Textures and Logos in Custom Silicone Tool Cavities
A logo easy to mill in aluminum can tear a 10A RTV skin. Set depth and draft on the master; laser-EDM in LSR steel is a different parts quote.

Balancing Pours in Multi-Cavity RTV Silicone Molds
If pocket 1 is full and pocket 8 is light, the pour and jacket are not balanced. RTV trays need even head and a flat mother mold, not an LSR cold-runner.

Keying Systems for Two-Part Silicone Mold Alignment
If two RTV halves can close 0.3 mm off and still look shut, they will. Key the jacket and use odd-count buttons; do not locate on the flash land.

Shrinkage Calculations for Precision RTV Mold Cavities
Paste 2% on a platinum RTV job and you cut the master wrong. Platinum holds ~0.1–0.3%; tin keeps moving. Coupon the dump, not an LSR steel factor.

Converting 2D Drawings and STEP into RTV Mold Geometry
A STEP of the product is not a production mother. Add split, jacket offset, and dump shrink, then name platinum or tin so RTV skins and LSR steel do not share one file.

Why Custom RTV Dump Prices Drop From 100 to 10,000
Dump price at 10,000 is not the 100-pour quote divided by 100. It drops where mix, setup, sag scrap, and mold amortization stop dominating each pour.

CNC vs 3D-Printed Masters for Low-Volume RTV Molds
For a custom RTV mold, the fork is CNC versus printed *masters*. Printed LSR cavities are a different, hot-tool exception. Finish and inhibition decide.

Low-MOQ Custom RTV Silicone Mold Partner Checklist
A low MOQ on a custom RTV mold is a setup-cost policy, not a kindness. Check master custody, kit size, recast, and whether the shop actually pours gloves.

RTV Vacuum Casting vs LSR Molding
RTV vacuum casting makes a pour cavity. LSR molding makes a vulcanized part. Soft tooling is an industry aside. Finished LSR parts are an HTV product or mold RFQ here, or a different LSR-tool RFQ - ask us.

Hidden Costs in Custom RTV Molds: Trim, Scrap, Recast
Mold price is the visible third. Split-trim labor, sag scrap, and recasts often outrun the first skin. Budget the leaks, not just the glove.
