Quick answer: The Protective Case Customization Process runs through six gates: inquiry and requirement lock, drawing review, tooling, trials and first article, production with liner fitting, and inspection before shipment. A typical project takes 55 to 70 days, including 18 to 25 days of tooling and two trial rounds spanning ten days. Each gate ends with a signed output, not a promise.

1. The Six Gates and the Total Clock

The Protective Case Customization Process has six gates, one signatory each: sales signs the requirement, the structural engineer the drawing, the tooling supervisor the trial report, quality the first article, the plant manager release.

4 TrialsTool, resin, colour chipThree first articles7–10Quality
5 ProductionFirst article, kitted partsFinished cases12–15Planner
6 InspectionCases, packing listRelease note1–2Quality lead

Gate time totals 42 to 59 days; quotes land at 55 to 70, the gap being steel, trial cooling and queues. Ordering steel on day two overlaps tooling and saves three days, the only slack in the Protective Case Customization Process.

2. Inquiry and Requirement Lock

Inquiry, the first gate of the Protective Case Customization Process, turns a request into quotable terms. Four variables move price: new tool or modified insert, egg-crate foam or cut EVA, volume tier, and standard or custom colour. A new tool costs 18,000 to 35,000 yuan, an insert 3,000 to 6,000, an EVA die 800 to 1,500, and custom colour starts at 200 pieces. The requirement sheet fixes dimensions, liner, colour with a Delta E ceiling, volume split and terms; the sales lead signs.

3. Drawing and Structural Review

Review takes three to five days, the cheapest gate in the Protective Case Customization Process. The engineer checks draft, wall uniformity, rib thickness, hinge boss, rim width and stacking path.

ItemRuleCost of ignoring it
Draft angleAt least 1 degreeScuffing, whitening, sticking
Main wall2.5 to 4 mmSink marks and warp
Rib thickness0.6 of main wallSink on the opposite face
Rim width12 mm or moreGasket clashes with latch
Hinge boss5 mm or moreScrews strip with use

Output is a tool change list: which rib thins, which radius opens, whether the rim gains two millimetres. The engineer signs before steel is ordered.

4. Tooling, Trials and First Article

Tooling takes 18 to 25 days in the Protective Case Customization Process; modifying a tool 5 to 8. Two trial rounds sit three days apart: fill and distortion first, dimensions second. Three first articles are sealed, measured and dropped.

Trial checkLimitAction if out
Outer sizePlus or minus 2 mmRework cavity
Part weightWithin 3 percentCheck melt and shot
Rim flatness0.5 mm or lessRework rim insert
ColourDelta E 1.5 or lessRecheck resin batch
Latch cycle200 cyclesRework latch pocket

Release needs every dimension in tolerance and colour within Delta E 1.5. The tooling supervisor and quality signs, and the master sample is kept 12 months for later runs of the Protective Case Customization Process.

5. Mass Production, Liner Fitting and Shipping Release

Production runs 12 to 15 days per 500-piece batch; a projected area above 0.12 square metres needs 800 tonnes. Each shift starts with the master sample, resin drying and mould temperature.

The liner runs in parallel: egg-crate foam in three days, EVA with a two-day die and three days of cutting. Bonding rests four hours before closing, a common rush point in the Protective Case Customization Process. Inspection is booked 48 hours ahead at AQL 2.5.

Conclusion

Six gates work because each hands over a document: requirement sheet, tool change list, three first articles, patrol sheet, release note. Add ten days of buffer to 42 to 59 days and overlap tooling by three, and a 55 to 70 day promise holds. That is how the Protective Case Customization Process stays predictable.
