Manufacturing Engineering Co-op — Martinrea International
Merged two spot-welding sub-cells into one by redesigning tooling and integrating pneumatic actuation to eliminate duplicate processing.
Consolidated 2 welding cells to 1
~2× throughput improvement (cycle time reduction)
~$100K/year labour savings
$8K tooling cost reduction
Eliminated redundant part handling steps
Two identical parts processed in separate weld cells
Mirror parts required separate setups and changeovers
Cycle time bottleneck limited plant optimization
Needed reuse of existing tooling + minimal downtime
Redesigned tooling for dual-orientation part compatibility
Added secondary lower electrode without weld interference
Introduced pneumatic actuation for tooling repositioning
Converted full copper plate to localized copper inserts in aluminum base
Maintained compatibility with existing weld infrastructure
Production-focused mechanical design under strict cost, downtime, and manufacturability constraints. Delivered measurable throughput and cost improvements through tooling and process consolidation.
