Vacuum Casting
Vacuum casting is a fast and cost-effective copying technique for producing high-quality plastic parts that are comparable to injection-molded components. Using two-component polyurethanes and silicone molds created from a 3D-printed master, this technique is especially suitable for fit and function testing, marketing purposes, or short series of end-use parts.

技術仕様
Maximum build dimensions | The size of the mold is limited by the dimensions of the vacuum chamber (1,900 x 900 x 750 mm) and by the volume of the product (maximum volume: 10 liters) |
Standard accuracy | ±0.3% (with a lower limit on ±0.3 mm on dimensions smaller than 100 mm) |
Minimum wall thickness | At least 0.75 mm to ensure the mold is filled properly; for best results, wall thickness of at least 1.5 mm is recommended |
Surface structure | High-quality surface finish comparable to injection molding |
