Key Features
1. Overlock Stitch Elastic Attachment Uses an overlock stitch to attach the elastic band to the waistband — providing strong, stretch-resistant seam coverage that encases the elastic edge cleanly. The overlock stitch is the industry-standard method for elastic band attachment in men’s underwear production, delivering both functional durability and a clean finished appearance.
2. DC Motor Control Electronic DC motor drive provides precise, regulated sewing speed with smoother acceleration and more consistent stitch formation than conventional AC motor machines — improving stitch quality at high speed and reducing energy consumption across a full production shift.
3. Touchscreen Display Intuitive touchscreen control panel for all machine parameters — sewing speed, stitch settings, production count, and cycle configuration. Reduces setup time and simplifies operation for all operator skill levels without mechanical adjustment.
4. Automatic Thread Trimmer Thread is cut automatically at the end of every sewing cycle — eliminating manual trimming between pieces, maintaining a clean work area, and saving several seconds per piece across a high-volume production run.
5. Automatic Foot Lifter The presser foot raises automatically at the end of each cycle, reducing operator hand movements between garments and speeding up loading — contributing to higher sustained output over a full shift.
6. 35–70 cm Sewing Range The broadest waistband sewing range in SAKGO’s men’s underwear series — covering small through to extra-large waistband sizes, and extending into sportswear and activewear waistband dimensions, all without mechanical adjustment.
7. 180–240 Pieces Per Hour Consistent high-output production rate maintained across full shifts — meeting the throughput demands of large-scale men’s underwear and sportswear production lines.
8. Low Air Pressure Requirement (>0.4 Bar) Operates at a low minimum air pressure — suitable for production environments with lighter compressed air infrastructure or where air supply is shared across many machines on the same line.
9. Optional Clamp Bar Stacker An optional clamp bar stacker automates output stacking after each cycle — reducing operator handling and enabling one operator to manage multiple SK-1125 machines simultaneously with minimal physical intervention.
10. CE & ROHS Certified Meets European CE and ROHS certification standards — suitable for export-oriented factories supplying global men’s underwear and apparel brands.

Frequently Asked Questions
The SK-1125 performs elastic band attaching using overlock stitch — it sews the elastic band onto the waistband of the garment using an overlock seam that encases the elastic edge and provides stretch-resistant coverage. This is the elastic attachment step in waistband construction — the SK-1124 top-stitching machine then completes the waistband finishing in the next operation.
These two machines perform sequential operations on the same waistband. The SK-1125 attaches the elastic band to the waistband using overlock stitch — this is the first step. The SK-1124 then applies the top-stitch along the waistband edge to finish and secure it — this is the second step. Both are needed for complete waistband construction in men's underwear production.
Both machines attach elastic to waistbands, but they use different methods. The SK-1018 is an elastic attaching machine for the full waistband assembly operation with automatic edge alignment and waist tightening. The SK-1125 specifically uses an overlock stitch method for elastic attachment and covers a wider sewing range (35–70 cm vs 35–60 cm). The right choice depends on the specific elastic attaching method required for your garment construction.
Overlock stitch provides strong seam coverage that encases the elastic edge cleanly, prevents fraying, and stretches with the elastic during wearing and washing without breaking or distorting. It is the industry-standard stitch type for elastic band attachment in men's underwear because it delivers both functional durability and a neat finished appearance on the inside of the garment.
The machine covers a sewing range of 35–70 cm — the broadest range in SAKGO's men's underwear automation series. This accommodates standard underwear waistband sizes from small to extra-large, as well as larger waistbands for sportswear and activewear.
DC motor control provides electronically regulated sewing speed — smoother acceleration, more consistent stitch formation at high speed, and lower energy consumption compared to conventional AC motor machines. This improves stitch quality consistency across a full production shift, particularly when running at the machine's upper speed range.
