Product Overview
An integrated low-pressure foaming & feeding unit for solvent-free PU leather coating, serving automotive, sofa, garment, luggage leather & luxury labels with precise metering and intelligent control.
The HF-LPM series meters and mixes materials for a configured solvent-free PU synthetic-leather coating process. Coating thickness and changeover time depend on formulation, substrate, coating equipment and cleaning procedure. The previously stated 0.5–3.0 mm coating range and 15-to-3-minute color-change comparison are supplied reference values requiring trials on the selected line. Chemical compliance is assessed using the selected raw-material documents and finished-material test records, separately from equipment configuration.
Synthetic Leather Coating Production Workflow
Raw Material & Formula Preparation
Load polyol and isocyanate components into tanks; set mix ratio (1:1 ~ 1:4) via patented software for various formulas based on leather type requirements.
Precision Metering & Mixing
Precisely meter components using low-speed high-precision metering pumps with ±0.3% accuracy; mix at 8,600 rpm with intelligent three-stage control for homogeneous dispersion.
Coating Application
Apply the mixed PU coating onto substrate using dedicated coating heads; maintain uniform thickness (0.5–3.0 mm) per leather type specifications with real-time dynamic adjustment.
Curing & Finishing
Cure the coated synthetic leather under controlled conditions; inspect for surface quality, thickness uniformity, and perform final finishing per end-use requirements.
Technical Specifications
All data are based on standard factory testing conditions. Values are for reference; actual performance may vary with formulation and operating environment.

Key Advantages
The HF-LPM Series integrates intelligent three-stage control, optimized process design, eco-friendly solvent-free technology, and flexible customization to meet the demanding requirements of modern synthetic leather production.
Intelligent Three-Stage Control System
Real-time dynamic adjustment of raw material ratio and flow rate with industry-leading computing precision. Supports full material consumption tracking to cut raw material waste by 10%–15% and reduce energy usage by 10%–30%. Automatic production reports support full quality traceability.
Optimized Process Design for Leather Production
Compatible with line widths from 1500–2200 mm. Low-speed high-precision metering pumps and dedicated coating heads supports uniform coating thickness of 0.5–3.0 mm. Intelligent cleaning system shortens color change time from 15 to 3 minutes. Confirm results for the selected formulation and operating conditions.
Eco-Friendly Solvent-Free Solution
Non-toxic, odorless solvent-free technology with near-zero VOC emissions. Fully meets EU REACH & RoHS standards and stringent odor requirements for automotive interiors. Sealed tanks and automatic cleaning systems reduce operator exposure risks.
Flexible Customized Configuration
Two capacity options: 1A1B for small-batch trial production and 2A2B for mass manufacturing. Customizable add-ons include extended web width, color dosing systems, remote monitoring and full data traceability.
Multi-Industry Compatibility
Tailored solutions for automotive leather (1.2–2.0 mm, 30,000 flex cycles at -20°C), sofa leather (1.6–3.0 mm high-elastic coating), garment leather (0.5–1.0 mm lightweight), luggage leather and luxury labels.
Superior Production Efficiency
Production efficiency rises by 30%–60% with comprehensive operating cost reduction. Solvent-free technology slashes solvent procurement and waste disposal costs while meeting strict environmental standards for global markets.
