Overview
The SW-737 is a straightforward 3-thread overlock machine for shops that need clean edge finishing without the complexity of a 4-thread setup. It is especially popular with small tailor shops and children’s-wear makers.
Its simple threading and lower price point make it an easy first overlock for a growing workshop — a low-cost way to add professional edge finishing to your output.
If your work is general adult garments or high-volume knitwear, a 4-thread machine is the more capable standard; the 3-thread is the budget-friendly entry.

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.
Is 3-thread enough for garment production?+
For light finishing and children's wear, yes. For general garment production, a 4-thread machine is the standard.
