How Our Dual Business Model Works For You

As both an established industrial distributor and contract manufacturer, we avoid the supply chain challenges and markup pricing that affect traditional contract manufacturers. We purchase components at wholesale through our distribution relationships with over 100 manufacturers, then pass those savings directly to you.


This means the same machine assembly costs 20-30% less from us versus other contract manufacturers who must buy components through distributors at marked-up prices. We stock $3-4 million in inventory, providing buffer against supply chain disruptions without requiring you to carry component inventory.


Our engineering team evaluates your bill of materials for free, identifying drop-in equivalent components that reduce costs without compromising functionality. Customers typically save 15-30% off bottom-line costs by partnering with a company that handles both distribution and manufacturing.

Engineering Support and Value Engineering

Our engineering team brings over 200 years of combined experience with industrial automation products. We don't just build to your drawings, we actively identify opportunities to improve your designs for manufacturing efficiency and cost reduction.


  • Value Engineering Services

    We analyze your BOM to find high-quality, lower-cost alternatives. We leverage our relationships with component manufacturers to substitute parts that meet or exceed your specifications while reducing material costs. Many customers are surprised to discover significant savings without any performance compromise.


  • Design for Manufacturability

    Design for manufacturability reviews catch potential production issues before they impact schedule or cost. Our engineers understand how parts fit together in production and can recommend minor design changes that substantially reduce assembly time or improve reliability.

  • Technical Consulting

    Technical consulting helps you specify components correctly from the start. Our engineers know which components work reliably in different applications and which ones create problems. This knowledge prevents specification errors that lead to costly redesigns.

Production Capabilities

We handle projects from single prototypes through volume production with appropriate processes for each stage.

  • Prototype Builds

    Receive focused engineering attention to validate designs and identify manufacturing issues. We document assembly processes and component fit issues, creating the foundation for efficient volume production. Our engineers work closely with yours during prototype builds to refine designs before committing to production tooling.

  • Low to Medium Volume Production

    Low to medium volume production benefits from flexible manufacturing systems that accommodate product variations without dedicated production lines. We handle batch sizes from 10 units to several thousand annually, adjusting our processes based on your production requirements and delivery schedules.

  • Volume Production

    Volume production implements process optimization, supply chain management, and quality systems appropriate for higher volumes. We establish component inventory management, develop detailed work instructions, and implement quality control procedures that ensure consistent results across production runs.

Quality and Testing

Less than 0.5% of our assemblies are returned due to workmanship issues. This performance results from systematic quality management rather than inspection alone.


  • Incoming Inspection

    PB+ verifies component quality before parts enter production. We catch supplier defects early, preventing assembly of nonconforming materials.


  • In-process Verification

    In-process verification monitors critical characteristics during assembly rather than waiting for final inspection. Our technicians check key measurements and assembly parameters at defined stages, enabling immediate correction when needed.

  • Functional Testing

    Functional testing validates equipment performance before shipment. We develop test procedures based on your specifications, documenting performance data that proves equipment meets acceptance criteria. Test equipment includes electrical testing to 600 amps, leak decay testing, burn-in testing, and custom test fixtures for application-specific validation.

 Certifications and Standards

Our facility maintains certifications that support quality manufacturing:


ISO 9001:2015 certified by TRNA


UL 508A certified for industrial control panel fabrication

EPTAC IPC certified for electronic assembly and soldering


ESD-safe workstations for handling sensitive electronic components


These certifications demonstrate systematic quality management and technical competence in critical manufacturing disciplines.

Who We Build For

We work with established companies like Amazon, Thermo Fisher, and General Dynamics, as well as startups launching their first products. Project scope doesn't determine service quality; every customer receives thorough consultation and engineering support.


Startup companies benefit from our ability to handle the complete manufacturing process, enabling them to focus on product development and sales rather than building manufacturing infrastructure. We've helped companies launch products that wouldn't have been commercially viable without our value engineering and volume purchasing power.



Established manufacturers use our services to handle overflow production, manufacture specialized products outside their core capabilities, or reduce total cost of ownership by outsourcing assembly operations.


Getting Started

We begin with a consultation to understand your machine specifications, production volumes, and delivery requirements. Our engineering team reviews your drawings and BOM, identifying potential issues and cost reduction opportunities.


After value engineering your design, we provide a detailed quote covering component costs, assembly labor, testing requirements, and delivery schedule. Once you approve the quote, we source components, develop assembly procedures, and build your first units with appropriate engineering oversight. We document the process and refine procedures based on what we learn during initial production.

FAQs

  • What is a turnkey machine solution?

    A turnkey machine solution is an assembly that can function as a complete product as opposed to a subassembly. This often includes electro-mechanical assembly, software programming, component procurement, testing, packaging, and delivery. You receive a fully functional, tested system ready for delivery. 


  • What types of turnkey machines do you build?

    We design and build custom assemblies for Warehouse Automation & Robotics, Life Science, Biotechnology, and Medical Devices, Industrial Machinery, Building Automation, Aerospace and Defense, Semiconductor Equipment, Pharmaceutical, Food and Beverage, and Chemical, Water and Wastewater treatment. We have built complete machines like blood processing machines, bioreactors, glue fillers, strain testers, mobile robot test stations, hydraulic test stands, and more.

  • How long does it take to design and build a custom turnkey machine?

    Project timelines vary significantly based on complexity and the long-lead item required for your build. Simple automation equipment may require 4-6 weeks, while complex integrated systems can take 6-12 months. Our engineering team provides detailed project schedules during the proposal phase, breaking down design, procurement, fabrication, and testing timeframes.
