  • One of the standout features of this sewing machine is the use of two needles. With dual needles, sewers can create parallel rows of stitching simultaneously, giving projects a professional finish that would otherwise require additional time and effort. This function is especially beneficial for decorative stitching or topstitching, allowing for creative designs and efficient work on various sewing projects, such as clothing, quilts, and home decor.


  • At its core, an overlocker uses multiple threads—typically three to five—working in unison to create a secure stitch that finishes the edges of the fabric. The primary purpose of an overlocker is to prevent fraying, which is particularly important in fabrics that tend to unravel, such as knits and some woven materials. By enclosing the raw edges of the fabric, the overlocker effectively protects the integrity of the material and enhances the lifespan of the garment.

  • One of the key advantages of silicone rubber gaskets is their ability to withstand high temperatures. They can maintain their shape and integrity even at temperatures ranging from -100°C to 260°C. This makes them suitable for use in high-temperature environments such as ovens, furnaces, and engines. Additionally, silicone rubber gaskets are also resistant to cold temperatures, making them a good option for applications in refrigeration and air conditioning systems.
