A Comprehensive Guide to Vacuum Casting Services in China
Vacuum casting, also known as urethane casting, is a rapid prototyping and low-volume manufacturing technique widely used in China. This process offers a cost-effective and efficient method for producing high-quality prototypes and small production runs of plastic parts. This guide explores the intricacies of vacuum casting in China, highlighting its advantages, technical specifications, material options, and prominent service providers.
Understanding the Vacuum Casting Process
Vacuum casting involves creating a silicone mold from a master pattern (often produced via CNC machining or 3D printing). This mold is then placed under vacuum to remove air bubbles. Polyurethane resin is subsequently poured into the mold, filling the cavity and solidifying to create a part that accurately replicates the master pattern. The vacuum ensures a bubble-free, high-quality final product. Companies like www.in3dtec.com excel in this process, offering quick turnaround times as fast as 3 days.
