Assembly Services – Complete Product Assembly & Integration

At DSI Manufacturing, our work doesn’t end when your parts leave the laser cutter or CNC machine. We offer full assembly services so your project can go from individual components to a finished, ready-to-ship product — all under one roof.

Whether you need a simple sub-assembly or a complex multi-component build, DSI’s team delivers precision, consistency, and speed. With over 40 years of experience in precision sheet metal fabrication, CNC machining, powder coating, and complete product assembly, we provide a true one-stop manufacturing solution.

Why Assembly Matters in Manufacturing

Outsourcing your assembly process to a trusted partner like DSI offers several advantages:

Fewer vendors to manage – We fabricate, machine, finish, and assemble in-house.
Shorter lead times – No delays from shipping parts between different suppliers.
Better quality control – All processes are handled by our ISO 9001:2015-certified team.
Reduced total costs – Eliminates multiple handling and freight steps.
Stronger supply chain security – Reliable, domestic production in Rogers, Minnesota.

Our goal is to ensure your finished product is production-ready, tested, and packaged to your specifications — so it reaches your customers without additional handling.

Types of Assembly We Offer

1. Mechanical Assembly

Our mechanical assembly capabilities range from basic fastening to complex mechanical integration. We handle everything from rivets and screws to threaded inserts, hinges, handles, and casters.

2. Sub-Assembly & Modular Components

If your product ships in modules or sub-sections, we can pre-assemble these to streamline your production line or end-user installation.

3. Electromechanical Assembly

Working with both fabricated housings and machined parts, we integrate electrical components such as wiring harnesses, LED lighting, switches, and power supplies into your assembly.

4. Custom Fixture & Display Assembly

We frequently assemble retail fixtures and displays, combining our powder coating finishes, custom metal fabrication, and precision hardware installation to create professional, ready-to-install units.

Our Assembly Capabilities

Because we control the full manufacturing process, DSI can ensure tight integration between fabrication, finishing, and assembly. Our in-house capabilities include:

Precision Fitting & Alignment – Ensuring components fit exactly as designed.
Fastening & Hardware Installation – Rivets, PEM hardware, threaded inserts, hinges, and more.
Welding & Finishing – MIG, TIG, and laser welding for seamless integration.
Electrical Integration – Light wiring, switches, connectors, and component mounting.
Packaging & Kitting – Assembling multiple items into kits for distribution.
Quality Testing – Verifying assemblies meet dimensional and functional specs.

If a part needs additional finishing — such as anodizing, plating, or silk-screening — we work with trusted partners to deliver a complete, finished product.

Integrated Manufacturing — All Under One Roof

One of DSI’s biggest strengths is our ability to combine assembly with our other core services:

Precision Sheet Metal Fabrication – State-of-the-art laser cutting, forming, and welding for accurate, repeatable parts.
CNC Machining – Multi-axis machining for complex, tight-tolerance components.
Powder Coating – Durable, attractive finishes in a wide range of colors.
Prototyping – Rapid iteration and small-batch builds to refine designs before full production.

By combining these capabilities, DSI can fabricate, finish, and assemble your project without unnecessary hand-offs — cutting lead times, reducing costs, and ensuring perfect compatibility between parts.

Industries We Serve

Our assembly services support a wide variety of sectors, including:

Retail – Store fixtures, point-of-purchase displays, shelving, and signage.
Medical – Equipment housings, instrument panels, and ergonomic stands.
Electronics – Enclosures, chassis, and integrated electrical assemblies.
Automotive & Transportation – Brackets, frames, and modular system components.
Construction & Industrial – Guarding systems, control boxes, and safety enclosures.

Because every industry has unique requirements, we tailor our assembly processes to meet your specifications, industry standards, and regulatory needs.

Quality Assurance

Our ISO 9001:2015 certification means your assemblies go through rigorous inspection at every stage. From checking raw materials to verifying final fit and finish, our quality process ensures:

Dimensional accuracy
Proper hardware installation
Structural integrity
Functional testing where required
Cosmetic and finish consistency

We document inspection results so you have full traceability for your records.
