Low Pressure Polyurethane Injection Machine: High-Quality PU Foaming Equipment

The injection output range is 2–6000 g/s, adjustable to match different part sizes and production requirements.

Mixing ratio is adjustable within the range 100:30 up to 100:200. The mixing head runs at 2800–5000 rpm and uses forced dynamic mixing for consistent homogeneity.

Material tank volumes can be customized from 30 L up to 500 L to suit production scale and material usage.

Compressed air must be dry and oil-free with pressure 0.6–0.8 MPa and flow ~600 NL/min (customer-provided). Nitrogen is required at ~0.05 MPa and ~600 NL/min (customer-provided).

Standard input power is three-phase five-wire 380 V, 50 Hz. Rated power depends on configuration and ranges from about 8 kW to 25 kW. Other power specifications can be customized on request.

Yes — the listed temperature control (heating) system spec is 2 × 3 kW. Additional heating/cooling options can be customized for specific materials and processes.

Typical overall dimensions are 3200 mm (L) × 1650 mm (W) × 2650 mm (H). Weight ranges from approximately 1000 kg to 1500 kg depending on configuration. Allow extra space for service access and material handling.

Common applications include pillow and cushion foaming, chair and car seats, steering wheels, bumpers, integral skin, fast/slow rebound foams, toys, insulation filling, bicycle cushions, soles, medical equipment components, and architectural moldings.

Yes. The machine can be customized for different output capacities, mixing ratios, power requirements and exterior colors (standard options: white/red/blue). Discuss your process requirements with the supplier to specify custom options.

Routine maintenance includes cleaning the mixing head and injection nozzles after runs, replacing/cleaning air and material filters, checking seals and hoses for wear, verifying temperature control and heater function, and periodic calibration of mixing ratios and pump outputs.

Operate in a well-ventilated area, use appropriate PPE (gloves, goggles, respirators as required), ensure proper grounding, keep compressed air and nitrogen supplies dry and oil-free, isolate and contain chemical spills, and follow local regulations for handling and disposal of polyurethane components and waste.

Manufacturers/suppliers typically offer factory acceptance testing, on-site commissioning, and operator training. Confirm available training levels, manuals and after-sales support with your supplier prior to purchase.

Common spares/consumables include mixing tips/nozzles, seals and O-rings, filter elements, pump seals, sensor elements, and replacement heaters. The supplier can provide a recommended spare-parts list based on your production schedule.

Contact the equipment supplier or authorized dealer with your required configuration (output, tank sizes, power supply, mixing ratio, and any custom options). They will provide quotes, lead times, warranty terms and after-sales/service agreements specific to your order.
