Overview

The SW-757 adds a safety stitch to the standard overlock. The result is a seam that both finishes the edge and locks it with a strong chain stitch — ideal for denim, heavy woven fabrics and garments that take real stress.

If you produce jeans, workwear or heavy cotton garments, the 5-thread machine produces a seam quality that a 4-thread machine cannot match. It is the upgrade for workshops whose products are subjected to heavy wear.

For standard knitwear and light garments, the 4-thread 747D is the more economical choice — the 5-thread only earns its place when seam strength is the requirement.

Key Applications

  • Denim jeans and jackets — seams that survive stress points → Garment factory machines
  • Workwear and uniforms — reinforced seams for heavy duty
  • Heavy cotton garments — secure side and crotch seams

What’s Included

  • Machine head
  • Industrial table and stand
  • Servo or clutch motor
  • LED work light
  • Tool kit and manual

Delivered as a complete working unit — no extra parts needed to start production.

Frequently Asked Questions

What's the minimum order quantity?+

1 unit. Order 1–4 machines and we ship by express courier or LCL sea freight — a full container is optional, not a requirement.

Which voltage will I receive?+

Your machine ships configured for your country's mains supply — we confirm the exact voltage with you before shipping. Available options: 220V, 230V, 240V.

Can I get spare parts later?+

Yes — we keep common parts in stock and can include a spare parts pack with your order, so a worn part never stops your production.

What is the difference between 4 and 5 thread?+

A 4-thread machine overcasts the edge. A 5-thread machine adds a second chain-stitch line, making the seam much stronger — better for heavy fabrics.

Do I need a 5-thread machine for normal garments?+

Not usually. For standard knitwear and light woven fabric, a 4-thread machine is enough.

What fabrics benefit most from a 5-thread overlock?+

Denim, workwear and heavy cotton where the seam must not burst under stress.
