Title preview
Kitchen and food mold production here is pattern, often a flip, production master, then batch RTV. Finished kitchenware goods may sit an HTV product or mold RFQ here, or a different LSR-tool RFQ - ask us.

Name the market first. US repeated-use rubber is 21 CFR 177.2600. Germany adds LFGB and BfR XV. Factory ISO 9001 does not replace the cavity flask.

Verify silicone certificates by matching lab, method, specimen, color, and pour to the cavity you will ship. A PDF titled FDA is not verification.

Uncured RTV kits and cured cavities use different clocks. Shelf life of a food-contact mold is heat, UV, oil, and jacket crease, not a ten-year carton

Store RTV cavities cool, dark, uncreased, and away from sulfur and tin tools. Keep the food-contact face clean. Never stack jackets into a fold.

RTV mold QC is master identity, pour and flash, key register, lot extraction, and a visual of the food face. A spatula report does not cover the cavity.

A gummy mold is a cavity a depositor fills, a gel sets in, and a dump station empties. Starch moguls, RTV trays, and rigid plastic are not the same tool.

Choose gummy molds from depositor pitch, dump method, and piece volume, not the cartoon. Starch, plastic, and platinum RTV trays are different line tools.

Production gummy trays are platinum RTV from a living mother, jacketed, and post-cured. 21 CFR 177.2600 extractives apply to the article, not a spatula.

Custom gummy cavities fail on starved ears, bad pitch, and dump tears, not on pretty CAD. Design volume, draft, and depositor register first.
