The quotation states a unit price, a minimum quantity and sometimes a delivery term. It rarely states the calendar that starts when the mechanical design is released. That calendar – not the production line – is what determines when a new charger enclosure can ship.
This guide is part of our Charger Quality & Inspection. Read the full topic guide for the decisions that come before and after this step.
Why quotations show a price, not a calendar
Tooling time depends on the part: the number of cavities, the complexity of the mould, the surface finish, the number of trial loops and the queue at the tool shop. A quotation is issued before those variables are fixed, so the calendar is deliberately left open. The useful response is not a number from the factory but a staged plan from you: design release, steel order, trial dates, acceptance.
Stage-by-stage: design, steel, machining, trial
| Stage | Work | Dependency |
|---|---|---|
| Mould design | Layout, gating, cooling, ejection | Frozen mechanical design |
| Steel and standard parts | Material order, cavity and core blanks | Approved design, steel availability |
| Machining | CNC, EDM, polishing | Machining capacity |
| Trial loops | T1, T2, corrections | Mould assembly complete |
| Texturing and plates | Surface finish, print plates | Approved trial parts |
What runs in parallel with tooling
Certification preparation, artwork development, packaging structure, user manual and cable specification can all progress while the mould is being cut. The constraint is that artwork cannot be finalised before the enclosure dimensions are frozen, and certification needs a representative build. Running these in parallel is the single largest compression available, because it removes serial waiting rather than shortening a technical process.
T1, T2 and the correction loop in calendar terms
Each trial loop requires time to mould the parts, measure them, correct the tool and re-run. A simple enclosure may be accepted after one or two loops; a complex part with tight cosmetics may need more. The variation is why a tooling timeline should be expressed as a range with defined acceptance criteria rather than a single date. Budgeting for an extra loop is usually cheaper than compressing the final one.
Texturing, colour and print plates
Texture is applied after the tool is proven, and it can reveal cosmetic issues that were invisible on a polished surface. Colour matching, print plates for the enclosure and laser marking are separate items with their own queues. These are the stages most often omitted from a verbal timeline, and they sit on the critical path immediately before sampling.
Realistic total: new enclosure versus platform reuse
The comparison is not between fast and slow tooling but between tooling and no tooling. Re-badging an existing platform removes the mould design, steel, machining and trial loops entirely, leaving branding, packaging and documentation. A new enclosure adds all of those stages and therefore dominates the launch calendar. This is the practical reason a first branded order is often built on a platform.
Four honest ways to compress the schedule
- Use an existing platform and change only what does not affect the design
- Run certification preparation and artwork in parallel with tooling
- Freeze the mechanical design completely before releasing the tool
- Reserve tool-shop capacity in advance rather than entering the queue
What does not compress the schedule honestly: skipping a trial loop, approving from photographs, or releasing production before the golden sample is signed.
Schedule risks and buffers
The main risks are late design freeze, steel availability, a correction loop that exceeds the plan, texture approval, and certification findings that require an enclosure change. A project buffer of one to two weeks at the end of the tooling phase is normal practice. A plan without a buffer is a plan that assumes every loop passes first time.
Tooling timeline template
- Mechanical design release date
- Mould order and steel arrival date
- Machining completion date
- T1, T2, T3 planned dates with acceptance criteria
- Texture and print plate dates
- Engineering sample build date
- Golden sample and production release date
What a good tooling plan looks like at handover
At the end of the tooling phase, the programme should hold a small set of documents that make production repeatable: the accepted mould drawing, the trial report from the final loop, the agreed process window with material grade and shrinkage, the texture and colour references, the print plate approvals and the signed golden sample. Without them, production relies on the tool shop’s memory, and a future reorder may be built to a slightly different standard. The handover pack is also what supports a warranty discussion: if a later batch is challenged for appearance or fit, the accepted references are the measurement standard. A tooling plan that ends with a signed sample and no process window has left the most valuable part of the work undocumented.
FAQs
How long does a new charger enclosure mould take?
It depends on complexity, the number of cavities, the finish and the trial loops required. A plan built around defined milestones and an acceptance criterion is more reliable than a single number quoted before the design is frozen.
Can tooling and certification run at the same time?
Yes, once a representative worst-case build exists. Preparation, documentation and pre-scan can start earlier, and this parallel path is usually the largest schedule saving available.
What is the fastest route to a branded charger?
Re-badging an existing certified platform: logo, colour, labels and retail packaging on a design that is already tooled and tested. It removes the tooling calendar and most of the certification calendar at once.
