Process Difference between (v-LFC) Vacuum assisted Lost Foam Casting Process & Replicast (Building Shell like Lost Wax)

Vacuum Assisted Lost Foam, Replicast and Full Mold Process for Castings of metals are modern Environmentally Friendly and Most Economical Moulding and Casting Process today.

Vacuum assisted Lost Foam Casting, V- LFC Process for Foundries

Most Cost Effective Foundry Process Today


Operating Old Foundries eats away our profit margins as they are not Energy Efficient and technologies and process being followed are mostly obsolete.
Don't Bleed Profits into Depreciated & Old Foundries.
Keep Modernizing!



If the casting is coreless your savings could be about 25% and with cores the savings could be to the tune of 40%



Today sand conservation is not only environmental issue, but a cost to all the existing foundries. Preparation of moulding sand, with Chemical and Natural additives and reclaiming the same sand between 70% to 90% is a capital intensive process with day to day operational cost and maintenance cost.
The only answer to this is adopting V-LFC process for casting, by Ferrous and Non-Ferrous Foundries.
Highlights of V- LFC Casting Process:

  • No Rejections due to Core Shifting, as no cores needed
  • No Fins so almost nil fettling
  • Faster Delivery, because of almost nil after work and thus edge over competitors and satisfied customers.
  • Machining work minimized
  • Weight of castings are reduced, as draft-angles not needed
  • Intricate parts can be cast
  • Most economical molding process for < 300 kg castings
  • Sand reused with almost nil wastage (spillage & dust formation max 1%)
  • Environmentally friendly and friendly to workmen, as no chemical additives needed
  • Most Economical Moulding Process today
  • No Core, so no Core cost
  • Moulding cost is reduced
  • Finishing cost is almost nil
  • Very good Surface Finish


The surface finish is so good that no other casting process can achieve, at cost of LFC. This open avenues for getting better price.
