BROTHER T-8421D-T03-N64D 6.4MM TWIN NEEDLE DIRECT DRIVE Industrial Sewing Machine

Brother T-8421D-T03-N64D Twin Needle 6.4mm Direct Drive Sewing Machine

The Brother T-8421D-T03-N64D is a high-performance twin needle, direct drive, lock stitch machine with a 6.4mm needle gauge. Designed for precision and efficiency, this model is equipped with an intuitive color LCD touch panel, IoT capabilities, and a USB port for easy data management and software upgrades.

Key Features:

User-Intuitive Color LCD Display Touch Panel

• The color LCD touch panel features illustration icons for easy, intuitive operation. Users can choose from three types of home screens: detailed, quick, and easy, all designed for user-friendly interaction.

Needle Breakage Prevention Function

• This model includes a needle breakage prevention function, crucial for thick fabric backstitching. The quick back switch, strategically positioned for easy access, further enhances productivity by preventing needle breakage and point crushing.

Strong Needle Penetration and Reliability

• With a powerful 550W motor, this machine delivers strong needle penetration, ensuring accurate sewing of heavy materials and joints. The built-in vibration control system (patent pending) enhances penetration force when resistance increases, improving sewing reliability.

Improved Control Board Reliability

• The control board design, proven in other models, enhances the machine's ability to handle voltage fluctuations and improves vibration resistance, ensuring safe operation in various environments.

Easy Gauge Replacement

• A cam in the lateral position adjustment mechanism allows for fine adjustments between the needle and rotary hook point, increasing the efficiency of gauge part replacement. The needle drop correction function ensures accurate needle placement even with commercial gauge parts, compatible with parts from previous models.

Versatile Feeding Methods

• This machine features a switchable needle feed and lower feed function, enabling the operator to choose the optimal feed method based on the material and process. Needle feed prevents uneven material feeding, while lower feed is ideal for avoiding puckering and making quick turns.

USB Port on Operation Panel

• The USB port allows for easy copying and sharing of sewing patterns and settings between machines. It also facilitates software upgrades using USB media.

IoT Capabilities for Enhanced Productivity

• The T-8421D-T03-N64D is IoT-compatible, enabling connectivity with Brother’s IoT system for process analysis, management, and productivity improvement.
