Product Overview
Specially designed for polyurethane rigid foam insulation of cold storage, cold chain warehouses, cold storage boards and refrigerated carriages.
This low-pressure PU foam machine is purpose-built for polyurethane rigid foam insulation of cold storage facilities, cold chain warehouses, cold storage boards, and refrigerated carriages. The 2A2B four-tank multi-formula system suits complex cold storage rigid foam formulations, ensuring stable material supply without cross-contamination and enabling seamless switching between formulations. Ultra-high flow wide-range pouring (300–6000 g/s) is ideal for cold storage boards and large boxes, delivering full molding without defects and improving insulation quality. Special high-speed mixing (10,000–15,000 r/min) with precise temperature control (20–60°C) produces high closed cell rate and low thermal conductivity for long-term stable insulation. The solvent-free eco-friendly cleaning system meets long-hour continuous production needs, stably guaranteeing high insulation, flame retardancy, and low thermal conductivity.
Operation Workflow
Multi-Formula Raw Material Preparation
Prepare polyol and isocyanate components for up to four formulations; the 2A2B four-tank system enables flexible switching without cross-contamination.
Tank Loading & Precise Temperature Setting
Load materials into the 2A2B four-tank system and set precise temperature control within 20-60°C for each tank to condition rigid foam formulations optimally.
High-Speed Mixing & Ultra-High Flow Pouring
The PLC metering system (accuracy ≤±0.3% full range) dispenses precisely; mixing head runs at 10,000-15,000 r/min, with 300-6000 g/s pouring for full filling.
Foaming, Curing & Quality Inspection
The mixed rigid foam is injected into cold storage board or box molds; high-speed mixing with precise temperature control ensures high closed cell rate and low thermal conductivity.
