Maximum Melting Temperature

3000℃

Copper Crucible

Water-cooled copper crucible with 5 stations (customizable)

Each station: hemispherical cavity, radius 25 mm (customizable)

One station equipped with suction casting device at the bottom

Vacuum Suction Casting Device

Casts metal rods: φ5 mm × L65 mm

By evacuating the copper mold, molten metal is rapidly drawn in, producing rods with minimal shrinkage porosity

Key Features

1. Front observation window + rear LED light for clear arc melting monitoring

2. Water cooling for vacuum chamber, copper crucible, and arc electrode

3. Handwheel-controlled vertical movement with flexible joystick

4. Manipulator flipping mechanism for repeated melting without breaking atmosphere

5. Small, multiple crucibles avoid cross-contamination

6. Bottom suction casting for φ5 mm metal rods
