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.
8. Which applications and products is this PU foaming machine suitable for?
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.
9. Can the machine be customized for specific materials, outputs or colors?
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.
10. What routine maintenance is required?
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.
11. What safety and environmental precautions should operators follow?
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.
12. Is operator training and commissioning support provided?
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.
13. What spare parts and consumables should be kept on hand?
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.
14. How do I get pricing, lead time, warranty and service details?
