Frequently Asked Questions (FAQs)

What is the vacuum casting process, and how does it work?

?

Vacuum casting is a method for producing high-quality prototypes or low-volume parts using inexpensive silicone molds. Here’s a quick rundown: First, a master model is created using 3D printing or CNC machining. Then, liquid silicone is poured around the model to create a mold. Once the mold is ready, a polyurethane resin is mixed, vacuumed to remove air bubbles, and poured into the mold. After curing, the part is removed and may be trimmed or sanded for a final finish.

What kinds of materials can be used in vacuum casting?

?

You have a wide range of materials to choose from when it comes to vacuum casting. These include materials similar to ABS, PP, PC, and rubber, as well as transparent and colored options. For example, you can get materials with heat resistance up to 90°C, high impact strength, and various Shore hardness levels for rubber-like parts. The materials can be customized to match specific colors and finishes, making it versatile for different applications.

What are the advantages of vacuum casting for my project?

?

Vacuum casting offers several benefits. It allows for low-cost molds and quick turnaround times, often as fast as 3 to 7 working days. You can produce parts with high quality and a production-like finish, which is ideal for pre-launch product testing, concept models, and low-volume production. Additionally, it supports a wide range of materials and customized surface finishes and colors, ensuring part consistency and thin-wall casting capabilities.

Why should I consider outsourcing vacuum casting to China?

?

Outsourcing vacuum casting to China can be highly beneficial. You can take advantage of significantly lower labor costs and material prices, which can help reduce your overall production expenses. Chinese manufacturers often have access to state-of-the-art technology and a large workforce, ensuring timely production and high-quality results. This allows you to focus on other aspects of your business while experts handle the manufacturing process.

How many parts can I produce with a single silicone mold?

?

A single silicone mold in vacuum casting can typically produce around 20 to 25 accurate parts before its accuracy is compromised. This makes it an efficient method for low-volume production. After the mold reaches its limit, you can easily create a new mold to continue production, ensuring consistent quality across all your parts.
