NY-4-434D 2 needle 4 thread overlock machine
The NY-4-434D is a high-performance 2 needle 4 thread overlock machine from Zhejiang Nanyuan Sewing Equipment Co., Ltd. - part of the NY professional series built for workshops, tailoring shops, and serious home sewists who demand industrial-grade reliability in a compact form factor. The machine body is constructed from high-quality cast iron and aluminum alloy, delivering the structural stability of heavy machinery at an ultra-light 8.5 kg net weight. A 122W motor drives 8 distinct stitch patterns at up to 1,300 stitches per minute, while the user-selectable blue or white control panel lets buyers match their workspace aesthetic. The NY-4-434D is the bridge between consumer sergers and full industrial overlockers - portable enough for home use, powerful enough for daily professional output.
Key Selling Points
Unlike basic overlockers limited to a single stitch style, the NY-4-434D offers 8 stitch variations. Users can select the optimal stitch for edge finishing, rolled hemming, seam overcasting, and decorative edging without retooling or accessory changes.
The cast iron + aluminum alloy frame provides the vibration dampening of a heavy industrial machine while keeping net weight to just 8.5 kg (10 kg gross with packaging). This is the lightest metal-body 4-thread overlocker in the Nanyuan lineup.
Top speed of 1,300 stitches per minute with a user-adjustable stitch length of 1–4 mm and a 5 mm presser foot lift. Dial in precision for silk or speed for denim - the machine adapts instantly.
A purpose-built 122W motor delivers consistent torque through thick multi-layer seams up to 3.5 mm total material thickness. No power drop-off when transitioning from lightweight linen to stacked denim hems.
Available with a blue or white control panel to match your workspace or brand identity. A small detail that matters to retail buyers and workshop owners who value visual consistency.
At just 260×260×300 mm (packed: 300×290×302 mm), the NY-4-434D occupies minimal desk space. Ideal for urban tailoring shops, apartment sewing rooms, and multi-machine production benches.

| Home-Based Sewing Businesses | Small-batch producers of custom clothing, baby wear, and home textiles get industrial finish quality without the floor-space cost of a full-size industrial overlocker. The 8.5 kg weight allows easy setup and teardown. |
| DIY Enthusiasts & Crafting Hobbyists | Users who sew regularly at home and want to graduate from a basic machine to a metal-body 4-thread overlocker. 8 stitch patterns provide room to grow skills from simple hemming to decorative edge treatments. |

FAQ
Q: What distinguishes the NY-4-434D from other 4-thread overlockers?
A: The NY-4-434D combines a cast iron + aluminum alloy body with just 8.5 kg net weight - offering industrial-grade vibration control in a portable form factor. It also features 8 stitch patterns versus the typical 1–2 on competing machines, and offers selectable blue or white control panels.
Q: How do I thread this machine correctly?
A: Thread in sequence through all thread guides, tension discs, and needle eyes. The lower thread bobbin should be placed clockwise into the bobbin case. A detailed threading diagram is included in the user manual, and the control panel markings guide each step.
Q: Can I adjust the stitch length?
A: Yes. The stitch length is adjustable from 1 mm to 4 mm using the dedicated control dial. Shorter lengths suit delicate fabrics and fine finishing; longer lengths work well for denim, canvas, and decorative edge effects.
Q: What is the maximum fabric thickness it can handle?
A: The NY-4-434D handles materials up to 3.5 mm in total thickness with a presser foot lift of 5 mm. This covers linen, elastic fabrics, denim, and knitwear. For layered seams exceeding 3.5 mm, reduce stitch speed and use the manual handwheel for controlled punching.
Q: What is included in the package?
A: Each unit includes the machine body, 122W motor, standard accessories (needles, bobbins, threading tools), user manual, and warranty card. An optional accessory kit with additional presser feet is available.
Q: Can the panel color be chosen at order?
A: Yes. The NY-4-434D is available with either a blue or white control panel. Specify your color preference when placing your wholesale or sample order. The machine body itself remains a uniform professional finish.
