Polyurethane Foaming Machine
I. Product Description
The polyurethane foaming machine is specialized equipment for producing polyurethane foam (PU Foam). It works by precisely mixing polyol and isocyanate, which rapidly undergo a chemical reaction to generate polyurethane foam materials with properties like thermal insulation, sound insulation, cushioning, and light weight. This equipment is widely used in building insulation, furniture and seating, automotive interiors, cold chain insulation, home appliance packaging, footwear materials, and other fields, capable of producing various types of polyurethane foam such as rigid foam, flexible foam, self-skinning foam, and high-resilience foam.
II. Equipment Advantages (Core Selling Points)
Efficient Mixing System: Utilizes high-pressure impingement mixing or high-speed stirring to ensure uniform mixing of A/B components and excellent foaming effect.
Precise Metering System: High-precision metering pumps guarantee accurate ratio of polyol to isocyanate (typically 1:1 ~ 1:5).
Multi-functionality: Supports various foaming processes including rigid foam, flexible foam, self-skinning foam, high resilience, slow rebound, etc.
Automated Control: PLC control automatically adjusts temperature, pressure, and flow rate; easy operation and high stability.
Modular Design: Configurable with high-pressure machines, low-pressure machines, pouring machines, foaming lines, etc., according to需求.
