Sand Casting

Sand casting pouring molten metal into a sand mold. Although not precise, it can be used to manufacture large metal parts at a lower cost or to produce highly complex parts through sand cores.

Aluminum Die casting

The aluminum alloy is melted at high temperatures and injected into the mold under high pressure to cool and form. It is suitable for mass production of aluminum alloy parts with complex shapes.

Zamak Die Casting

Like aluminum die casting, zinc alloys have a lower melting point and can be used to manufacture parts with higher precision and higher complexity and form smoother parts.

Investment Casting

Investment casting, also known as lost wax casting, is a molding process in which a ceramic shell is made from a wax film and molten metal is poured into the ceramic shell.

Gravity Casting

Gravity casting is usually pouring the molten metal into the metal mold, diffusing it in the mold by gravity, and cooling it down. It is suitable for producing small and medium batches of metal parts.

Sand Casting

Sand casting pouring molten metal into a sand mold. Although not precise, it can be used to manufacture large metal parts at a lower cost or to produce highly complex parts through sand cores.
