Cast Polyurethane vs. Injection-Molded Polyurethane Screen Panels: What's the Difference?

Cast Polyurethane vs. Injection-Molded Polyurethane Screen Panels: What's the Difference?

The core difference lies in the material used and the manufacturing process, which ultimately affects the panel's wear life, performance, and cost structure.

Here's a comprehensive comparison to help you choose the right polyurethane screen panel.

Key Distinctions

Feature	Cast Polyurethane	Injection-Molded Polyurethane
Material	Thermoset (irreversible)	Thermoplastic (re-meltable)
Key Attributes	Superior abrasion resistance; wider hardness range	High production speed; excellent dimensional consistency
Manufacturing	Pour liquid into molds; slow curing (~35 min)	Inject molten plastic; fast cycle (~5 min)
Mold Cost	Lower	Higher
Per-Part Cost (high volume)	Higher	Lower

Performance & Wear Life

Cast Polyurethane: Lasts 1.5 to 2 times longer than injection-molded in abrasive conditions.
The Game Changer: LANXESS and Autox developed a process allowing cast-grade PU to be injection molded—lasting up to 3× longer.

Cost & Production Efficiency

Cast: Lower mold costs; slower process; higher per-part cost
Injection-Molded: Higher upfront mold costs; fast production; lower per-part cost for high volume

Summary Recommendations

Priority	Recommendation
Maximize wear life in abrasive conditions	Cast Polyurethane
High volume, tight tolerances, complex geometries	Injection-Molded
Both superior wear life AND production efficiency	Advanced Injection-Molded Cast PU
