What is Vacuum Casting?
Vacuum casting is a rapid manufacturing process used to create high-quality plastic parts by pouring polyurethane resin into silicone molds under vacuum. This technique reproduces fine details from a master pattern with excellent accuracy and surface finish.
Using cost-effective silicone molds and versatile casting resins, vacuum casting delivers parts that closely mimic injection molded components—without the high tooling costs or long lead times.
Advantages Of Vacuum Casting
Here are the key benefits:
- Affordable compared to injection mold tooling
- Fast mold production – Molds can be made in just a few days
- Includes rigid, flexible, transparent, and overmolding resins
- Excellent replication of fine details and textures
- Each silicone mold yields 10+ consistent parts
- Ideal for engineering models, product samples, and pre-production
- Smooth, detailed surfaces ready for finishing and display
- Helps validate designs before committing to mass production molds
When to Use Vacuum Casting?
Vacuum casting is perfect for producing 50 to 300 high-quality plastic parts quickly and cost-effectively, without the need for expensive injection molds. It’s ideal for prototypes, design validation, display models, crowdfunding, and short-run production. With resins that mimic ABS, Nylon, PP, and TPE, it’s also suitable for limited end-use applications and as a bridge to full-scale manufacturing.

Vacuum Casting Surface Finish Options
The following finishes can help you meet the specific appearance, texture, or functional requirements of vacuum cast parts. And ensure that the final parts meet the required specifications and standards.
High-Gloss
Achieved by polishing the master model before mold-making, creating a highly reflective surface. Provides maximum transparency for transparent
Semi-Gloss
Offers moderate glossiness with a balanced reflection rate. Sanding allows for a surface between high gloss and matte, smooth and easy to clean.
Matte/Frosted
Achieved by sandblasting the master model, resulting in a smooth, satin-like surface effect. Ideal for transparent or semi-transparent components, creating a frosted effect.
Textured Finish
Texture is applied to the master model through paint and manual techniques. Improves surface feel, enhances grip, and reduces fingerprint or wear marks.
Custom
Parts available in transparent, black, or custom colors with secondary finishing, painting, or custom finishes. Hardware installation and painting services also available.

Technical Overview: Vacuum Casting
About the Vacuum Casting Process
Vacuum Casting is a rapid prototyping process used to make high-quality plastic parts or products.
Vacuum casting production consists of three main steps:
1. Build a master pattern using 3D printing or CNC machining
2. Build the mold by pouring platinum silicone around master
3. Pour liquid polyurethane resin into mold, create polyurethane casting under vacuum
Vacuum Casting Applications
Ideal for prototypes, presentation models, functional testing, crowdfunding, short-run production, and end-use parts that require high detail and quality without the cost of injection molding.
What is the difference between vacuum casting and traditional casting?
Vacuum casting is different from traditional casting in terms of technology. It is carried out in a vacuum environment, which can reduce the presence of oxygen and other impurities, effectively reducing defects such as pores and inclusions. This makes the castings more uniform, with higher density and more reliable quality.
FAQ's About Vacuum Casting Service

A vacuum casting mold can typically produce approximately 10 to 30 parts. When designing molds, we will try our best to consider improving their service life and efficiency to ensure the production of high-quality parts.
The silicone mold is supported by a rigid outer shell or mold frame that holds its shape during casting and helps maintain proper part geometry as resin is poured under vacuum.
While vacuum cast parts closely mimic the mechanical properties of injection molded parts, they are generally less durable and best suited for prototypes, display models, and short-term functional use.
Vacuum casting offers superior surface finish and material simulation compared to most 3D printing methods, making it ideal for presentation-ready or user-facing components.
