Custom silicone development · RTV mold MOQ from 20 · DFM & prototype support
Explore practical silicone mold guides from RUUIPON, covering design, release, materials and production planning. Start with the problem you need to solve, then open the relevant product page when you are ready to discuss a quotation. CAD, drawings, samples and measured reference photos can all help define the project.
A broad DFM guide covering release, undercuts, splits, detail, multi-cavity layout, material selection and prototype validation.
The information that helps a supplier identify the correct mold structure, process, quantity and documentation requirements.
Understand when a flexible casting mold, compression tool or LSR tool fits the product.
Understand what food-contact documentation means and what to request for the destination market.
Use this cluster for one-piece vs two-part molds, undercuts and split molds, registration keys, wall thickness and support, edge radius, logo/text detail, tolerance and shrinkage, and DFM review.

Title preview
High-tear RTV is a poured mold. High-tear LSR is a heat-cured part. Stay on platinum RTV until volume, flash, or a named part compound outgrow the block.

A clear platinum RTV mold copies the master into resin. Glass-like LSR lenses are a different quote. Control dust, bubbles, polish, and inhibition.

Anti-static RTV is dissipative, not EMI-conductive. Use it so a food, potting, or device tray doesn't hold dust. Spec a resistivity band, not a filler

FSR (FVMQ) resists many fuels that swell ordinary RTV. It is a part compound, not a poured mold. Name the fluid and swell test before you change chemistry.

Self-lubricating LSR blooms a designed fluid after cure. In a poured mold that oil fouls chocolate and resin. Use release and geometry, not shop oil in

UV-cure silicone can freeze a thin mold skin in seconds. Depth, shadows, and inhibition decide if it beats platinum RTV. Thick blocks still need a pour.
Read article -RAL and Pantone are targets, not RTV SKUs. Match with platinum-safe silicone pastes, a stated Delta E, and the real thickness, or the cavity will drift.
