Vaccum Comparison Casting Machine

Flawless Casting with Dual-Force Technology The Imtex Vacuum Pressure Casting Machine is engineered for jewellery manufacturers who demand perfection. Unlike standard vacuum casting, this advanced system utilizes “Active Overpressure” technology.

By combining powerful vacuum suction at the bottom of the flask with inert gas pressure from the top, the machine “compresses” the molten metal into the mold. The result is a casting with extraordinary density, finer surface detail, and zero porosity. It is the ultimate solution for stone-in-place casting and difficult filigree designs where standard gravity or simple vacuum methods fail.

Jewellery vacuum casting system

Key Features

  • Dual-Force System: Simultaneously pulls a vacuum to remove air and applies inert gas pressure (Argon/Nitrogen) to force metal into every crevice of the mold.

  • Oxidation-Free Melting: The melting chamber operates under a vacuum/inert gas atmosphere, ensuring the metal remains pure and free from oxidation (blackening).

  • Electromagnetic Stirring: (Optional) Inductive heating automatically stirs the metal, ensuring a homogeneous alloy mix before pouring.

  • Smart HMI Interface: Features a touchscreen PLC display for saving casting programs (time, pressure, and temperature profiles).

  • High-Speed Pouring: Automated tilting and pouring mechanism ensures consistent speed and prevents metal cooling during the transfer.

Ideal Applications

  • Stone-in-Place Casting: The pressure ensures metal flows around stones securely without thermal shock.

  • Filigree & Micro-Pave: Captures the sharpest details that standard machines miss.

  • Mass Production: Consistent weight and density reduce gold loss during polishing/finishing.
