Product Overview
Specially designed for polyurethane elastomer pouring in railway engineering, widely suitable for track expansion joint sealing, sleeper filling, switch cushion, track base leveling and sealing.
This PU cast unit is purpose-built for railway engineering applications, including track expansion joint sealing, sleeper filling, switch cushion, and track base leveling. The 2A2B two-component system includes a dedicated anti-aging and anti-vibration additive tank, providing long-term resistance to outdoor erosion, UV, rain, and train vibration, suitable for long-term outdoor railway working conditions. Dynamic precise metering and controllable pouring pressure ensure full and dense filling of track expansion joints and sleepers with uniform stress distribution. Precise temperature control across a wide range adapts to complex outdoor construction environments with controllable curing speed. The machine bonds strongly with steel rails and concrete substrates and is usable with mobile working vehicles, meeting high-load and high-efficiency railway construction requirements while ensuring track stability and driving safety.
Operation Workflow
Raw Material & Additive Preparation
Prepare polyurethane prepolymer and MOCA curing agent at the target mix ratio (100:10-14); select anti-aging and anti-vibration additives and load them into the dedicated additive tank.
Tank Loading & Temperature Setting
Load prepolymer into Tank A and MOCA curing agent into Tank B; set Tank A temperature to 30-80°C and Tank B to 90-115°C according to the curing agent requirements.
Metering, Mixing & Precision Pouring
The PLC metering system (accuracy ≤±0.3% full range) dispenses precisely; the mixing head runs at 6000-10000 r/min, with pouring rate (120-1800 g/s) and pressure (1.2-2.8 MPa) adjustable for track filling.
Curing & Quality Inspection
Allow the poured elastomer to cure; precise temperature control ensures controllable curing speed without affecting railway schedules, and filled areas are inspected for full, dense filling with uniform stress distribution.
