Polyurethane Rail Pad Casting Solution
Build a rail pad production workflow with controlled material preparation, mold handling and process records.
Build the Process Around Your Product
Build a rail pad production workflow with controlled material preparation, mold handling and process records.
Product and material first
Start with the finished-product drawing, material system and acceptance requirements. The process route and equipment configuration are assessed together.
Capacity across the whole process
Define output with preparation, forming/reaction, curing, handling and inspection included. The slowest stage and product changes determine practical line capacity.
Haifeng provides the casting core and agreed mold-handling automation. Material validation and rail qualification follow the customer’s specified product requirements.
From Preparation to Qualified Product
A planning sequence for the specified route. Final settings and acceptance conditions are established through material and part review.
Define pad performance
Review pad drawing, stiffness, damping, fatigue and environmental requirements for the fastening system.
Prepare materials and tooling
Confirm solid or microcellular chemistry, inserts, mold heating and venting.
Meter and cast
Coordinate recipes, shot size and dispense positions with mold cavities.
Information Needed to Configure the Line
Provide these inputs so the equipment range, interfaces and validation plan can be defined.
| Design input | Information required |
|---|---|
| Pad drawing | Geometry, cavities, inserts and fastening interfaces |
| Performance requirements | Stiffness, fatigue, damping and specified rail qualification tests |
| Material system | Component count, density target and cure conditions |
| Production goals | Parts/shift, mold count, handling and traceability |
Core Equipment and Integrated Interfaces
Haifeng provides the casting core and agreed mold-handling automation. Material validation and rail qualification follow the customer’s specified product requirements.
PU Elastomer Casting Machine | Railway Engineering
PU casting unit designed for railway engineering components, offering excellent wear resistance and impact strength. Ideal for track fasteners, vibration pads, and rail infrastructure.
Low-Pressure PU Foaming Machine | Railway Damping Pads
A high-performance PU foam casting system developed for industrialized manufacturing of elastic pads for high-speed railways, heavy-haul railways, subways and full rail transit systems.
Coordinate the Equipment With the Process
Evaluate repeatability, handling and acceptance across the full workflow.
Material-specific configuration
Component circuits, thermal control, mixing and receiving equipment are matched to the approved chemistry and processing window.
Defined interfaces
Haifeng provides the casting core and agreed mold-handling automation. Material validation and rail qualification follow the customer’s specified product requirements.
Documented acceptance
The proposal defines trials, process records, inspection responsibilities and product-specific acceptance conditions.
