Product Parameters
| Parameter | Model：HF-LPUE-2A2B-Auto-Buffer |
|---|---|
| Dosing Rate | 50～1200 g/s |
| Shot Weight Per Mold | 50～500 g/mold |
| Mix Ratio | Polyether Polyol : Isocyanate = 100:40~90 |
| Tank Capacity | 200L / 250L (optional, per tank) |
| Mixing Head Speed | 1500～3500 r/min |
| Dosing Accuracy | ≤±0.4% |
| Metering Pump Flow | 0.5～10 kg/min |
| Tank System | 2A2B two-component system + independent modifier tank for resilience |
| Temperature Control | Tank A: 25~55℃; Tank B: 20~45℃ |
| Mold Temperature Control | 40~80℃ (external mold heater) |
| Casting Pressure | 0.3～1.5 MPa |
| Cycle Time | 90~150 sec/mold |
| Cleaning System | Pneumatic liquid cleaning + automatic air purge |
| Power | 5.5～12 kW |
| Control System | PLC touch control + formula storage |
| Application System | Two-component polyurethane elastomer (CPU) / microcellular elastomer system |
| Warranty | 1 Year |
| Certification | CE, ISO9001, Complies with general specifications for automotive parts production |
Application Scenarios
Suitable for mass production of polyurethane buffer blocks for passenger vehicles and commercial vehicles, including suspension buffer pads, limit buffers, chassis anti-collision cushions, and rebound components. Using solid/microcellular elastomer technology, the finished parts feature dense structure, shock absorption, compression resistance, wide temperature tolerance, and low compression set. They meet the requirements of automotive assembly lines and OEM quality standards.
Core Advantages
Dedicated low-pressure elastomer process with gentle mixing (no overheating), producing pore-free parts with resilience ≥85%, stable performance and no cracking/deformation in long-term use.
Independent modifier tank supports adjustable hardness (35~65 Shore A), compatible with buffer blocks for various vehicle types.
Precise temperature and dosing control ensure minimal deviation in hardness and density between batches, meeting high-precision automotive requirements.
Low power consumption, easy maintenance, 24-hour continuous operation, suitable for standardized automotive production lines.
