What Is Urethane Casting?

Urethane casting uses a softer silicone mold in comparison to the harder machined molds used in injection molding. The process produces urethane materials that may be rigid or flexible. Urethane molding is a fast fabrication process that can create complex parts, components, and tools with the use of detailed silicone molds. These silicone molds may be simple or incorporate complex design geometries.

Vacuum casting is a low-cost but reliable method for making a small number of high-quality prototypes based on a master model. This method is ideal for rapid prototyping used in engineering testing, proof-of-concept and display demos. On superior prototype, we have a dedicated team of mold makers who are experts at creating vacuum casting molds for many years.

Low initial cost since it no need to invest in tooling

●  The high fidelity of the mold gives excellent surface details requiring little or no post-processing

Many different molding polymers are available that can be pigmented to meet your color requirements

Molds can be ready in a few days once the master model has been created

Molds are durable up to approximately 50 copies so it’s great if you need more than one copy

We provide overmolding, so that different types and hardness of plastic can be molded together into a single unit

It is an excellent option for testing multiple variations of a prototype design for rapid product development

Urethane Casting Materials

Careful material selection is an important part of the design process. A variety of polyurethane materials can be used in urethane casting. Material selection depends largely on the desired physical properties of the end part. In addition, additives can be added to most materials that result in different colors, finishes, and textures.

1. Elastomeric (Shore A). Shore A urethane-based materials are soft and flexible.

2. Rigid (Shore D). This classification of material is rigid. It creates impact-resistant and rugged products.

3. Expanding Foam. Foams can range from soft and low-density to high-density and rigid.

4. Silicone Rubber. These composite materials are usually platinum-based and are used to form small high-contact parts.

Various materials and additive mixtures can be used to meet a variety of industry standards, such as UL 94-VO and FAR 25.853 ratings regarding flammability, flame exposure, and exposure to high temperatures or the cleanliness standards found in many pharmaceutical and medical applications

Urethane molding is a popular fabrication process across multiple industries because it produces durable, affordable parts quickly.

The following industries commonly use urethane casting:




 Consumer products

 Dental and medical
