Your Assembly and Kitting Concerns Addressed


Wisconsin Stamping & Manufacturing – Your idea. Our ingenuity. A perfect match.

Our integrated manufacturing approach eliminates subcontracting of components and streamlines the supply chain resulting in efficiency gains and elimination of unnecessary markups. Combined with automated assembly processes and volume purchasing power through our WorldSource Fastener division, we typically achieve meaningful cost reductions versus traditional multi-vendor approaches.

Every assembly program includes a comprehensive Production Part Approval Process (PPAP) (when required) with documented control plans, measurement system analysis, and capability studies. We significantly reduce defect rates through in-process inspection, automated inspection systems, poke-yoke initiatives, and final quality audits. Our ISO 9001:2015 certification ensures consistent quality system application.

With 170,000 square feet of production space,  and capacity for 250,000 cubic feet of staged assembly and kitting inventory, we accommodate demand spikes without extending lead times.  Vendor-managed inventory programs eliminate lead time concerns entirely.

Our engineering team provides complimentary Design for Assembly (DFA) analysis, identifying opportunities to reduce components, simplify assembly, and maximize manufacturability of components, in order to cut costs. Using GD&T analysis and tolerance stack-up calculations, we typically identify cost reduction opportunities while improving quality.

While mega-manufacturers focus on million-unit programs, we excel at 100 to 100,000 unit runs with the flexibility smaller assemblers lack. Our sweet spot ranges from simple to complex assemblies and kits requiring precision metal fabrication combined with value-added assembly and fasteners – capabilities most competitors must outsource.

We maintain full compliance with ISO 9001:2015 standards. Documentation packages can include Certificates of Conformance, PPAP submissions (Levels 1-5), IMDS reporting, material certifications, and custom requirements as required by your industry. Our quality team has decades of experience with inspection and compliance requirements across a wide variety of industries..

Comprehensive NDAs protect your designs and processes. Our ISO-certified document control system ensures revision management and restricted access. We’ve maintained confidentiality for  all customers over 65 years without a single breach. You can be assured your intellectual property will remain completely safe and secure.
