LFC production line is also called full mold casting that is a new type casting method. The foam model who has the same size as casting will be painted with refractory material and dry, then bury in the dry quartz sand or ceramsite, forsterite sand to vibrate the model, and then pour under the negative pressure, making the foam model gasified, the liquid metal hold the model position, then form the casting after cooling solidification. LFC technology is known as the "green revolution of foundry industry ".More>>

vacuum sealed molding process is called V-process for short. It combines vacuum technology with sand casting, adopts the single dry sand to seal the mold cavity surface and back by plastic film, then use vacuum pump suction to produce negative pressure, causing the differential pressure within and outside the sand mold, making the sand mold tighter then forming cavity. This process belongs to a physical modeling method.More>>
