The Challenge

A validated prototype needed to transition into small-batch production.

The product was functional — but not production-optimized.

Challenges included:

  • Inconsistent assembly time
  • Overcomplicated part geometry
  • Material waste
  • Unclear QC criteria
  • No structured production workflow

The goal was to develop a controlled, repeatable small-batch production system.

Scope of Work

  • Design refinement for small-batch production
  • Tolerance and assembly simplification
  • Fixture and jig development
  • Workflow sequencing
  • Batch planning
  • Quality control framework
  • Documentation

Phase 1 — Production Review

Before producing anything:

The prototype was audited for:

  • Part count reduction
  • Fastener simplification
  • Tolerance stack-up risks
  • Material waste optimization
  • Fabrication time

Several components were redesigned to reduce complexity without compromising performance.

Phase 2 — Workflow Structuring

Instead of producing randomly, a structured workflow was defined.

Production was divided into stages:

  1. Component fabrication
  2. Sub-assembly
  3. Final assembly
  4. Inspection
  5. Packaging

Each step had:

  • Defined inputs
  • Defined outputs
  • Clear inspection checkpoints

Small jigs and fixtures were introduced to ensure repeatability.

Phase 3 — Batch Fabrication

Small-batch production began.

Focus areas:

  • Material efficiency
  • Process consistency
  • Assembly timing
  • Dimensional repeatability

Digital fabrication tools (CNC, 3D printing, laser cutting) were used strategically depending on:

  • Volume
  • Material
  • Precision requirement

Production was monitored and documented.

Phase 4 — Quality Control

Instead of “visual inspection only,” measurable criteria were introduced:

  • Dimensional tolerance checks
  • Surface finish consistency
  • Assembly fit validation
  • Functional test checklist

A simple QC sheet ensured repeatability between units.

This transformed fabrication into controlled production.

Final Output

  • Optimized production-ready design
  • Defined batch workflow
  • Repeatable assembly structure
  • QC framework
  • Clear scaling pathway
