Frequently Asked Questions (FAQs)

What is vacuum casting and how does it work?

Vacuum casting is a manufacturing process that involves creating silicone molds from a master model. Liquid resin is then poured into the mold and placed under vacuum to eliminate air bubbles. This results in high-quality prototypes or small production runs with excellent detail and surface finish. It’s ideal for low-volume production and can replicate complex geometries.

What materials can be used in vacuum casting?

You can use various materials in vacuum casting, including polyurethane resins, silicone rubbers, and even some thermoplastics. The choice of material depends on your project requirements, such as flexibility, hardness, or temperature resistance, allowing you to achieve the desired properties for your final product.

How long does the vacuum casting process take?

The vacuum casting process typically takes a few days, depending on the complexity of your design and the number of parts you need. After creating the silicone mold, the actual casting and curing of the resin can usually be completed within a few hours, but the entire project timeline may vary based on preparation and finishing requirements.

What are the benefits of using a vacuum casting factory?

Using a vacuum casting factory offers several advantages, including cost-effectiveness for low-volume production, quick turnaround times, and the ability to create highly detailed and accurate prototypes. It also allows for easy modifications to designs, making it a flexible solution for product development.

Is vacuum casting suitable for production runs?

Yes, vacuum casting is suitable for short to medium production runs. While it’s not as efficient for large-scale manufacturing as injection molding, it’s perfect for producing small quantities of parts or prototypes. This method allows for rapid iteration and testing, making it a great choice for product development cycles.
