Services / Prototyping & manufacturing

Prototype to manufacturing, fewer surprises.

Ideambox helps plan prototypes, validate the right risks, prepare DFM, review BOM and tooling decisions, and guide supplier conversations in Taiwan and China.

Functional hardware prototype installed for validation

Prototype methods chosen by risk, not by habit

SLA for ergonomic look-and-feel, SLS for snap-fit testing, CNC aluminium for thermal validation, soft-tool silicone for short-run sealing, MJF nylon for living hinges, FDM only for the cheapest gross-volume mockups. Each prototype is born to answer one specific question we list on the test plan — IEC 60068 cycle, drop test, IP-X4 spray, or first-touch ergonomic review.

EVT, DVT, PVT — gated, not blurred

EVT proves the architecture works. DVT proves the design is manufacturable and certifiable. PVT proves the supplier can build it repeatedly at AQL 1.5 / 2.5 / 4.0. Each gate has written exit criteria — measurable, not opinion-based — so you don't end up paying for steel tooling on a design that hasn't passed EVT.

Tooling brief, not just a CAD file

Family mold vs single cavity vs multi-cavity decision based on annual volume. Steel grade (P20 prototype, 718H production, S136 medical). Cavity count math against cycle time and CapEx amortisation. Gate type (sub-gate, hot tip, hot manifold). Texture spec (Mold-Tech MT-11010, VDI 3400 Ch33). The molder gets a brief, not surprises.

Supplier brief that lands honest quotes

RFQ package with drawings, STEP, BOM with manufacturer part numbers, AQL inspection criteria, target tooling vs unit cost split, payment terms (30/40/30), and lead time expectation. Three suppliers quote in 5–10 days on identical scope — not a one-month back-and-forth of "what do you mean by X?".

Prototype strategy

Six prototype types. Don't build the wrong one.

Each prototype answers a different question and costs a different amount. Founders waste months and €30–80k building appearance models when they need architecture rigs, or building functional EVTs when they still need to prove the basic mechanism. The plan saves the money.

Appearance model

Painted SLA, no electronics. €800–2k. For investor demo, brand review, or trade-show booth. Cannot validate fit, mechanism, or sealing.

Architecture rig

CNC + 3D-print enclosure with eval-board electronics inside. €3–8k. Validates PCB outline, antenna keepout, battery volume, assembly sequence. Built before custom PCB layout.

EVT functional

Custom PCB + SLS/MJF enclosure. 3–5 units, €5–15k. Validates electronics architecture, firmware, sensor placement, antenna gain. Drives the freeze for DVT.

DVT pre-tooling

Soft-tool or CNC parts at production materials. 20–50 units, €15–40k. Validates DFM, certifications (EMC, IP, drop), supplier capability. Last stop before steel.

EVT golden samples

First-shot parts from production tooling. 50–100 units. Calibrates the AQL inspection plan, MTM firmware test, and operator training before pilot run.

Pilot production

100–500 units at production tooling, production assembly line. Validates yield, ramp curve, packaging, logistics, and the field-failure rate that justifies your warranty reserve.

Taiwan and China supplier guidance

Do not let the supplier define your product by accident.

Supplier feedback is valuable, but only when the product team knows what must be protected: performance, quality, cost target, assembly, testing, serviceability, and long-term reliability.

  • BOM and cost feedback
  • Factory audit and supplier capability checks
  • Tooling and pilot-production decisions
  • Assembly and quality review

Supplier selection

Supplier choice is an engineering decision.

The cheapest quote can become the most expensive path if the supplier cannot control tolerances, finishes, electronics assembly, testing, documentation, or project communication.

  • Process capability and past product fit
  • Tooling and sample quality
  • Electronics assembly and testing capability
  • Material and compliance documentation
  • Communication and engineering feedback quality
  • Risk before deposit or tooling commitment

Supplier red flags we surface

  • 10% under all other quotes — usually a misread scope or a margin trap that becomes a change order at month 3.
  • No ISO 9001 or weak QC team — outgoing AQL is a hope, not a process.
  • Pushes back on UL/IEC component spec — they want to swap to unbranded, which kills your CE/FCC technical file.
  • No engineering response in 48h — communication won't get better after PO.
  • No tooling DFM feedback — they'll quote what you sent and surprise you at first-shots.
  • 50% deposit upfront with no milestone — your leverage disappears the day you wire.
