FloStor and NUMMI Revolutionize Automotive Material Handling

NUMMI’s transformation from a failing plant to a world-class automotive leader wasn’t luck—it was strategy, grit, and relentless improvement. With FloStor as their trusted integrator, custom-built automation systems fueled NUMMI’s rise, driving efficiency, safety, and quality to set a new global standard in manufacturing.

How NUMMI Turned Material Flow into a Competitive Advantage Through TPS-Aligned Automation

The Client: New United Motor Manufacturing Inc. (NUMMI)

NUMMI was a landmark Toyota-GM joint venture in Fremont, California, built to transform a previously underperforming automotive plant into a world-class production operation. Success required more than process discipline on the line. It demanded precise, reliable material handling across every assembly stage.

FloStor partnered with NUMMI to support this transformation by engineering integrated systems aligned with Toyota Production System (TPS) principles and continuous kaizen improvement.

FloStor and NUMMI integrated material flow

The Challenge

  • Legacy Operational Drag: The site inherited low morale and inconsistent quality outcomes from prior operations.
  • Complex Multi-Department Flow: Stamping, body, paint, and assembly required synchronized part movement with minimal delay.
  • Mixed-Model Production Pressure: Build-to-order sequencing increased material presentation complexity and timing sensitivity.
  • Cycle-Time and Throughput Constraints: Manual handling steps limited pace and introduced avoidable bottlenecks.
  • Safety and Ergonomic Risk: Repetitive handling of heavy components increased injury exposure and operator strain.

The Solution

FloStor delivered TPS-compatible, operator-assist automation focused on flow quality rather than automation for its own sake. Systems were designed to support people, stabilize process timing, and reduce non-value-added movement while preserving flexibility for model changes and field-tested refinements.

Design and implementation were collaborative from concept through launch, with iterative improvements built into deployment to satisfy kaizen-level performance expectations under real production conditions.

Systems Used

  • Delivery Flow Systems: Overhead tire line, seat component accumulation, rim delivery, and seat distribution infrastructure.
  • Automated Handling Solutions: Fuel tank loading and delivery, molding/cladding support, spare tire insertion, and sealant-related handling functions.
  • Presentation and Install Assist Platforms: Fuel tank, mounted tire, glass, HVAC, and instrument panel installation support systems.
  • Paced Work and Subassembly Support: Engine subassembly support, paced platforms, and configurable assembly aids.
  • Custom Fixtures and Mobility Assets: Application-specific racks, dollies, and ergonomic presentation devices.

The Power of Integration in Action

FloStor’s system-integration role connected engineering intent, line realities, and TPS process rules into one operational framework. Rather than introducing isolated equipment islands, each solution was tuned to upstream and downstream dependencies so parts arrived in the right sequence, orientation, and timing window.

This integrated approach reduced flow disruption during model launches and enabled rapid iteration when production feedback revealed improvement opportunities.

The Results

NUMMI established a more stable, responsive material handling environment that supported high-quality automotive production under demanding mixed-model conditions. Operator-assist automation improved handling consistency, reduced physical burden, and reinforced throughput continuity across critical stations.

The partnership also delivered long-term execution benefits through strong launch support, fast problem resolution, and persistent post-deployment optimization in line with kaizen expectations.

Key Performance Gains

  • Material Flow Stability: Better sequencing and presentation reduced line-side disruption
  • Model Launch Readiness: Fast-track deployment and on-floor tuning improved launch performance
  • Safety and Ergonomic Improvement: Operator-assist systems reduced heavy and repetitive manual handling exposure
  • Kaizen Execution Strength: Persistent refinement cycle improved real-world system performance over time

Why This Worked

This transformation worked because NUMMI and FloStor aligned technology decisions with production philosophy. TPS principles, human-centered automation, and iterative engineering were applied together as one operating model, not as separate initiatives.

  • TPS-Compatible Design: Systems supported flow, waste reduction, and quality discipline at station level.
  • Operator-Assist Strategy: Automation amplified human capability instead of replacing critical judgment.
  • Field-Tested Iteration: Design adjustments were made under real production conditions to reach target outcomes.
  • Integrated Engineering Partnership: Cross-functional collaboration from planning through launch sustained execution quality.
