The stainless steel sewing machine hook block is one of the important parts of the sewing machine, which is used to control the circulation of the thread and the formation of the stitches. It is usually made of stainless steel, which has the characteristics of high strength, wear resistance and corrosion resistance.

The main function of the stainless steel sewing machine rotary hook block is to interweave the upper thread and the lower thread through the rotary motion to form sewing stitches. It cooperates with the eye of the needle to make the thread form a loop in the eye of the needle to complete the sewing work.

A stainless steel sewing machine hook block usually consists of two parts: a top hook and a bottom hook. The hook-up hook consists of a cylindrical part and a rotating hook part that guides the upper thread from the spool to the eye of the needle. The lower hook is a part with a hook structure, and its function is to guide the lower thread from the bobbin to the eye of the needle, and interweave with the upper thread.

The design and manufacture of the stainless steel sewing machine hook block needs to take into account the different models and uses of the sewing machine, as well as the type and thickness of the sewing thread. Therefore, different sewing machine hook blocks may have different shapes, sizes and configurations.

In short, the stainless steel sewing machine rotary hook block is an important part of the sewing machine, which interweaves the upper thread and the lower thread through rotary motion to form sewing stitches. It has the characteristics of high strength, wear resistance and corrosion resistance, and is suitable for various sewing machine models and uses.
