Casting is a process where molten material is poured into a mold and allowed to solidify, taking the shape of the mold.

Lantian provides diverse casting methods, including investment casting, sand casting, permanent mold casting, die casting, low-pressure casting, ESR casting, and lost foam casting. We specialize in casting valve components, using materials like carbon steel, stainless steel, and non-ferrous alloys. We handle parts with weights ranging from 0.01kg to 150 tons.

Machining involves the removal of material to shape it into the desired form.

We provide detailed weekly reports with photos and videos, and maintain full inspection documentation. We also serve as third-party inspection representatives for clients whose products are made by other suppliers.
