Process

Clarify the project early, reduce trial-and-error later.

We divide manufacturing projects into confirmable stages: define files and goals first, close structure, tooling and production risks, then move toward stable delivery.

Define files and goals first,
close key risks,
then move toward stable delivery.

Engineering Flow

Break project progress into engineering nodes that can be judged and traced.Clear engineering nodes,
traceable risks.

The point of the process is not to list steps, but to make each step answer three questions: are inputs complete, are risks closed, and can outputs support the next stage?

Each step confirms inputs, risks and outputs.

Input

Confirm the project boundary first

Drawings, samples, quantity, requirements, use environment, appearance target and cost target are collected first.

OutputRequirement listRisk issue list

Review

Judge whether it can be manufactured steadily

Review wall thickness, demolding, shrinkage, strength, assembly and tooling implementation.

OutputStructure suggestionsProcess boundary

Verify

Reduce uncertainty early

Use 3D printing, mold flow analysis, structural simulation or local structure adjustment to verify key risks.

OutputValidation conclusionOptimization plan

Mold

Move into tooling plan and trial mold

Confirm parting, gate, venting, cooling and ejection plan, then record mold correction points after trial.

OutputMold planTrial record

Delivery

Deliver by dimension, appearance and assembly

During pilot or production, track dimensional consistency, appearance stability and delivery rhythm.

OutputQualified samplesBatch delivery

Risk LoopIf a risk is not closed, return to structure, process or tooling plan for optimization.

Flow Charts

Use flow charts to show inputs, judgment, correction and delivery.

Process management reduces repeated communication: collect files first, judge engineering issues, return to the related step when risks are not closed, and enter tooling and injection delivery after confirmation.

**Process review**Put drawings, samples, target cost and use environment on the same table to avoid repeated missing information.

**Stage progress**Requirement, structure, prototype, mold, injection and delivery need clear inputs and outputs.

**Risk loop**If a structure, mold or validation problem is not closed, return to the related step before moving forward.

Risk loop: do not enter the next stage until issues are closed.
