UNT Manual Bending Machine
is a professional equipment specially designed for manufacturing polyurethane (PU) elbow duct boards. With precise bending control, convenient operation experience and reliable performance, it has become a powerful tool for the installation and maintenance of heating, ventilation and air conditioning (HVAC) systems.
Core Advantages of Manual Bending Machine
Precise Bending with Controllable Angles
The ergonomically designed operation handle enables precise control over the bending angles of PU boards (such as 90°, 45°), meeting the manufacturing requirements for various elbows and tees in duct systems.
Equipped with a scale adjustment device, it ensures that the angle error of each bend is ≤±0.5°, effectively reducing the risk of air leakage.
Compatibility with Multiple Panel Specifications
Supports PU thermal insulation boards with a thickness of 20mm-50mm, compatible with materials of different densities and hardness.
The adjustable mold design adapts to panel processing with a width range of 100mm-500mm, offering high flexibility.
Protection of Material Structural Integrity
Adopts a progressive pressure system to avoid damage to the closed-cell structure of PU boards during traditional bending, ensuring that thermal insulation performance remains intact.
The mold surface is specially treated to prevent scratches on the board surface, enhancing the aesthetic appeal of the finished product.
Lightweight, Portable, and Flexible Operation
The entire machine weighs only 28kg, with a compact body size (520×310×280mm), making it suitable for operation in construction sites or small spaces.
No power supply is required-manual operation alone can complete bending, particularly suitable for temporary maintenance or outdoor work scenarios.
