Urethane Casting

Urethane Casting for Precision Optical & Industrial Components

We focus on urethane casting for optical components, covering resin urethane casting, soft urethane molding, and high-precision urethane parts processing, fully matching the needs of AI vision, drone inspection, ADAS and other high-demand scenarios.

Core Urethane Casting Services

Custom Urethane Prototyping: Fast lead time, support small-batch trial production, match the size and performance requirements of optical equipment, and assist in R&D iteration.

Resin Urethane Casting: Suitable for high-precision optical mounts, camera shells and sensor brackets, with stable performance and consistent quality, ensuring tight fit with optical components.

Soft Urethane Molding: Flexible and wear-resistant, suitable for outdoor drone equipment and industrial inspection parts, effectively reducing light reflection and improving imaging clarity.

High-Precision Urethane Casting: Strictly control the thickness of urethane layer, adapt to the working environment of high temperature, humidity and outdoor exposure, and meet the long-term use requirements of automotive ADAS.

Applications: Gaskets, Medical Pads, Insulation

Urethane Casting Materials

Polyurethane is a widely used thermoset material grouping known for its strength, durability, abrasion resistance, and versatility. Different urethanes can mimic the properties of many common thermoplastics. For example, a stiff urethane cast part is “polycarbonate-like,” and a more flexible plastic may be “polypropylene-like.” We group our urethane materials into general categories to help you make quicker decisions and get the best performance on your project. The list below describes the categories of materials and technical examples when selecting polyurethanes.

Materials Offered

General-purpose, rigid clear, ABS-like, PC-like, PP-like, nylon-like, rubber‑like, and clear rubber‑like polyurethanes with various shore hardness.

Note: Equivalent materials may be used based on availability.

Applications of Urethane Casting

Low-Volume Production

Urethane cast parts are perfect for low-quantity production—when volumes do not justify investment in injection mold tooling—as well as for first run production parts, which can be completed weeks before production tooling is ready.

Advanced Prototyping

The urethane casting process and relatively inexpensive tooling involved makes it easy and economical to make any necessary design changes. Additionally, different materials can be used with the same mold, making it possible to test designs with a variety of materials

Market Testing

End-user functionality and a high-quality finish makes urethane cast parts ideal for consumer testing, user evaluation and concept models. Using the cast urethane process means that changes can be incorporated quickly for either further testing or market launch.
