Engineered for High-Resilience, Precision-Foamed Automobile Headrests
The HF-HPM-1A1B-HeadrestPIP is a high-pressure PU foaming machine for automobile headrest production, with ≤±0.3% metering accuracy and an 8/10/12-station turntable line.
This high-pressure PU foaming machine is specially designed for high-resilience polyurethane foaming production of automobile headrests. It can form a headrest PIP polyurethane foaming line together with a mixing head and a turntable line: the high-pressure foaming machine completes two-component high-pressure impingement mixing and metered injection, the mixing head ensures precise shot volume, and the turntable line with 8, 10, or 12 stations achieves multi-station cyclic continuous production. The complete line can be customized to customer requirements, or individual units such as the foaming machine, mixing head, and turntable can be purchased separately. The machine is equipped with polyether polyol and isocyanate metering units, two-component flow control, a high/low-pressure cycle switching system, a pressure limiting and control system, and a hydraulic unit, ensuring stable injection without pressure build-up or dripping. It meets the mass-production needs of small-shot headrests with consistent density, efficient cycles, comfortable resilience, and fine molding appearance.
Production Workflow
Raw Material Preparation
Prepare polyether polyol and isocyanate at the target mix ratio (100:45-60) for the high-resilience headrest foam recipe, with proper conditioning for uniform cells.
Turntable & Temperature Setting
Load polyol into Tank A and isocyanate into Tank B; the 1A1B temperature control maintains 20-45°C, while the 8/10/12-station turntable positions molds for cyclic production.
Precise High-Pressure Metering & Injection
The closed-loop flow-meter dosing system (≤±0.3%) dispenses precise shot volumes; the mixing head injects under 10-18 MPa at 7000-12000 r/min without pressure build-up or dripping.
Foaming, Curing & Mold Cycle
The material foams and cures in the turntable mold; the line advances to the next station, with solvent-free air purge cleaning preparing the system for the next cycle.

Key Advantages
Six equipment and process features to consider when configuring a high-pressure PU foaming machine for automobile headrests.
Precise Injection with Closed-Loop Flow Control
Metering units with metering pump, safety valve and VFD motor plus closed-loop flow-meter control achieve dosing accuracy ≤±0.3% for precise shot volume and consistent density.
Stable High/Low-Pressure Circulation
Automatic high/low-pressure cycle switching keeps pressure stable between injections, preventing material settling, pressure build-up and dripping.
Flexible Turntable Customization
8/10/12-station turntable options; the complete line is customizable or units can be purchased separately, with one-click multi-formula changeover for flexible production.
Eco-Friendly Solvent-Free Cleaning
Automatic air purge cleaning with no chemical solvents, meeting passenger-car cabin air quality requirements for clean production.
PLC Intelligent Control with Multi-Formula Storage
PLC control with one-click multi-formula switchover and fault self-check reduces manual errors and enables rapid changeovers between headrest styles.
Small-Shot Mass Production Efficiency
High-resilience foam metering and stable circulation deliver consistent density, comfortable resilience and fine molding for mass small-shot headrest production.
