PU Duct Fabrication Tool

PU Duct Fabrication Tool is a specialized processing tool kit designed for PU (polyurethane) / PIR (polyisocyanurate) pre-insulated duct sheet materials. It belongs to the core supporting tools for the prefabricated duct installation in the HVAC (heating, ventilation, and air conditioning) field.

Different from the traditional metal duct cutting equipment, it is specifically optimized for lightweight and insulation composite sheets, taking into account the portability for on-site construction and the factory prefabrication accuracy. It is a key product that replaces manual saws and enhances the standardization of duct production.

PU Duct Fabrication Tool is a specialized kit for cutting, grooving and shaping PU/PIR pre-insulated duct panels in HVAC systems. It ensures precise angles, smooth edges and airtight joints, boosting on-site efficiency and quality for duct fabrication.

Core Components of PU Duct Fabrication Tool

The entire set of tools is centered around the angle cutting system, complemented by auxiliary measuring and fastening tools, covering all processes of duct fabrication:

Angle cutting tool set: Includes 45°/22.5° double-edge knives, left and right 45° angled knives, and 90° straight-cut knives, capable of performing V-shaped grooves, angled connections, and straight-edge cuts, meeting the processing requirements for elbows, trisets, and other irregular parts.

Auxiliary tools: High-precision tape measure, adjustable marking tool, anti-buckling hammer, spare blades, etc., ensuring precise measurement, smooth cuts, and tight jointing.

Optional equipment: Manual bending machine, small CNC cutting machine, suitable for different batch requirements - the manual model is flexible and low-cost, while the CNC model has a precision of ±0.1mm and efficiency increased by more than 5 times.

Performance Advantage of PU Duct Fabrication Tool

High precision, low loss: The dedicated cutting tools achieve precise positioning, leaving no burrs or deformations in the cuts, and the joint gaps are tight. The leakage rate is significantly lower than that of manual cutting, enhancing the air tightness and energy efficiency of the duct system. The angle error is controlled within ±0.5°, reducing the need for secondary trimming processes.

High efficiency and portability, wide compatibility: The tool is designed for lightweight, allowing one person to operate it. It is suitable for operations in narrow spaces on construction sites; it is compatible with PU/PIR boards of different thicknesses ranging from 20 to 50mm, covering rectangular straight pipes, arc-shaped elbows, and irregular three-way fittings, among other mainstream duct shapes. Both small-batch manual processing and large-batch CNC production can be adapted.

Durable and economical, easy maintenance: The high-carbon steel blades have high hardness and excellent wear resistance, and come with multiple sets of spare blades to extend their service life.
