Haifeng successfully installed and commissioned a continuous flexible polyurethane padding production line for a premier furniture upholstery supplier in Argentina, stabilizing core foam density within ±1.2 kg/m³ across ultra-soft padding and viscoelastic grades. The turnkey delivery encompassed high-precision dynamic chemical metering units, an environmental air-injection nucleation module, an enclosed flat-top conveyor tunnel, and automated cross-cut systems.

Prior to commissioning, the manufacturer operated discontinuous box foaming units to produce padding inserts. Box foaming caused uneven exothermic heat dissipation, creating dense, un-aerated hard spots along the edges and loose, collapsed structures in the center. The client required a continuous, industrial-scale production line capable of handling variable polyol polyaddition reactions, injecting microscopic air nucleating bubbles, and delivering continuous, soft-touch padding blocks with high air permeability.

Operating since February 2023 on a single-shift production schedule across an 1,100 m² bay, the plant delivers premium foam padding for high-end sofas and armchairs. By deploying Haifeng's closed-loop mass flow regulation and dynamic air nucleation system, the client manufactures breathable, luxurious furniture padding blocks that satisfy strict consumer comfort standards.

Project Technical Specification Matrix:

Reference customer application output: 300 kg/min. The described equipment configuration range is 300–450 kg/min; the configuration range is distinct from the customer operating value.

Haifeng deployed a versatile continuous slabstock foaming workcell tailored for ultra-soft comfort and viscoelastic memory foam formulations:

1. Precision Air Nucleation System: Micro-volume compressed air is continuously dissolved into the polyol stream via a high-pressure injector, creating dense, fine micro-cells with 92% open-cell content.
2. Dynamic 6-Component Metering: Inverter-controlled metering pumps regulate auxiliary blowing agents and soft-segment polyols to eliminate center core scorching.
3. Enclosed Vapor-Scrubbed Tunnel: The 30m conveyor operates under negative pressure, venting reaction exotherm and VOC gases through active carbon filters.
4. Automated Cut-Off & Weighing: An inline traveling circular blade cuts the block to preset lengths, transferring buns onto integrated weigh-scales for real-time density tracking.

Installation and commissioning: 30 days. Operator training: 5 days. Warranty: 1 year. Long-term spare parts and remote PLC diagnostic support are available.
