PU Steering Wheel Foaming Line Solution
With more than two decades in polyurethane complete equipment, Haifeng Polyurethane Machinery delivers a turnkey PU foaming line for steering wheels, built around delicate surface, precise multi-color, safe efficiency and flexible batch production. The line integrates an HF-HPM series high-pressure foaming machine for steering wheels, a six-station hydraulic mold frame line, a two-pigment six-mixing-head system and an electrical safety control system, covering the full process from raw material metering and mixing, multi-station metered pouring, integral-skin foaming and curing, to mold opening and part removal. Dosing accuracy reaches ≤±0.3% with injection accurate to 0.01 s, and the line suits integral-skin foaming of steering wheels, armrests and other interior parts.
Precision Multi-Color Foaming
Closed-loop two-pigment metering with pigment mixed inside the mixing head; injection time accurate to 0.01 s for small-shot steering wheels.
Safety & Eco-friendly
Six safety light curtains interlocked with PLC, with solvent-free self-cleaning keeping VOC ≤35 mg/m³.
Customized to your steering wheel mold structure and two-color process, the turnkey line is delivered with factory commissioning, pilot production support and after-sales service for stable, high-quality output.
Implementation Process
Our turnkey service covers the full journey from on-site survey and recipe design to commissioning, pilot production and long-term after-sales support.
Customized Solution Planning
Engineers survey on site and customize the solution based on steering wheel mold structure, two-color process, target cycle time and environmental standards.
Integral-Skin Recipe Design
The R&D center completes customized integral-skin recipe and two-color process design with feasibility verification.
Turnkey Equipment Delivery
Core equipment including the high-pressure foaming machine, six-station hydraulic mold frames and electrical safety system is built in our factory, and field engineers complete installation and commissioning.
