Stage

Engineering / quotation

Figures on this page are CAD only. We are not claiming poured production pads. Customer PDFs named three families at about 75 x 75, 50 x 50 and 35 x 40, with silicone wall 2 mm or 2.5 mm. The shop built STP solids so pull, blends, draft and outside support could be argued in 3D. Jacket vs floppy skin was still open. Shore A was not locked.

CAD from the pad-mold review. Not a completed-production result.

Second size in the same family — wall and radius should not drift.

CAD used to compare cavity count, wall thickness and silicone usage.

0.5 mm wall is not a rounding error

Across a large architectural skin, 2 mm vs 2.5 mm changes silicone volume, tear, flex, handling weight and sag when filled. Convert PDF to STP before you buy silicone kilograms. If the sheet will be heavy, plan a rigid jacket in the same review — not after the first pour pancakes.

What to send

  1. PDF or STEP for every pad size that must share handling rules
  2. Chosen wall (2 vs 2.5 mm here), pull direction, jacket yes/no
  3. Cavity count per size if you already have a plant preference

FAQ

Did these molds ship?

Not evidenced here. Engineering/quotation. CAD only.

Can we mix 2 mm and 2.5 mm in one family?

You can, but operators will feel it. This review wanted one rule.

RTV stay on WYD?

Yes. Send the pad family to /contact/.

Send the three sizes as one family

If wall is still '2 or 2.5 mm', pick it before we calculate silicone. CAD review is cheaper than a floppy pour.
