Polyurethane Casting
Injection-molded quality delivered fast in small batches. Xinda casts polyurethane in silicone molds under vacuum, with material properties close to mass-produced parts, ideal for 10-50 piece production runs.
Process Overview
Polyurethane Casting
Cast part quality depends on material selection and pouring control.
- Material guidance: our engineering team recommends materials by application to avoid mismatches
- Samples first: confirm results with cast samples before committing to batch production
- Ready-to-use delivery: finishing and assembly coordinated so parts work out of the box

PU Casting in Prototype Making
- Injection-Like Results PU casting simulates injection molding with material properties close to mass-produced parts.
- Fast & Affordable No injection mold needed; low cost and fast delivery for small batches.
- Material Options ABS-like, PP-like, clear, rubber-like, and more polyurethane options available.
- Good Surface Quality Cast parts have smooth surfaces with painting and silk screening available.
PU Casting Advantages & Process
Polyurethane casting uses silicone molds to pour PU resin in a vacuum environment. It simulates injection molding results at a fraction of the cost, ideal for small batch (10-50 parts) production.
Xinda offers ABS-like, PP-like, clear, rubber-like, high-temp, and more PU material options. Cast parts are dimensionally stable with good surface quality for functional testing, appearance validation, and low-volume delivery.
