1. Low-pressure PU foaming machines
Low-pressure PU foaming machines suit flexible polyurethane applications and offer strong performance in precision, consistency and low-maintenance operation.
Equipment advantages include high-precision metering, pressure-safety controls, effective filtration and mixing, intelligent PLC control, comprehensive fault alarms and a complete air-treatment system.
2. High-pressure PU foaming machines
Drawing on nearly 40 years of technical experience, Haifeng’s high-pressure PU foaming machines address the challenge of mixing high-viscosity materials. Key technical parameters and performance include:
Haifeng’s high-pressure foaming machines and patented metering structures help control multi-component ratios. Its proprietary “rigid shell, soft core” multi-hardness zone-forming technology supports one-step molding of complex structures such as automotive cushioning blocks and high-speed-rail vibration-damping pads.
3. Polyurethane sole machines (direct-injection molding machines)
Haifeng is the sole drafting organization for China’s industry standard “Footwear Machinery—Polyurethane Casting Molding Machine” (QB/T 2866-2007) and has extensive expertise in this field. Models are available with 18, 24, 30 and other station configurations.
Solution portfolio: Haifeng provides fully automatic polyurethane sole solutions, automatic rotary-table solutions for directly injected safety footwear, fully automatic production lines for directly injected safety footwear, dual- and multi-density polyurethane molding, low-pressure spraying for polyurethane soles, fully automatic polyurethane rain-boot production and fully automatic transparent-sole production, among other solutions.
4. PU spraying equipment
PU spraying equipment creates seamless surface coatings to improve the appearance of products such as footwear components. Haifeng specializes in polyurethane spraying, foam production, mixing and metering equipment, with solutions for automotive, construction, furniture and industrial applications.
Key technical features:
- Spraying technology: Patented technology avoids entrained bubbles and distributes foaming material evenly throughout the mold to fill it completely.
- Applications: Especially suitable for seamless surface coating and appearance enhancement of footwear components.
- Core processes: Low-pressure spraying and high-precision casting and foaming.
- Environmental compatibility: Supports water-based and solvent-free spraying systems.
Haifeng also provides low-pressure spraying solutions for polyurethane soles and standard spraying solutions.
5. Continuous sponge-foaming production lines
Continuous sponge-foaming production lines enable large-scale continuous production of flexible polyurethane foam and are suitable for high-volume, standardized manufacture of flexible PU sponge.
6. Continuous sandwich-panel production lines
Continuous sandwich-panel production lines automate the manufacture of polyurethane panels for building roofs and walls.
- Control system: A highly integrated, coordinated system centralizes control points at the main control center, enabling coordinated line-wide parameters, fault self-diagnosis and remote control.
- Safety and compliance: Supports cyclopentane foaming explosion-protection solutions that meet international standards.
7. RIM equipment (reaction injection molding equipment)
RIM equipment supports reaction injection molding and is suitable for large, complex parts such as automotive bumpers. Haifeng supports casting, dispensing, molding, foaming and injection processes.
- Applications: Integrated robotic equipment for three-dimensional path spraying and foaming in automotive and rail-transit industries.
- Customization: Polyurethane casting solutions for automotive interior parts such as steering wheels, headrests and armrests, supporting high-resilience and integral-skin processes.
8. Automated polyurethane production lines
Automated polyurethane lines include rotary-table lines and customized non-standard lines for production across multiple industries.
Key parameters:
- Station configurations: Flexible configurations with 12, 16, 20, 24, 32 and 40+ stations, with scalable customization.
- Mixed-model production: Modular rotary-table designs support barcode identification and independent material control for flexible production of products with different specifications and hardness levels on the same line.
- Robot integration: Integrated robotic arms perform automatic three-dimensional path spraying and dispensing on complex surfaces, substantially reducing manual intervention.
- Safety and compliance: Corrosion-resistant flow paths made from 304/316L stainless steel support long-term compliant operation in highly flame-retardant and explosion-proof environments.
9. Complete polyurethane plant solutions
Haifeng provides end-to-end EPC+M+O capability and turnkey lifecycle services spanning engineering (E), procurement (P), construction (C), manufacturing (M) and operations (O).
Service scope:
- End-to-end support from pre-sales process consultation and pilot trials through complete-line delivery.
- Lifecycle services for process design, equipment integration, installation, commissioning, personnel training and ongoing maintenance.
- A 15,076 m² manufacturing base and coordinated resources across multiple locations help keep delivery schedules controllable and quality traceable.
