JUKI LH-3528A-SF-7WB/AK135 DIRECT-DRIVE TWIN NEEDLE LOCKSTITCH

Juki LH-3528A-SF-7WB/AK135 Direct-Drive Medium-Weight Twin Needle Lockstitch Machine with Automatic Thread Trimmer

The Juki LH-3528A-SF-7WB/AK135 is a high-performance, semi-dry head twin-needle lockstitch machine, purpose-built for medium-weight materials. Part of the advanced LH-3500A Series, it combines energy-saving direct-drive technology, exceptional stitch quality, and versatile feed options to deliver unmatched efficiency in garment and upholstery production.

Key Features:

• Direct-Drive Energy Efficiency: Equipped with a compact 500W high-torque motor and SC-920A control box, this model reduces power consumption by up to 21% while increasing material penetration force by 32%, making it ideal for multi-layer sewing.

• Semi-Dry Head Technology: Eliminates oil stains on fabrics by using a sealed lubrication system with minute-quantity oiling in the hook section.

• Changeable Feed System: Easily switch between needle feed and bottom feed to match your fabric type and prevent puckering, especially on lightweight materials.

• Adjustable Thread Tension: Two advanced thread tension control mechanisms provide consistent, well-tensed seams whether working with fine or thicker threads.

• Micro-Lifter Presser Foot Adjustment: Fine-tune presser foot height to handle elastic or textured materials without distorting the fabric’s surface.

• Reliable Thread Trimming: Enhanced direct-acting thread trimmer cuts needle and bobbin threads cleanly, even when using thick thread, and features improved bobbin thread retention.

• Dual Oiling Options: Choose between the Eco-oil circulation system (filtered and recirculated oil) or the Clean Oil method (fresh oil supply to the hook) depending on production needs.

• Production Support Functions: Integrated CP-18A/CP-180A panels offer output control, operation measurement, and bobbin counting to streamline workflow.
