The Juki DDL-5550N-7 sewing machine is designed to deliver high productivity and efficiency in various industries, including garment manufacturing, upholstery, and more. Its advanced features and reliable performance make it an ideal choice for production environments.
Estimating Average Sewing Speed
The average sewing speed of the Juki DDL-5550N-7 varies depending on the type of stitch and fabric used. Typically, it can sew at speeds ranging from 800 to 1,500 stitches per minute (spm) for straight stitches on cotton fabrics. On the other hand, it can reach speeds of up to 2,000 spm for zigzag stitches on polyester fabrics.
“A good rule of thumb is to consider the following average sewing speeds: 800-1,000 spm for straight stitches on cotton fabrics, and 1,500-2,000 spm for zigzag stitches on polyester fabrics.”
Calculating Production Capacity
To estimate the production capacity of the Juki DDL-5550N-7, we can consider an 8-hour workday with a certain number of garments to be produced. Assuming an average sewing speed of 1,000 spm for straight stitches on cotton fabrics, the machine can produce approximately 400 garments per 8 hours. For zigzag stitches on polyester fabrics, with an average speed of 1,750 spm, it can produce around 350 garments per 8 hours.
Production Output Comparison
Here is a comparative table of production output on the same fabric:
| Fabric | Stitch type | Output (garments per hour) | Output (garments per 8 hours)
|————-|————–|—————————–|—————————
| Cotton | Straight | 50 | 400
| Polyester | Zigzag | 30 | 240
This table provides a clear picture of the production output difference between straight and zigzag stitches on cotton and polyester fabrics, respectively.
