How does Nordmould approach a project from prototype to production?
Disclaimer. Nordmould is a new brand. The scenarios below are illustrative worked examples created to demonstrate how we think about part design, tooling selection, and service-tier logic. They are not descriptions of past client engagements, and no real company names, products, or testimonials have been used. The engineering reasoning is genuine; the projects are hypothetical.
What can Nordmould actually do for a typical product company?
These four scenarios walk through the questions a product or engineering team would ask at each stage of a project — from design review through to first-off inspection. Each one is labelled with the service tier, material, and cost and lead-time logic that would apply in a real engagement.
Illustrative example: bringing a sensor enclosure from prototype to 5,000-unit production
Part type: Two-part snap-fit enclosure for an indoor environmental sensor. Outer dimensions roughly 90 × 60 × 25 mm, wall thickness 1.8 mm, integrated snap hooks, IP rating required.
Engineering challenge: The original CAD had 0° draft on four internal ribs and a wall thickness that varied between 1.2 mm and 3.1 mm in different zones. The variation would have caused visible sink marks on the cosmetic face and inconsistent snap-hook deflection force.
DFM decisions Nordmould would recommend: Uniform 1.8 mm wall throughout the rib network; 1.5° draft on all vertical faces; snap-hook geometry adjusted to give a consistent 0.4 mm deflection range; gate moved from the centre of the cosmetic face to the parting line to eliminate a gate witness mark.
Tier chosen: Bridge. A 5,000-unit target with a realistic chance of a repeat order at 10,000 units fits aluminium tooling well. The up-front cost stays lower than a hardened-steel tool while still delivering parts with a matt surface finish and tight dimensional repeatability.
Material: ABS — good stiffness-to-weight ratio, straightforward to colour-match, and compatible with the ultrasonic-welded joint that seals the two halves.
Lead-time and cost logic: Aluminium tooling typically takes 4–6 weeks from approved design to first shots. At 5,000 units, the tooling cost amortised per part is modest. The written Nordmould quote shows tooling cost separately so the customer can see the break-even unit volume clearly.
Illustrative example: short-run industrial connector housing for a machinery OEM
Part type: Single-body connector housing, 40 × 30 × 18 mm, UL94 flame-retardancy required, dimensional tolerance critical on the terminal-pin bore pattern.
Engineering challenge: The customer needed 300 parts for a field trial before committing to a full production run. Hardened-steel tooling for a 300-piece trial would have been difficult to justify on cost alone.
DFM decisions Nordmould would recommend: Simplify the locking lug geometry to eliminate a side action, reducing tooling complexity and cost without affecting function. State the bore-pattern tolerance explicitly in the DFM note so the partner factory machines the tool to that datum.
Tier chosen: Rapid for the trial phase (soft tooling or 3D-printed bridge parts to validate fit and function), then Bridge once the design is locked. The customer gets injection-moulded parts that match production intent without committing to expensive hardened steel until volumes justify it.
Material: PC — capable of achieving UL94 V-0 at relevant wall thicknesses (the specific rating is confirmed for the selected grade at DFM stage, as flame-retardancy ratings are wall-thickness-dependent). PC is dimensionally stable and suitable for the pin-bore tolerances required.
Lead-time and cost logic: Rapid-tier parts can typically be produced in days to one or two weeks rather than the full tooling cycle, giving the OEM field-trial parts quickly. The transition from Rapid to Bridge is a single formal quote step with Nordmould; no repeat DFM review is needed if the design has not changed.
Illustrative example: consumer-goods lid with high-gloss cosmetic finish
Part type: Cosmetic lid for a kitchen appliance, 120 × 80 mm, high-gloss surface required on the outer face, living hinge connecting lid to body.
Engineering challenge: High-gloss surfaces expose every flow line, knit line, and gate witness mark. The living hinge requires precise wall thickness — typically 0.2–0.5 mm at the hinge line — with the gate positioned so polymer fills both wings of the hinge simultaneously and molecular orientation runs across the hinge. Material selection is critical: only materials with high molecular chain flexibility survive repeated flexing at hinge thickness.
DFM decisions Nordmould would recommend: Gate at the centreline of the hinge so both halves fill from the same front. For the high-gloss cosmetic face, polish the cavity to the required SPI finish before trial shots. Add a shallow texture break at the parting line perimeter to manage flash visibility on the non-cosmetic underside.
Tier chosen: Production. A consumer appliance with an expected multi-year production life and annual volumes in the tens of thousands is a natural Production-tier job. Hardened steel tooling amortises quickly at those volumes and withstands the shot count.
Material: PP (polypropylene) for the living hinge component. PP is the standard material for injection-moulded living hinges — it develops the molecular orientation required for flex life during moulding, and the gate position is critical to achieving this. If the cosmetic outer surface requires ABS or PMMA colour and gloss characteristics on a separate part of the assembly, those components can be moulded as separate parts and assembled; PMMA and other rigid amorphous materials are too brittle for living-hinge features.
Lead-time and cost logic: Production-tier hardened-steel tooling takes longer to cut than aluminium — typically 8–11 weeks for a part of this complexity. The per-part price at volume is lower, and tool life is measured in hundreds of thousands of shots.
Illustrative example: flexible over-moulded grip for a handheld device
Part type: Two-shot or insert-moulded grip sleeve for a handheld diagnostic tool; rigid PP substrate with soft-touch TPE over-moulded on the gripping surfaces.
Engineering challenge: TPE adhesion to PP substrate depends on the surface energy of the substrate and the gate layout for the second shot. Poor adhesion leads to peel failure in field use.
DFM decisions Nordmould would recommend: Specify a mechanical interlock geometry — small undercuts in the PP substrate that the TPE keys into — alongside chemical adhesion. Gate the second shot at the base of the grip section so TPE flows up and fully encapsulates each interlock feature.
Tier chosen: Bridge for development validation; Production if the device reaches commercial volumes. Over-moulding tooling is inherently more complex, so understanding the shot sequence and adhesion mechanism in Bridge tier before committing to hardened steel reduces risk.
Material: PP substrate, TPU or TPE over-moulding layer. TPU provides better abrasion resistance for a high-use handheld product; TPE is easier to process if shot count is modest. Both bond mechanically and chemically to PP with appropriate gate design.
Lead-time and cost logic: Insert-moulded or over-moulded parts require two tool sets or a two-shot tool, which increases tooling cost. Nordmould quotes both components together and will flag if a simpler assembly approach (press-fit grip sleeve rather than over-moulding) would achieve equivalent performance at lower tooling cost.
Frequently asked questions
Are the projects on this page real past client work? No. Nordmould is a new brand. Every example on this page is an illustrative scenario, purpose-built to show how we approach part design, tooling choices, and tier selection — not a record of past client engagements.
Which service tier is right for a first production run of a few thousand units? The Bridge tier is usually the right starting point. Nordmould uses aluminium tooling to hold down up-front cost while still producing parts with production-grade surface finish and dimensional consistency for runs of a few hundred to several thousand units.
Can Nordmould handle parts that need to meet EU regulatory requirements? Production-tier orders include a formal process-validation step and full dimensional inspection documentation. Where specific certifications are needed — for example medical or food-contact compliance — Nordmould will confirm availability and scope at quote stage.
What does a free DFM review actually cover? Nordmould reviews your STEP or PDF file for wall-thickness uniformity, draft angles, sink-risk zones, undercut count, and gate placement options. You receive a short written note — typically within two working days — with any recommended changes before tooling is ordered.
How does Nordmould price a project? Pricing has two components: tooling (from €3,000, one-off) and piece-part price (unit cost multiplied by order quantity). Nordmould provides both numbers in the written quote so you can model total cost of ownership across multiple runs.
