18 Years Factory Aluminium Gravity Casting - Lost Foam Casting Aluminium Company – RMC Foundry Detail:

Lost foam casting aluminium parts are widely used for transmission cover of heavy duty truck. 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.

Lost Foam Casting, also called EPC (Expandable Pattern Casting) or LFC (Lost Foam Casting), is to put the foamed plastic pattern group coated with refractory coating into the sand box, and fill it with dry sand or self-hardening sand around the pattern. During pouring, the high-temperature molten metal makes the foam pattern pyrolyzed and “disappears” and occupies the exit space of the pattern, and finally the casting method of the casting is obtained.

The castings produced by lost foam casting have high dimensional accuracy and smooth surface with less pollution in the production process. Lost foam casting is a near-net forming process, suitable for the production of more precise castings of various sizes with complex structures and unlimited alloys.
