Motorized 3-Roll Bending Machine For Mica Band Heater Manufacturing

1. Product Title

Motorized 3-Roll Bending Machine for Mica Band Heater Manufacturing

2. Key Highlights 

• Motor-Driven Efficiency: Powered by a 1.5kW pure copper motor and NMRV75 worm gear reducer, delivering steady torque and consistent rolling speed for high-volume production.

• Precise Cylindrical Bending: Designed specifically for mica band heaters, effortlessly bending sheath plates up to 600mm wide into uniform, tight cylinders down to ~100mm in diameter.

• Heavy-Duty Alloy Rollers: Precision-machined top/bottom rollers (72mm) and offset roller (82mm) ensure smooth, even curvature without wrinkling outer sheaths or damaging internal mica insulation.

• Rugged Mechanical Construction: Built to handle sheet metals with yield strength up to 245 MPa, offering long-term reliability and reducing labor fatigue.

3. Product Overview 

Electric-Powered Precision for Band Heater Fabrication

This Motorized 3-Roll Bending Machine is engineered specifically for forming the outer metal sheaths in Mica Band Heater manufacturing. Driven by a 1.5kW heavy-duty pure copper motor paired with an NMRV75 worm gear reducer, it replaces manual bending methods to provide consistent quality, higher output, and reduced operator effort.

Protective & Uniform Rolling

Featuring a hardened alloy 3-roller configuration (72mm top and bottom rollers with an 82mm offset roller), the machine distributes bending force evenly across the workpiece. This ensures clean, wrinkle-free cylindrical shapes on stainless steel, galvanized steel, or brass sheets up to 600mm wide, while preserving the integrity of internal mica layers and heating elements.
