What are Vacuum Casting/Silicone Molding/Urethane Casting Services?
Vacuum Casting, also known as Silicone Molding or Urethane Casting, is an efficient and versatile manufacturing process that combines silicone molds with a 3D-printed master pattern to produce small batches of high-quality parts in a short timeframe. Each cast part precisely replicates the color, texture, and geometry of the original model, delivering exceptional accuracy and surface finish.This process is perfectly suited for applications such as fit and function testing, marketing samples, concept validation, and high-end prototyping. It is also widely adopted for producing customized end-use parts, especially in low volumes.With the ability to produce between 10 and 1000 flawless plastic components, vacuum casting is an ideal solution for turning your ideas into professional-grade parts—quickly, reliably, and without the high cost of traditional tooling.

Vacuum Casting/Silicone Molding/Urethane Casting FAQs
Vacuum Casting can produce high-quality and sturdy parts, with physical properties comparable to Injection Molding and structurally superior to 3D printed parts.
Compared to Injection Molding, Vacuum Casting has lower costs and is the ideal cost-effective method to create small batch parts. Additionally, the turnaround time is faster for Vacuum Casting than Injection Molding. Vacuum Casting molds are much quicker to make than Injection Molding molds, which can be created by 3D Printing or even by hand, significantly shortening lead times.
Vacuum Casting is widely utilized in industries such as aerospace, automobiles, home appliances, toys, and medical devices. It is particularly suitable for the trial production of small batch samples during the development stage of new products.
There’s no MOQ for Fioria. We offer one-off prototypes and small-batch production. It should be noted that Vacuum Casting is more cost-effective when the quantity is about 5 pieces or more.
Vacuum Casting/Silicone Molding/Urethane Casting Applications
Low-Volume Production
Vacuum casting is an ideal solution for low-volume production, especially when manufacturing plastic parts in quantities from 10 to 1000 pieces. This method offers excellent dimensional accuracy and consistency across every part, making it a reliable choice for high-quality, small-batch manufacturing.
Advanced Prototyping
The vacuum casting process uses low-cost tooling, making it a cost-effective and accessible option for producing high-quality prototypes. It supports a wide range of materials and allows for easy design modifications, enabling rapid iteration and streamlined testing. This flexibility makes vacuum casting an excellent choice for preparing prototypes for functional evaluation and accelerating product development.
Market Testing
Vacuum casting is an ideal solution for consumer testing, user evaluation, and conceptual modeling. It enables the creation of prototypes using materials that closely match those intended for mass production, delivering results that are highly comparable to traditional manufacturing methods. The process accurately replicates the final design’s mechanical and functional characteristics, including surface smoothness, rigidity, and flexibility—making it a powerful tool for realistic product validation before full-scale production.
