Urethane Casting Tolerance
Urethane casting is a fabrication process that uses silicone molds to produce production-grade elastomeric parts with 10-200 units. Typically ISO 2768-m is used as manufacturing standard and a shrinkage rate of +0.15% can be expected due to thermal expansion of the liquid, and the response of the flexible mold.

FAQs About Urethane Casting Service
What is the lead time for urethane casting?
Production-level urethane casting typically has lead times of 3 weeks. Although the master pattern and mold can be finished in 1-2 days, meeting production volumes can take longer due to the urethane’s curing time, which cannot be shortened. A single urethane casting mold usually produces 1-10 parts per day, depending on factors like the type of urethane and part geometry.
How does urethane casting work?
Urethane casting is a manufacturing process that involves creating a mold using a master pattern or model, typically made of silicone rubber. A mixture of urethane resin and a curing agent is then poured into the mold cavity, ensuring it is filled completely and that any air bubbles are removed. The urethane is left to cure at room temperature or in an oven, and once it has hardened, the mold is opened, and the cast part is removed and trimmed of any excess material.
What are the tolerances for urethane casting?
The tolerances of cast urethane are usually approximately ± 0.015” or ± 0.003 per inch, whichever is larger. On a case-by-case basis, tighter tolerances might be provided. Generally, a typical shrinkage rate is +0.15%.
What is the difference between urethane casting and injection molding?
Urethane casting uses liquid urethane resins that are poured into a mold, while injection molding uses molten plastic that is injected into a mold. Urethane casting molds are typically made of silicone rubber or other soft materials, while injection molding molds are made of steel or aluminum and are much more durable. Urethane casting is suitable for low to medium production volumes, while injection molding is better suited for high-volume production. Additionally, injection molding can produce parts with more consistent dimensions and tighter tolerances, but the upfront costs for tooling are much higher.
