All types of machines have some common characteristics: semi-dry head, lightweight, and direct drive motor. Utilizing the different functions of these machines can greatly improve the sewing efficiency of underwear. Having each machine do less also effectively simplifies the process.

Mainly used to provide unique appearance and elasticity for stitching, with 14 different types of stitches installed and able to store up to 99 patterns. You can observe that the elastic parts of underwear are mostly stitched in curves, which maintains the elasticity of the fabric while ensuring sturdiness.

The zigzag machine is also needed in the final steps of underwear production, such as for the button area.

An ultra high-speed machine, capable of 3000-3200 stitches per minute, greatly improving sewing efficiency. Mainly used for extra reinforcement, such as connections between shoulder straps and cups, connections between bottom elastic and cups, etc.

This machine considers the precision needs of underwear. With 5000RPM sewing speed, it also has a trimmer and thread wiper under the bed to adjust subtle differences during production.

Mainly used for securing shoulder straps and underwires, as these two parts are parallel and symmetric, this machine can effectively reduce the time for parallel lockstitching and make both sides more symmetrical.

The presser foot of the machine can control very subtle variables, reducing pressure on the fabric, so it is very suitable for fuzzy fabrics or those with elasticity.

The machine's operation platform has some width, so even if there are some width variations in the stitching, such as some inconsistent widths on underwires, or some shoulder straps with uneven width, it can adjust very well to keep the stitches uniform.

A machine designed specifically for shoulder strap production, capable of completing the processes of strap cutting, slider insertion, edge stitching, O-ring insertion (for connection between strap and underwear, some underwear omit this ring) in one machine with very high efficiency, basically finishing a strap in five seconds.
