FAQs
Why did my needle hit the edge of the magnetic embroidery frame during stitching?
This needle strike usually happens when the hoop size selected in the COS embroidery machine software is larger than the 8.7″×8.7″ (220×220 mm) sewing field, or when the design itself exceeds the hoop boundary. Always choose the correct or smaller magnetic hoop size and run a trace test before embroidery to prevent damage.
Which is easier for a new employee to learn: this magnetic hoop or a traditional screw hoop?
For new operators, the Sewtalent magnetic hoop for COS machines has a much shorter learning curve. The snap-on magnetic system reduces manual adjustments and eliminates tension inconsistencies found in screw hoops. Your staff can become productive faster, improving efficiency and accuracy across all embroidery projects.
How effectively does this magnetic embroidery frame grip slick fabrics like silk or nylon?
The magnetic embroidery frame provides evenly distributed pressure that holds slippery materials such as silk, nylon, or stretch fabrics more securely than traditional hoops. It minimizes slippage while protecting delicate surfaces. For the best results, continue using stabilizers appropriate for your COS embroidery machine setup.
What maintenance steps should I follow to keep the magnetic hoop performing well?
Keep the magnetic and metal surfaces clean and dry, wiping them regularly to remove lint or metallic residues. Avoid dropping the frame or exposing magnets to extreme heat. Check bracket screws for tightness before installation on your COS-W1501G or COS-W1501L machine. With proper maintenance, the hoop preserves alignment and consistent fabric grip for years.
