Vacuum casting is a well known casting technology to produce high quality prototypes, small-batch functional parts, etc. It is mainly used in the field of rapid prototyping and low volume production. This process requires the main products to make prototypes. It is a cost effective process and it does not require mass production to save the cost.

Why choose Sunray Precision Prototype as your vacuum casting service provider?

• Highly accurate dimensional design

All of our vacuum casting products are accurate and have a very accurate design. The surface finishing is clean and they have a polished appearance. Another good thing about our vacuum casting service is we provide high quality dimension precision. The casted parts maintain the correct dimension and tolerance according to the original pattern. Minimal deviation ensures that the parts can fit and function properly.

• Highest quality prototyping material

We use high quality material in making our prototypes, which is essential for achieving the best results. The molds used in the process are highly durable to withstand the casting temperature. It is important for consistent and accurate results. The high requirements for quality have also won us the unanimous approval of customers。
