Headrest PIP Foaming Line Solution
Configure PU pour-in-place headrest production with material preparation, dispensing and rotary mold handling for your headrest construction and output.
Headrest PIP Foaming Line Solution
With more than two decades in polyurethane complete equipment, Haifeng Polyurethane Machinery delivers a turnkey PU foaming line for automobile headrests, built around precise injection, consistent density, efficient cycle and flexible changeover. The line integrates an HF-HPM series high-pressure foaming machine, a mixing head and a turntable line with selectable 8-station, 10-station or 12-station configurations, covering the full process from raw material metering and mixing, metered injection, foaming and curing, to mold opening and part removal. Dosing accuracy reaches ≤±0.3% with density fluctuation of ≤±3%, and the automatic high/low-pressure cycle switching keeps injection stable.
Precise Injection & Consistent Density
Closed-loop metering with metering pump, safety valve and VFD keeps density fluctuation ≤±3%.
Stable Injection & Flexible Turntable
Automatic high/low-pressure switching prevents build-up and dripping; 8/10/12-station optional.
Customized to your headrest mold and cycle targets, the turnkey line is delivered with commissioning, pilot production support and after-sales service; individual units can also be purchased separately.
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 determine turntable station count and line configuration based on headrest mold structure, target cycle time and environmental standards.
High-Resilience Recipe Design
The R&D center completes customized high-resilience recipe and process design with feasibility verification.
Turnkey Equipment Delivery
Core equipment including the high-pressure foaming machine, mixing head and turntable line is built in our factory, and field engineers complete installation and commissioning.
