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 is a state-of-the-art solvent-free PU foaming & feeding unit specially developed for synthetic leather coating processes. Adopting solvent-free technology compliant with EU REACH & RoHS environmental standards, the machine delivers stable production for sensitive PU and TPU materials with precise metering and intelligent three-stage process control.
The system features low-speed high-precision metering pumps and dedicated coating heads to guarantee uniform coating thickness of 0.5–3.0 mm. It accurately produces weather-resistant topcoats for automotive leather, lightweight soft coatings for apparel leather, and high-durability finishes for sofa and luggage leather.
The intelligent cleaning system paired with color paste injection pumps shortens color change time from 15 minutes to 3 minutes, greatly improving flexibility for small-batch, multi-variety orders.
Two capacity options are available: 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 to match diverse production scales and special process demands.
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.

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 guarantee uniform coating thickness of 0.5–3.0 mm. Intelligent cleaning system shortens color change time from 15 to 3 minutes.
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.
