**High-Speed Sewing Performance (2800 Stitches/Min)**
With a 3.0mm stitch length, this machine achieves an impressive 2800 stitches per minute. It uses a direct-drive servo motor from Mingling, allowing faster start-up and stopping compared to traditional mechanical models. This results in a 28% reduction in operation time and improved productivity.
**Testing Environment:**
- Stitching Pattern: Rectangle (300 x 200 mm)
- Stitch Length: 3.0 mm
- Sewing Speed: 2700 stitches/min (traditional model) vs. 2800 stitches/min (MLK-342H)

**Increased Penetration Force**
Equipped with a powerful 750W servo motor, the MLK-342H delivers stronger penetration force even at low speeds. This allows for efficient sewing of thick materials without compromising quality.
---
**Low Power Consumption**
The direct-drive system is energy-efficient, reducing power consumption by about 15% compared to similar models. This makes it one of the most energy-efficient computerized sewing machines available on the market.
---
**Precise Fabric Positioning**
The machine features a double-step clamp that can stop mid-air and then descend to the lowest position. Users can set a suitable height in the middle, enabling quick and accurate positioning of fabric, reducing errors, and saving cycle time.
---
**Easy Pattern Change**
Changing the clamp is simple—just remove 4 screws and install the new one quickly. The feed plate can also be accurately positioned using reference holes on the bottom plate.
---
**Large Memory Capacity**
The machine can store up to 999 patterns and 500,000 stitches. With support for SD cards and USB drives, users can easily transfer and manage data between machines or computers.
---
**User-Friendly LCD Touch Panel**
The touch panel offers advanced control, including pattern confirmation, sensor status monitoring, and individual function settings. It supports shortcut buttons for frequently used patterns and includes a simple explanation feature for each button.
---
**Low Tension Stable Sewing**
The high-precision feeding device and synchronized needle bar/take-up mechanism allow for stable sewing under low tension conditions, ensuring consistent stitch quality.
---
**High-Speed Sewing with Perfect Stitch Appearance**
At 2800 rpm, the machine maintains excellent stitch quality and production efficiency. Its advanced servo control and steel feeding system ensure precise stitching, even when working with thick materials.
---
**Consistent Bottom Thread Tightness**
Users can adjust the pressure foot height via the control panel, ensuring consistent thread tightness regardless of material thickness. This prevents issues like over-tightening or under-tightening.
---
**Easy Adjustment Without Tilting the Head**
The needle guard can be adjusted without tilting the machine head, making it easier to align the needle and hook.
---
**Wide Field of Vision**
Without a presser foot arm support plate, the machine provides a clear view of the work area, making inspection and fabric positioning more convenient.
