Product Update: New Cast Urethane Materials and Finishes Available for Instant Quoting

We’ve expanded our available materials for urethane casting, one of our favorite low-volume manufacturing technologies. Urethane casting is used to make end-use, highly durable, parts with robust mechanical properties. It is considered a “soft-tooled” process, where a silicone mold is formed around a master pattern--usually 3D printed. The mold is used to create casted copies of the pattern out of polyurethanes that are customized to hit performance, color, and hardness requirements.

In this blog post, learn about and compare our new polyurethanes to find the best fit for your project. These urethane casting resins boast a range of performance, color, and hardness properties to fit any application. Because urethane casting is often a bridge production method before moving to injection molding, we describe our urethanes in terms of common molded materials.

Xometry urethane casting service has materials in two main durometer classes, rigid (Shore D) and rubber-like (Shore A). Urethanes can be custom colored and finished to match your specifications.

Rigid Polyurethanes

Black, Natural, Color-Match options:

• ABS-Like, FR: A tough, flame-retardant material with a robust Shore D 80 hardness
• General Purpose: An impact-resistant urethane at Shore D 78 hardness. This is used for a wide variety of applications.
• Glass-Filled Nylon-Like: A stiff, high-performance urethane at Shore D 85 hardness. This material meets USP Class VI standards.
• Polypropylene-Like: A tough, abrasion-resistant, and somewhat flexible urethane with a slightly softer Shore D 65-75.
• Polycarbonate-Like: A stiff, high-impact, high HDT material at Shore D 82-86 hardness with a wide variety of uses. 

Clear option:

• Rigid Clear Polyurethane: A versatile, clear material at Shore D 80 hardness. Using a matte finish leaves a frosted look while using a high-gloss finish will give the highest clarity.

Rubber-like Polyurethanes

• Rubber-Like Polyurethanes (Black, Natural, Color-Match): We have seven varieties, ranging from Shore A 30 to Shore A 90, with high elongation to break and high durability.
• Clear Rubber-Like Polyurethanes (Colorless): We have four varieties, from Shore A 45 to Shore A 90, that have excellent clarity and high elongation to break.

Custom Polyurethane

As always, Xometry can custom source and match specific urethane properties. We can even quote overmolding and insert molding applications.

Additionally, Xometry now has the following finishes available for cast parts:

• Matte/Frosted
• Semi-Gloss
• High-Gloss
• Custom

You can get an instant online quote on any of these materials and finishes through Xometry Instant Quoting Engine℠ (View instructions below). Tooling is included in the part pricing. You can also learn more about Xometry’s urethane casting service.
