**High-Speed Sewing Performance (2800 Stitches/Min):**
With a 3.0mm stitch length, this machine achieves high-speed sewing thanks to its direct-drive servo motor. Compared to traditional models, it reduces mechanical operation time by about 28%, significantly improving productivity.
**Testing Conditions:**
- Stitching pattern: Rectangle (300x200mm)
- Stitch: 3.0mm
- Sewing speed: 2700 (traditional model) vs. 2800 (MLK-342H)
**Strong Penetration Force:**
Equipped with a 750W servo motor, the MLK-311H provides stronger penetration force than traditional machines, even at low speeds. This makes it ideal for thick materials.
**Low Power Consumption:**
Compared to similar models on the market, the MLK-311H uses up to 15% less power, making it one of the most energy-efficient computerized sewing machines available.
**Precise Cloth Positioning:**
The double-step clamp allows for accurate positioning of fabric, reducing errors and saving cycle time.
**Easy Pattern Change:**
Changing the clamp or feed plate is quick and simple—just remove 4 screws and reposition.
**Large Memory Capacity:**
Supports up to 999 patterns and 500,000 stitches. With an SD card and USB interface, data can be easily transferred between machines or computers.
**User-Friendly Touch Panel:**
The LCD touch panel allows for easy navigation, quick access to frequently used functions, and clear explanations of each button’s purpose.
**Low-Tension Stable Sewing:**
Synchronized feeding and take-up mechanisms ensure consistent tension, even under low-thread conditions.
**Perfect Stitch Quality:**
Accurate needle drop and advanced servo control result in clean, parallel stitches that maintain quality even at high speeds.
**Consistent Bottom Thread Tightness:**
Adjustable presser foot height ensures consistent tightness, preventing uneven stitching.
**Easy Head Adjustment:**
No need to tilt the head; adjustments can be made directly via the needle guard.
**Clear Visibility:**
Without a presser foot arm support plate, the workspace is more open and easier to monitor.
