What is Lost Foam Casting?

Lost Foam Casting (LFC) is a casting process which using a polystyrene foam pattern imbedded in traditional green sand. The polystyrene foam pattern left in the sand is decomposed by molten metal. The molten metal replaces the foam pattern and precisely duplicates all of the features of the pattern.

Advantage of Lost Foam Casting

The lost foam process holds unique advantages over other manufacturing and casting processes.
1. Neither additives, binders, nor cores are required.
2. Once installed, lost foam casting offers flexibility in casting design and is environmentally friendly.
3. Scrap volumes are minimized; the equipment’s footprint is small; energy and manpower requirements, as well as insurance premiums are reduced; as are the machining and finishing requirements.
Application Field
Manufacturing Process
1. Pattern making:design and make pattern according to our customers’ samples or drawings by cooperated mould factory. 2. White foam model making:fill the mold cavity with EPS bead and heating so that make the bead again filled the space between beads to form a smooth surface.Take out the foam model after cooling. 3. Coating:stick foam molds to the riser to become a model cluster and coat with fireproof paint,then dry the model cluster in the 45-50℃ baking room. 4. Put some sand into box first to reach thickness 100~150mm and then place the model cluster in the sand,pour sand again to fully cover and seal the box totally. 5. Vacuate the box and pouring metal liquid,in this case EPS model will gasify in the fuction of metal liquid, gasification gas will through coating sand enter negative pressure system,the metal liquid will replace the position of EPS model and finally form lost foam castings,whose dimensions will be the same with EPS model. 6. Pour out the sand and model cluster,cut the castings from cluster,,put all the formed lost foam castings into the shot blasting machines to make surface smooth. 7. Test the finished lost foam castings and prepare for delivery to customer’s destinations after package.

1.What size range of parts can be produced by the lost-foam process?

Lost-foam castings can be produced in most all metals from a fraction of a Kilogram up to several TONS. Slightly more advanced techniques are used for very large castings.
2. What is the cost of using the lost-foam casting comparing to other process?
Lost-foam castings are generally more expensive than forged parts, or parts made by other casting processes. The value inherent in the lost-foam process versus other processes is seen in tighter tolerances, weight reduction and as-cast features which all results in less machining and cleanup time. Many castings that require milling, turning, drilling and grinding can be made in the lost-foam process with only 5-8 mm of machine stock. It is imperative that the features to be cast are discussed by all parties
to determine the net finished product cost.

3. What type of surface finish can be achieved for lost-foam casting?
Because a permeable refractory coating is applied around the smooth foam pattern, the resultant finish is excellent. Each casting facility is different, but generally lost-foam process castings have a surface finish within the 60-250 RMS range. If surface finish, due to cosmetic requirements, is a critical issue then surfaces can be targeted to maintain an exceptionally smooth finish.

4. Are there porosity or shrinkage problems for lost-foam casting?
Lost foam castings are used in many critical applications in automotive, construction, heavy truck, railroad and marine applications. The process has fewer gating and feeding restrictions, and casting soundness is normally easier to achieve than with traditional molding methods.

5. What type of tooling is required for lost-foam process?
Typically, tooling is composed of a split-cavity machined aluminum die that is the negative mold from which the foam pattern is produced. The tooling is highly specialized and must be constructed by experienced tooling manufacturers familiar with the requirements of the foam molders and foundries. Most tooling for lost-foam process patterns will compare favorably with permanent and Die Cast tooling. Prototype and simple tools may be in the few thousand Rupees range while high-end tooling for complex or very large parts can be in the several Lack Rupees range. As a result of the materials used and the process stresses, lost-foam process tools can be expected to have 3 to 4 times the cycle life of permanent mold or die casting tools.
6.What materials can be poured as a lost foam casting?
Commonly cast metals include cast irons, aluminum alloys, steels, and nickel alloys. Less frequently cast metals include stainless steel and copper alloys. Metal pouring temperatures of at least 1000 degrees F are usually required to decompose the lost foam patterns and gating systems.
