CY-IMF-15VSC upper suction casting induction melting furnace is a 15KW induction heating / melting system with MET quality certification and vacuum suction casting device on the top. This unique structural design casts the product (3-5mm diameter alloy rod) by drawing molten metal directly into the top quartz tube. The suction force applied by the vacuum suction casting device can make the melt move quickly to quickly solidify the melt in the quartz tube. This set of equipment adopts suction casting method to cast alloy, which can effectively reduce alloy shrinkage defects, and is an ideal tool for preparing small diameter alloy rods.

Automatic heating time: 1 ～ 99s; Automatic constant temperature time: 1 ～ 99s; Automatic cooling time: 1 ～ 99s
Air cooling: rear fan; protection: automatic water pressure, over temperature and over power protection
2. Vacuum suction casting
The top suction casting device can produce alloy rods with a length of 150mm and a diameter of 3 to 5mm using suction
Using this suction casting method can effectively reduce alloy shrinkage defects
Suction is generated by the rapid movement of the syringe piston (manual operation)
The observation window (Φ12) of the top flange can monitor the melt condition
The quartz tube (7mmOD) × 4mmID × 500mmL) is inserted through the top armor opening for suction casting.
Warning: The temperature of casting alloy should be ﹤ 1200 ℃, so as not to damage the quartz feed tube
3. Graphite crucible & refractory liner & protective cover
The complete refractory liner (5mm thick) made of alumina, including the bottom crucible support, crucible and cover plate.
Include 1.5 ″ OD × 1.25 ″ ID × 3.75 ″ (Deep) graphite crucible
Boron nitride crucible (30 O.D × 24 I.D × 26 H mm) can be provided upon request.
4. Sealing flange & quartz cavity
Stainless steel flange with high temperature silicone O-ring and self-tightening structure
