The Challenge

18-Week Lead Times Delaying Machine Deliveries

The client builds custom food processing lines — filling, packaging, and conveyance systems — for Fortune 500 food and beverage manufacturers. Every machine requires NEMA 4X stainless steel washdown panels that meet FDA 21 CFR Part 110 and USDA hygienic design standards.

Their in-house panel shop was struggling with two compounding problems: sourcing 316L stainless steel enclosures with acceptable lead times, and maintaining the specialized HACCP documentation required by their end customers. Average panel lead time had stretched to 18 weeks — the longest item on every machine build schedule.

The client needed a panel partner with established stainless steel enclosure supply chains, HACCP documentation expertise, and the capacity to scale with their growing order book.

The Solution

NEMA 4X Washdown Panel Program With HACCP Documentation

Outsourced Controls established preferred vendor relationships with Rittal and Hoffman for 316L stainless enclosures, reducing enclosure lead time from 12 weeks to 3 weeks. Combined with our dedicated production cell and HACCP documentation package, total panel lead time dropped from 18 weeks to 8 weeks.

  • 316L stainless steel enclosures with continuous weld seams and sloped tops — hygienic design standard
  • HACCP documentation package: BOM traceability, material certifications, and signed FAT reports
  • Allen-Bradley CompactLogix and PowerFlex VFDs — client's standard platform
  • IP66/NEMA 4X rated throughout — suitable for high-pressure washdown environments
