One-Step TPU Reaction and Pelletizing Solution
Coordinate direct reaction feeding of polyol, isocyanate and chain extender with the selected TPU reaction and finishing route.
Build the Process Around Your Product
Coordinate direct reaction feeding of polyol, isocyanate and chain extender with the selected TPU reaction and finishing route.
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 core scope is reaction feeding, multi-component metering, mixing and casting where selected. Twin-screw reactive extrusion, underwater pelletizing, dewatering and drying can be included as supporting equipment with explicit interface ownership.
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 TPU grade and route
Review chemistry, additives, intended grade and whether reaction occurs in a reactive extruder or a casting/curing arrangement.
Prepare and feed components
Specify conditioning, drying where required and independent component ratio control.
Meter and mix
Synchronize multi-component delivery with the reaction equipment and validated reaction window.
Information Needed to Configure the Line
Provide these inputs so the equipment range, interfaces and validation plan can be defined.
| Design input | Information required |
|---|---|
| TPU formulation | Polyol/isocyanate/extender, additives, ratios and viscosity |
| Reaction architecture | Extruder-fed or casting/curing route with validated interfaces |
| Production target | kg/h, grades, changeovers and reaction data |
| Pellet specification | Size, moisture target, quality tests and packaging |
Core Equipment and Integrated Interfaces
Haifeng core scope is reaction feeding, multi-component metering, mixing and casting where selected. Twin-screw reactive extrusion, underwater pelletizing, dewatering and drying can be included as supporting equipment with explicit interface ownership.
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 core scope is reaction feeding, multi-component metering, mixing and casting where selected. Twin-screw reactive extrusion, underwater pelletizing, dewatering and drying can be included as supporting equipment with explicit interface ownership.
Documented acceptance
The proposal defines trials, process records, inspection responsibilities and product-specific acceptance conditions.
Related Project Records and Industry References
Review the evidence type on each record. Haifeng project figures describe their own configuration; public industry references identify third-party sources and are not Haifeng deliveries.
