Investment casting is a manufacturing process in which liquid material is poured into a mold that contains a hollow cavity of the desired shape and allowed to solidify.
At Lantian, we offer various casting methods including investment casting, sand casting, permanent mold casting, die casting, low-pressure casting, ESR casting, and lost foam casting, among others. We handle a range of materials including steel, cast iron, and non-ferrous metals.

Machining is a process where raw material is shaped into a final product by removing material in a controlled way.
Lantian operates over 60 high-precision machines, including CNC centers, boring machines, milling machines, and lathes. Additionally, we utilize more than 300 inspection instruments, including three CMMs (Coordinate Measuring Machines) with precision at the micrometer level (μm). We are capable of maintaining tolerances as tight as 0.02mm in repeated production runs.
