Tooling and mold development

Yes. Projects can start from 2D drawings, 3D / CAD files, physical samples or product concepts; the available information is reviewed before tooling.

No. Drawings, samples or dimensioned references can be enough for the first review; CAD data helps with precise mold structure development.

Product geometry, dimensions and tolerances, wall thickness, parting and draft considerations, material and hardness, and logo or surface details.

Yes. Hardness, color and surface finish are confirmed on samples before production approval.

Yes. Required adjustments are confirmed based on sample feedback before the next tooling or sampling step.

Yes. Overmolding tooling includes insert positioning, shut-off design and retention features reviewed at the mold structure stage.

The approved sample and confirmed specifications become the reference for production and repeat OEM/ODM orders.

No. Silicone is flexible, but elasticity has limits, and forced demolding is where parts tear, deform or pick up flash. Undercuts, sharp internal features and sealed hollows still need a deliberate demolding strategy: draft on load-bearing walls, parting lines placed away from critical surfaces, and — where the geometry demands it — cores, sliders or manual de-molding steps that add cost and cycle time. The right question is not whether silicone can survive ejection, but how many forced releases per cycle your quality standard can tolerate over the tool’s life. Share the CAD or 2D with critical dimensions marked, and we will review the undercut features in DFM and confirm the mould route — and any manual steps — before tooling starts.

Cavity count trades a larger tooling investment against a lower unit price, so the answer starts with forecast volume and reorder frequency, not with the quote. Fewer cavities mean lower tooling cost and faster first samples — sensible for new products whose demand is unproven. More cavities reduce unit cost and raise capacity, which pays back once volumes are stable, but also increases tool size, press requirements and the cost of any future modification. Phased approaches are common: start with a lower cavity count, then add cavities in a follow-up tool phase once the product is confirmed. Share your forecast volumes, launch dates and reorder pattern with the CAD, and we will propose a cavity configuration with the tooling-versus-unit-cost trade-off made explicit.

Treat mould terms as part of the commercial agreement, not an afterthought. The points to put in writing: expected mould life against your projected volumes, who owns and stores the tool, what routine maintenance is included and how often, how repairs are charged, and which wearing parts — ejector pins, seals, inserts — are kept on hand to avoid downtime on repeat orders. Ownership and transfer conditions matter especially if you expect to move production later. These terms are confirmed in the tooling agreement before mould production starts. For the wider ownership, storage and transfer picture, see our guide on custom silicone mold ownership. Share your volume forecast and reorder plans, and we will return the tooling terms with the quote.
