Low-Pressure PU Foaming Machine for Display Cabinet Thermal Insulation

Product Overview

Specially customized for thermal insulation layer foaming of refrigerated display cabinets, commercial refrigeration equipment, low-temperature refrigeration appliances.

This equipment is configured for low-pressure PU metering and mixing for refrigerated display-cabinet and commercial refrigeration insulation. Material conditioning and circulation support the selected rigid-foam recipe.

Cabinet geometry, shot mass, material ratio, mold filling and cure conditions are agreed for the actual package. Foam conductivity, cell structure and cabinet thermal performance require separate material and finished-assembly tests.

Operation Workflow

Raw Material Preparation

Prepare polyether polyol and isocyanate at the target mix ratio (100:95-110); ensure both components are properly conditioned and free from contamination.

Tank Loading & Temperature Setting

Load polyether polyol into Tank A and isocyanate into Tank B; the 1A1B independent temperature control keeps both tanks at 25-45°C, with circulation stirring for uniform consistency.

Low-Pressure Metering and Mixing

Meter and mix the two components for the selected rigid-foam formulation. Confirm the ordered circuit pressure, shot and mold filling settings separately.

Foaming & Molding

Inject the mixed material into the display cabinet or refrigeration appliance mold; the foam layer forms uniformly with high closed cell rate, improving thermal insulation performance.
