High-efficiency thread trimmer features a unified design for the suction port and cutting head, ensuring that excess thread ends are trimmed precisely to within 1 mm, with all severed threads automatically collected in a large-capacity 30-liter waste bin. Electric thread trimmer is powered by a brushless blower motor with a rated output of 450 watts and an adjustable speed range of 3,000 to 28,000 RPM. It offers robust suction power of up to 10 kPa while maintaining a low operating noise level of under 65 dB for a comfortable working environment. Automatic thread trimmer cuts threads without damaging the fabric or affecting overlock and coverstitch seams, delivering impeccable cutting results. This optimizes production workflows and maintains the integrity of the finished garment, increasing production efficiency and reducing costs. Innovative square-profile design provides a 35% larger thread-collection capacity compared to traditional models. The ergonomic handle enables comfortable installation and operation, while the integrated display screen shows real-time speed data for easy adjustments. Safety features include a dedicated negative-pressure relief valve that automatically opens if the filter is clogged or improperly installed, restoring airflow and preventing damage to the motor and circuit board from overload or overheating.
