THE PERFORMANCE STANDARD
FOR PRODUCTION CASTING!

INDUCTO-VAC® 10KW
CASTING SYSTEM

Memco's Inducto-Vac 10KW
  • RAPID INDUCTION MELTING
  • PRECISE VACUUM CASTING
  • REDUCE REJECTS
  • REDUCE FINISHING
  • INCREASE PRODUCTIVITY
  • LOWER OPERATING COSTS
  • RELIABLE PERFORMANCE
  • RUGGED, DURABLE
The Memco Inducto-Vac Casting System provides precision control of the investment casting process along with high production of perfect castings at a much lower initial cost and much lower operating expenses than any other induction casting machine.

Improve quality and eliminate rejects through precision control of temperature and many other process variables.

Reduce finishing time because castings have better definition of contours and detail and better polishing properties than centrifugal castings.		 Increase production because casting is instantaneous - no waiting on a centrifuge.  The crucible is stationary, insulated, and not cooled by spinning.  Less heating is required, melting is faster and less energy is used.

Lower operating costs due to the inherent long life and high efficiency of the solid state heating unit, the very high thermal efficiency of new materials, and the longer life of the refractories.

All these benefits and more are possible with the Memco Inducto-Vac because of the creative technology incorporated into this compact unit.
 
PERFECT CASTINGS
Memco Genuine 1000cc Crucible CERAMIC CRUCIBLES
Memco has used bottom pour ceramic crucibles in our machines for over 15 years.  The unique Memco ceramic crucible offers many advantages over common casting crucibles, all of which can help you make more profit.  The very large 1000cc capacity crucible means you can cast many more pieces per flask.  This increases your productivity by enabling you to cast once what might have taken you two or three castings to complete.
 
  • Completely inert to prevent chemical interaction and contamination of the molten metal.
  • Durable ceramic crucibles have a much longer life than carbon crucibles because they do not oxidize, or crumble and fall into the flask.
  • Bottom pour arrangement helps insure that clean metal enters the flask first.  Any dirt or residue goes into the button.
  • Bottom pour arrangement assures maximum operator safety in pouring molten metal due to very short distance poured.
  • The precision pour hole design does not enlarge or change shape with age.  This feature carefully controls the pour rate to minimize turbulence and reduce defects in the casting.
  • Electrically transparent ceramic allows metal to be constantly stirred through induction currents.
  • Off center mounting of the valve rod provides clear area to load large metal pieces and stir the metal.
 
VACUUM CASTING

This is the ONLY way to provide a uniform force on all metal surfaces.  The vacuum eliminates all gases and insures proper filling.  Vacuum castings are free from voids, surface roughness and distortion common to the unidirectional force of a centrifuge.
 
FLEXIBLE FLASK OPTIONS
Memco 11 gauge Stainless Steel Flasks
 
No need to retool your shop and your casting process to accommodate this machine.
 
    Perforated Flask
  • Excellent form filling of even the most challenging designs is achieved in larger flasks without special techniques.
  • Our flask chamber accommodates most popular sizes of flasks up to 6" Ø by 12" H.  Large flask accommodations are available by special request.
  • The precision design of the flask chamber and gasket engineering provide superior sealing and vacuum.
    Standard Flask (non perforated)
  • The Electro-Vac can be fitted with optional flask adapters to enable you to use your current non perforated flasks.
    Ingots
  • Strip and wire ingots can also be easily poured using standard molds.
ACCURATE METAL TEMPERATURE

Accurate, reliable casting temperature is very important to the process.  Some alloys can tolerate only a few degrees error.  Memco uses an immersion thermocouple in the bottom of the valve rod to directly measure the metal temperature.  This bottom location gives accurate measurement regardless of the amount of metal.

The automatic control system alerts the operator to get the flask into the vacuum chamber and reduces the power output as it approaches the desired temperature.  This power reduction slows the temperature rise rate to allow precise temperature control by the operator.  The operator may vary the power level to fit the required casting procedures.
 
GAS SYSTEM

Automatic gas control system assures the melt is protected at all times.  Reducing gas will remove oxides from the molten metal as it is stirred by the low frequency currents.  The gas system is not pressurized thereby eliminating the gas tight melting chamber and attendant problems.
 
HEATING UNIT
  • Indirect heating of the unique ceramic crucible/susceptor arrangement eliminates burning the metal.
  • Powerful, low frequency currents stir the metal to ensure a homogeneous alloy and assist in removing oxides trapped in the metal.
  • Solid state generator provides excellent reliability and long life contrasted to short lived, expensive vacuum tubes.
 
SIMPLE, RAPID OPERATION

The completely automatic power control system eliminates complex adjustments.  The controls are few and clearly labeled.  Advanced thermal design permits rapid warm up and cool down.  Simultaneous melting while previous pour solidifies in flask under vacuum speeds production.  The operator can load metal and flasks easily.  All these features result in much higher production than other machines.
 
VERSATILE OPTIONS

Shot in Bucket
The Inducto-Vac has several options to configure a system for your particular requirements.  The shotting/alloying system is a useful option for those wishing to alloy their own gold and make shot.
ECONOMICAL

The low initial cost for the complete system is only the beginning of economy.  The advanced electrical and thermal designs insure low power consumption and less heating of the casting room.  The space saving design and light weight permit the unit to be easily placed anywhere by two men.

PRACTICAL

The Inducto-Vac uses standardized parts for quick replacement.  All parts and supplies are available overnight from the factory.  Our staff is ready to help you in all phases of the investment casting process.		 Ring Tree
