Integral Skin PU Foam Molding Solution
Precision reaction injection molding systems for integral skin armrests, headrests, and medical furniture, delivering wear-resistant solid skins and soft cores.
Precision Polyurethane Integral Skin Solutions for Ergonomic & Medical Furniture
Office chair armrests, dental patient chairs, and medical bed headrests require tactile soft-touch comfort combined with heavy scratch resistance and barrier impermeability against harsh hospital disinfectants. Traditional hand-upholstered fabric or PVC vinyl covers feature exposed stitched seams that harbor biological contaminants, trap dirt, and split under repeated mechanical abrasion. Haifeng’s automated high-pressure polyurethane integral skin foaming solution forms a seamless, dense outer skin that chemically transitions into an elastic, shock-absorbing microcellular core in a single mold shot. Operating with eco-friendly water-blown chemistry, it delivers flawless grain replication and durable chemical resistance.

From Material Preparation to Finished Components
Coordinate formulation, metering, forming, curing and finishing around the selected product and production schedule.
Armature Positioning & In-Mold Coating
Metal mounting cores or nylon skeletons are secured onto mold positioning pins; automated or manual guns apply eco-friendly In-Mold Coating (IMC) or water-based release agents onto heated aluminum cavities.
Precision High-Pressure Tilting Injection
Servo displacement pumps inject water-blown self-skinning polyol and isocyanate at up to 190 bar through an anti-drip mixing head, while the mold carrier tilts 15°–45° dynamically to force displaced air upward toward perimeter vents.
Temperature-Driven Skin-to-Core Formation
Liquid contacting the cooler mold surface condenses and crosslinks rapidly into a solid, abrasion-resistant elastomeric outer skin, while the warmer core matrix expands into a resilient microcellular shock absorber.
