Bridge The Gap Between Prototype And Production
Vacuum Casting Services For Low-Volume Manufacturing
Create production-quality plastic parts without expensive injection molds. Perfect for functional testing, pilot runs, and small-batch production.
What is Vacuum Casting？
Vacuum casting is a rapid manufacturing process used to create high-quality plastic and rubber parts from silicone molds. It is widely used for functional prototypes, appearance models, and low-volume production, delivering excellent detail, smooth surface finishes, and production-like results.
YD Rapid offers flexible vacuum casting solutions with multiple material, color, and finishing options to support fast product development and small-batch production.

Frequently Asked Questions
What is vacuum casting used for?
Vacuum casting is commonly used for functional prototypes, appearance models, engineering validation, and low-volume production. It is ideal for producing high-quality plastic parts with production-like appearance and performance before investing in injection molding.
What materials can be used for vacuum casting?
We offer a wide range of polyurethane resins that simulate common engineering plastics, including ABS-like, PP-like, PC-like, PMMA-like, rubber-like, transparent, flame-retardant, and high-temperature materials. Material selection depends on your application requirements.
How many parts can one silicone mold produce?
A typical silicone mold can produce approximately 15–30 parts, depending on the part geometry, material, and quality requirements. For larger quantities, multiple molds can be created to support production demands.
Can vacuum cast parts be used for functional testing?
Yes. Vacuum cast parts are widely used for functional testing, design verification, assembly evaluation, and market validation. Many materials offer mechanical properties similar to injection-molded plastics, making them suitable for real-world testing.
What surface finishes are available?
YD Rapid offers a variety of finishing options, including painting, polishing, texture replication, color matching, soft-touch coatings, silk screening, and transparent finishes. Custom surface treatments are also available based on project requirements.
How fast can vacuum cast parts be delivered?
Lead times typically range from 7–15 business days, depending on part complexity, quantity, material selection, and finishing requirements. Expedited services are available for urgent prototype projects.
