Custom PVP ABS plastic parts vacuum casting rapid prototyping service
What is Vacuum Casting?
Vacuum casting, also known as polyurethane vacuum casting process or silicone rubber molding, is a manufacturing process used for producing small to medium quantities of high-quality plastic or rubber parts, primarily for prototyping and low-volume production. This process is often utilized in industries such as product development, automotive, aerospace, and consumer goods.
Key Benefits of Vacuum Casting Process for Rapid Prototypes
|
Quality
| Versatility |
| Vacuum casting process yields excellent quality parts, faithfully replicating even intricate surface details from the original. Thorough preparation of master patterns is crucial. The resulting replicas can be further enhanced through painting, printing, or machining to improve both appearance and functionality.
|
A wide range of casting resins is available, reproducing the appearance, texture, and mechanical properties of standard thermoforming resins like nylon, ABS, or polyethylene. This means there’s no need to compromise functionality for the sake of speed or convenience. Additionally, different types of urethanes can be overmolded to create various surface textures and hardness levels within a single unit.

Vacuum casting rapid prototyping is widely used in various industries, including:
Automotive: For creating prototypes of components and interior parts.
Aerospace: Testing of lightweight and durable parts.
Medical Devices: Production of custom medical equipment and housings.
Consumer Products: Development of prototypes for electronics and household items.
Industrial Equipment: Fabrication of parts for machinery and tools.
Which materials can be used for vacuum casting?
| ABS-like materials |
For parts needing robustness and impact resistance.
|
| Transparent resins |
Used for parts requiring optical clarity, these can mimic clear, glass-like appearances or be tinted for color and transparency variations.
|
| High-temperature resins |
Essential for heat-composed components, offering resistance to elevated temperatures.
|
| Flexible resins |
Provide elasticity for parts that need bending or flexing during use.
|
The main advantage of vacuum casting is that it allows for high accuracy and repeatability, making it an ideal choice for applications where precise dimensions are critical. It also allows for more intricate designs to be cast. However, vacuum casting is not suitable for all applications. For example, it cannot be used to cast materials that are sensitive to heat or pressure.
