Casting Quotation from Gray Iron Lost Foam Casting Foundry – Custom Lost Foam Casting Iron – RMC Foundry

Short Description:

Performance Characteristics of Gray Iron Castings

  • • Liquid gray iron has good fluidity, and its volume shrinkage and linear shrinkage are small, and the notch sensitivity is small
  • • Low comprehensive mechanical properties, compressive strength is about 3~4 times higher than tensile strength
  • • Good shock absorption, the shock absorption of gray iron is about 10 times greater than that of cast steel
  • • Gray iron has low modulus of elasticity

Casting Quotation from Gray Iron Lost Foam Casting Foundry – Custom Lost Foam Casting Iron – RMC Foundry Detail:

Lost foam casting, also called EPS casting or full mold casting, uses expendable mold materials to make the casting mold. At our lost foam casting foundry, we can produce the metal castings by lost foam casting as per your requirements and drawings. The CNC precision machining, and surface treatment services are also available from our factory.

• Tolerances: On Request.

▶ Main Production Procedure
During lost foam casting process, the sand is not bonded and a foam pattern is used to form the shape of the desired metal parts. The foam pattern is “invested” into the sand at the Fill & Compact process station allowing the sand into all voids and supporting the foam patterns external form. The sand is introduced into the flask containing the casting cluster and compacted to ensure all voids and sapes are supported.
• Mold foam pattern making.
• Age pattern to allow dimensional shrinkage.
• Assemble pattern into a tree
• Build cluster (multiple patterns per cluster).
• Coat cluster.
• Foam pattern coating.
• Compact cluster in flask.
• Pour molten metal.
• Extract cluster from flasks.

▶ Inspecting Lost Foam Castings
• Spectrographic and manual quantitative analysis
• Metallographic analysis
• Brinell, Rockwell and Vickers hardness inspection
• Mechanical property analysis
• Low and normal temperature impact testing
• Cleanliness inspection

▶ Why You Choose RMC for Custom Lost Foam Casting Parts?
• Greater design freedom in the construction of cast parts
• Small quantity is possible due to the layered structure of the pattern.
• Lower need for secondary machining with near net shape.
• High flexibility by short start up lead time.
• Longer EPS mould span life, thus lower average tool costs
