Vacuum Casting Standard

Urethane casting (also known as RTV molding, cast urethane, and silicone molding) is a fabrication method that uses silicone molds to produce production-grade elastomeric parts with 10-200 units.

Typical lead time Up to 20 parts in 15 days or less, depends on the part specification and volumes.
Accurate ± 0.3% (with lower limit on ± 0.3 mm on dimensions smaller than 100 mm)
Minimum wall thickness To ensure that the mold is filled properly, a wall thickness of at least 0.75 mm is necessary. For best results, we recommend a wall thickness of at least 1.5 mm
Maximum part dimensions The size of the mold is limited by the dimensions of the vacuum chamber (1900 x 900 x 750 mm) and by the volume of the product (maximum volume: 10 liters)
Typical quantities Up to 25 copies per mold (depending on the mold’s complexity and the casting materials)
Color & Finishing Pigment is added to the liquid polyurethane prior to casting, custom painting and texture.
