    We designed this machine specifically for small factories and startups. It’s priced competitively without cutting corners on quality. It replaces 3-4 manual workers, cutting your labor costs by 70%. Most of our customers recoup their investment in 8-12 months.

    Unmatched Production Efficiency & Labor Savings

    Consistent precision, no more wasted material

    Manual cutting and bending always leads to inconsistent sizes and wasted material. This 6-station forming machine produces perfectly straight, uniform uprights every single time. The hydraulic punching system ensures holes are perfectly aligned, so shelves assemble smoothly without any grinding or rework.

    High-Grade Materials & Long Service Life

    Built tough for years of daily use

    This machine is overbuilt to handle daily production. The 25mm thick solid side plates eliminate vibration and shaking. The rollers are made of premium Cr12MOV steel, quenched to HRC58-60° for maximum wear resistance. It will run reliably for 10+ years with only basic maintenance.

    Precise Forming Meeting International Standards

    Dead simple to operate and maintain

    The intuitive touch screen interface makes this machine a breeze to run. Any regular worker can master it in 15 minutes of training. There are no complicated parts to break, and maintenance is straightforward. We also provide free lifetime technical support if you ever run into issues.
