SL.PLM series is a perfect integration of mechanics, electronics, and software engineering, which allows any worker to make repetibly precision lasts without technical compromise. Different from traditional technology, SL. PLM series machine have  hydraulic clampers to grip the dovetails on the conetop of the roughly turned last blocks. Turning without support on the last toe and heel realizes the perfect complete last turning. For each working cycle, it takes about 5-6 minutes to run depending on the size and pitch.
