천공 스테인리스 스틸 주형 플라스크 (4" x 8 1/2", 플랜지형) - 대형

The machining on these flasks is noticeably precise—each perforation lines up exactly as it should, making the draw consistently smooth. I've run three casts already and the results are cleaner than with my old setup. Definitely worth the upgrade for anyone doing serious work.

I was a little worried about the perforations clogging with fine casting material, but they’ve been flawless so far. The machined edges fit my flask holder perfectly, and the draw on these 4" x 8 1/2" flanged models is noticeably cleaner than my old solid ones.

These flasks have completely streamlined my burnout process—the stainless steel holds up to repeated heating without any warping. The flanged edge makes handling with tongs much more secure, and the tight tolerances mean the fit in my kiln is exactly what I needed.
