Precision casting service refers to a group of metal casting processes capable of producing dimensionally accurate metal parts with tighter tolerances and better surface finishes than conventional casting methods. The tolerance standards achieved depend on the specific casting process used. This article mainly discusses the tolerance standards of precision casting services that Neway can provide and can be achieved, including die casting, sand casting, and investment casting. Investment Casting Tolerance Standards Investment casting service is considered one of the most precise casting processes, capable of tight tolerances down to ±0.005 in (±0.13mm) or even tighter for small castings under four in2. For larger castings, the typical tolerance range is ±0.015 in (±0.38mm) or ±0.5% to ±1% of the nominal dimension. The wax pattern used in investment casting can be formed to exact dimensions, creating an accurate mold cavity in the ceramic shell. The ceramic shell withstands the fo...
