Vacuum casting, also known as urethane casting, is an excellent solution for producing high-quality prototypes and low-volume parts that closely mimic injection-molded components. The process uses silicone molds and liquid polyurethane resins to create parts with exceptional detail, smooth surface finishes, and reliable mechanical properties.
It’s perfect for functional testing, market validation, and short-run production, offering a cost-effective alternative to traditional molding. With tight tolerances (±0.1 mm) and lead times as fast as 5 days, vacuum casting delivers precision, durability, and design flexibility across a wide range of industries — from automotive and consumer products to electronics and medical devices.
Bludeek’s urethane casting solutions support every stage of your product development — from prototype testing and functional validation to market-ready production. Operating through ISO-certified facilities and trusted manufacturing partners, we ensure your projects stay on schedule and within budget.
We produce high-quality urethane parts with tolerances up to ±0.10 mm and lead times as short as 5 days. Choose from a wide range of polyurethane and silicone materials, surface finishes, and color options tailored for industries such as automotive, electronics, and consumer products.
Achieve tight tolerances from ±0.1 mm to ±0.8 mm with exceptional surface finishes. Our advanced mold-making process guarantees accuracy, consistency, and superior part quality every time.
Select from a wide range of soft, rigid, transparent, or flame-retardant polyurethane materials. We’ll help you choose the best material, finish, and color to match your specific design and performance requirements.

Vacuum-cast parts can achieve high precision, with tolerances typically up to ±0.10–0.15 mm, depending on part geometry and size.
Urethane casting is highly cost-effective for low-volume runs, as it avoids expensive tooling and setup costs associated with injection molding.
Vacuum casting produces more durable, functional parts with better surface finish and material properties, while 3D printing excels at rapid prototyping and complex geometries.
Silicone molds used in vacuum casting are durable for multiple castings, typically producing 20–50 parts per mold, depending on material and complexity.
Molds are secured using clamping frames or jackets, ensuring proper alignment and preventing leaks during the casting process.
