advantages and disadvantages of commonly used sewing machine parts, hoping to provide reference for everyone to choose high-quality sewing machine parts.

1: Needle board and feeding teeth

The needle plate and feeding teeth of a general medium speed sewing machine are double row, and the latter half is subjected to greater force. When using a sewing machine with a feeding wrench for feeding, it is easy for the operator to inject needles. If there is an injection phenomenon, the needle plate will collapse; Using high-quality needle plates is less likely to cause the phenomenon of needle plate collapse.

Inspection method: Place a screwdriver into the feeding slot on the needle board and shake it left and right. Carefully observe whether it is deformed under stress. If it is deformed, it is a defective product.

2: Pressing feet

Inspection method: Use pliers to clamp the presser foot and see if the imprint can be removed. Hardened presser feet cannot produce imprints.

3: Needle machine

High speed double section silver white nickel plated needles should be selected. Because most enterprises use high-speed machines, many sewn products are made of new waterproof materials and chemical synthetic fiber materials, requiring the machine needles to withstand high temperatures. Generally, chrome plated machine needles are not suitable, and even if they are usable, the effect is not ideal.
