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.

Glass needs a real silane primer and a thermal plan. Room-temp platinum RTV on glass is a prototype bond. Hot LSR overmold is a different quote and crack

A human can peel an RTV undercut that a robot cannot. On custom molds, design peel, keyed splits, or cores. Robotic LSR ejection is a different quote.

0.05 mm on micro LSR is a capability claim, not a default. An RTV mold copies the master; platinum shrink is about 0.1–0.3%. Don't promise that band from

Rotary 2-shot LSR over PC/ABS is a parts cell. On this site the analog is platinum RTV poured over a rigid master or frame at room temperature, not a hot

0.2 mm is a local LSR fill limit, not an RTV cavity spec. On a poured mold, 0.2 mm is usually flash or a detail coat — not a part-wide wall you dump into.

Flex PCBs survive silicone only if polyimide, solder, and chips take the process. Prefer room-temp platinum RTV when LIM heat would crack the stack.
Read article -HCR clamp is area times cavity pressure times a margin. RTV analog is box straps and a rigid jacket so the split seats — not thermoplastic tons or LSR

VDI 3400 is an EDM roughness scale. MT 11000 is a Mold-Tech catalog grain. On RTV, the grain lives on the master — not on a 20A jacket you cannot spark.

Core shift is steel moving in LSR. The RTV analog is a wandering mandrel and a sagging jacket. Support the core, key the OD, and map wall thickness.

Silicone hinges flex by elastomer strain, not PP orientation. Size t and R from peak strain, then cycle-test the grade. An RTV mockup is not the life
