Product Overview
Specially built for general polyurethane foam pouring molding, widely suitable for foam production in furniture, automotive interiors, packaging, sports equipment and other industries.
This general foam PU pouring machine is purpose-built for flexible, semi-rigid, and rigid foam production across multiple industries. The 2A2B main tanks plus functional additive tank enable quick switching of flame retardant, antistatic, and other functional formulas, greatly expanding application scenarios. The wide-flow precise pouring design (100–2500 g/s) is perfectly suited for large mold production, effectively improving product qualification rate and production stability. The multi-formula flexible compatible system allows foam switching without core parts replacement, with one‑key operation that improves line efficiency. Coordinated temperature control and metering supports long‑hour continuous operation, stably meeting mass order delivery requirements. Applicable equipment and material documentation is reviewed for the selected configuration and destination market.
Operation Workflow
Raw Material & Additive Preparation
Prepare polyether polyol and isocyanate (TDI/MDI) at the target ratio (100:80-110); load flame retardant, antistatic and other additives into the dedicated additive tank.
Tank Loading & Temperature Setting
Load polyol into Tanks A1/A2 and isocyanate into Tanks B1/B2; set Tank A to 25–50°C and Tank B to 20–40°C for optimal foam formulation.
Precision Metering, Mixing & Pouring
The PLC-controlled dynamic metering system dispenses precisely; the mixing head runs at 4000–8000 r/min under 0.8–2.0 MPa foaming pressure, with 100–2500 g/s for different mold sizes.
Foam Molding & Curing
The mixed material is poured into molds for foam formation; the multi-formula system supports flexible, semi-rigid, and rigid foam switching without core parts replacement.
