The technology

Vacuum casting allows the duplication of parts in small or medium series with low stroke and good flexibility.

This process is carried out in two steps. First, silicone is cast around the part of interest in a pressurized chamber. Once hardened, a mold is obtained. In a second step, a resin is injected under vacuum into this mould to form by hardening the desired part.

The pressurized chamber allows you to remove the microbubbles present in the silicone or resin during their shaping, and thus obtain parts without porosity.

The vacuum casting technology makes it possible to use many different resins for all your prototypes with technical characteristics similar to injected plastics (PP, PA, PVC, PEEK etc.). Many rigid and flexible resins are available: transparent, coloured, resistant to fire, folds, shocks…

CSV 340 Multicool

The 340-MULTICOOL is a small and medium capacity manual vacuum casting machine which allows the operation of molding up to L 340 x L 340 x H 435 mm and with a casting volume up to 600 ml.

The 340-MULTICOOL is ideal for didactic applications, as a first machine or as a complementary machine. Equipped with a fully glazed door and high-performance lighting, it makes it possible to clearly visualize the entire process in order to perfectly control the casting. The mixer speed and chamber pressurization are also controllable and adjustable.
These vacuum casting machines equip the main rapid prototyping centres in Europe.

They allow a very fast vacuum, which is a plus when using preheated moulds.
