Title preview
Stay on an RTV mold until labor, sag, or chemistry force a change. Volume alone is not the switch. Recast and duplicate first; steel LSR is a parts quote.

An 8-cavity RTV tray does not cut dump price by eight. It cuts pour time per piece and raises jacket, sag, scrap, and recast. Run the dump math.

FAI on an RTV mold is a packet: ballooned drawing, fill-weight, Shore, jacket, and visual. It is not a photo of a nice dump. State wait and trim.
Read article -Remote audit of an RTV mold shop is a timed shot list: vacuum bench, mix, pattern, resin mother, jackets, metrology. If you cannot name the shots, you are touring.

You cannot NDA a master into secrecy. Make copying expensive: watermarked files, custody of the pattern, no-export, recast rights, and photos of your

An RTV mold pays for itself when trim, sag scrap, and recasts stay below a steel jump you may not need. TCO is stack plus conversion, not piece vs mold

Precision RTV kits fail in transit packed as cargo: crushed skins, cracked support shells, warped living mothers. Crate the kit dry, blocked, and nested.

You can recast an RTV skin on the same living mother. A geometry change means a new mother, then a recast. Budget add vs subtract on the pattern, not a weld.

RTV prototype time starts at CAD lock, not the first email. Cut calendar by unmixing RTV vs LSR, finishing the pattern, and not cutting steel first.
