Industrial prototyping service — ITM

Pilot2Plant (P2P) Injection-moulded plastic part prototypes with production logic.

Functional validation with industrialisable prototype moulds to make decisions before manufacturing the production mould.

  • Parts injected with real plastic material
  • Dimensional and functional validation
  • Risk reduction before the production mould

What is Pilot2Plant

Pilot2Plant (P2P) is ITM's prototyping service using industrialisable prototype moulds. Its goal is to obtain a minimum batch of injection-moulded plastic parts — with the final material — to validate design, process and tolerances before committing to the production mould.

The system is based on the combination of a standardised mould base with a machined insert tailored to the part geometry. The mould base acts as a reusable structural support; the insert reproduces the cavity geometry with the dimensional precision required for functional validation.

Unlike prototyping by 3D printing or direct machining, Pilot2Plant reproduces the actual injection process: material shrinkage, fill behaviour, ejection and dimensional stability. The result is parts that behave like production parts, not geometric mock-ups.

The service covers everything from the technical brief to delivery of the minimum batch with a results report, including DFM, insert design, machining, assembly and injection.

System components

  • Reusable mould base from our own inventory
  • Machined insert tailored to the part geometry
  • Feed system (runner, gate) adapted to the material
  • Ejection system integrated into the insert
  • Final plastic material per customer specification
  • Injection process equivalent to production

Available materials

Traditional prototype vs. Pilot2Plant

Not all prototypes provide the same level of validation. The Pilot2Plant approach goes beyond geometry and validates the actual behaviour of the injection process.

Prototype Mould to Production Mould — From Prototype to Production — Pilot2Plant ITM
Validation criterion Traditional prototype Pilot2Plant (P2P)
Geometry validation Yes, validates shape Yes, validates geometry + process
Material Simulated / substitute material Real plastic material (specified)
Process behaviour No process behaviour Real injection process
Material shrinkage Not reproduced Reproduced per material
Warpage and distortion Not evaluable Evaluable on injected part
Dimensional stability Limited / not representative Representative of production process
Transition to production mould Partial, with uncertainties Direct — transferable process data

The Pilot2Plant process in 5 steps

A structured workflow from the technical brief to delivery of the minimum batch with a results report.

  1. Technical brief

    Part definition, material, validation objective and required minimum batch volume.

  2. Mould base selection

    Selection of the standardised mould base compatible with the geometry, material and process conditions.

  3. Insert design

    DFM engineering applied to the insert: cavity design, feed system and ejection adapted to the process.

  4. Machining and assembly

    Manufacture of the insert to the required tolerances and integration into the standardised mould base.

  5. Injection and delivery

    Production of the minimum batch of parts injected with final material, results review and delivery with technical report.

Advantages of the Pilot2Plant approach

Pilot2Plant does not compete with 3D printing or machining. It is the only option when the goal is to validate a plastic part with the real material, the real process and industrial tolerances before manufacturing the production mould. It reduces the risk of costly corrections in advanced project stages.

The minimum batch obtained allows functional assembly tests, performance testing, customer approvals and CTQ criteria definition before committing the investment in the production mould.

  • Final plastic material — same behaviour as the production part
  • Full injection process validation: fill, shrinkage, ejection
  • Industrial tolerances achievable from the prototype stage
  • Direct transition to production mould — transferable process data
  • Reduced risk of costly modifications in advanced project stages

Technical capabilities of the service

Processable materials, achievable tolerance classes and surface finishes available in the Pilot2Plant service.

Materiales

  • Polyolefins: PP, PE-HD
  • Styrenics: ABS, PS, PC/ABS
  • Polycarbonate: PC, PMMA
  • Polyamides: PA6, PA66
  • Polyacetals: POM
  • GF-filled: PA6 GF30, PBT GF30
  • High performance: PPS GF40, PEEK GF30

Final material per customer specification. Option to use the same material grade as the production mould.

Tolerances

  • Normal class: ±0.08 – 0.10 mm
  • Reduced class: ±0.04 – 0.06 mm
  • Cavity tolerance: ±0.02 mm

Achievable tolerances depend on part geometry, material and nominal dimensions. Applicability should be confirmed based on the specific design.

Surface finishes

  • No requirement: Standard machined finish, non-decorative
  • VDI technical texture: Per VDI 3400 scale, reproducible in cavity
  • Industrial polish: Ra < 0.4 µm, suitable for functional parts
  • Mirror polish: Ra < 0.1 µm, for optical or high aesthetic demand parts

Surface finish is defined during the technical brief phase and applied to the machined insert before assembly.

Pilot2Plant service applications

Pilot2Plant is the right solution when geometric validation is not enough and the actual behaviour of the injected part is required.

Functional validation of parts and assemblies

Verification of fits, assembly interfaces, assembly tolerances and functional behaviour with the final material and process.

Testing with final plastic material

Mechanical, thermal or chemical compatibility testing with the exact material grade that will be used in production, not substitutes.

Geometry optimisation

Evaluation of geometry industrialisation — ribs, wall thicknesses, radii and gate locations — on real parts before defining the final mould.

Pre-production validation and industrialisation

Preparation of the technical file for the production mould: process parameters, CTQ criteria, dimensional reports and customer approvals.

Quality and validation

The Pilot2Plant service integrates ITM's quality management system, certified to ISO 9001. Each project includes a control plan with CTQ characteristic definition, selection of critical measurement points and inspection methodology.

Delivered parts are accompanied by a complete dimensional report, measured with calibrated internal metrology instrumentation.

Process traceability covers everything from the material grade to the injection parameters recorded during batch production, enabling reproducibility and direct transfer to the production mould.

Deliverable documentation

  • Dimensional report Measurement of critical points defined in the control plan. Nominal vs. actual comparison with deviations.
  • Roughness report Ra measurement on defined finish zones. Verifies compliance with the specified surface finish.
  • Process report Record of injection parameters: temperature, pressure, cycle time. Transferable to the production mould.
