Precision Labor.
Every Task. Every Volume.
DianCo Assembly executes the high-touch, detail-critical tasks that fall outside the reach of your automated equipment — the work that demands skilled human hands, rigorous process discipline, and a partner accountable for quality output, not just labor hours.
Manual Hand Assembly
& Sub-Assembly
When Your Line Needs Hands, Not Hardware
Injection molders, OEM assemblers, and contract manufacturers regularly encounter components that are impractical to automate — small runs, intricate geometries, orientation-sensitive parts, or assemblies that change too frequently to justify robotic tooling. DianCo Assembly fills that gap precisely.
Our workforce is trained to execute against your engineering drawings, physical samples, or documented work instructions. Every workstation follows a controlled process sheet. Every output is checked against a client-provided quality checklist before it leaves our hands.
We handle everything from simple two-part snap-fits to multi-stage sub-assemblies requiring sequential component insertion, torque-controlled fastening, and functional verification. Whether you need us to feed a downstream automated line or pack final assemblies for shipment, DianCo delivers a consistent, documented output.
Typical Clients: Injection molders managing short-run family tooling, OEMs with mixed-SKU assemblies, and manufacturers with seasonal complexity spikes.
Custom Kitting &
Subscription Bundling
Accurate at Volume. Flexible by Design.
Kitting and bundling are deceptively demanding. A missed component, an incorrect count, or a mismatched SKU that reaches the end customer creates returns, chargebacks, and brand damage that far exceed the cost of getting it right the first time. DianCo Assembly is built around getting it right the first time.
We assemble hardware packs, promotional bundles, subscription boxes, and multi-SKU retail kits to exact count-and-content specifications. Our process includes component verification at intake, assembly checklists at the station level, and final-count confirmation before sealing — ensuring that every kit that leaves our facility matches your bill of materials precisely.
For e-commerce brands and subscription businesses with high-volume monthly fulfillment cycles, we function as a seamless extension of your operations — absorbing the labor intensity of bundle assembly so your warehouse team can focus on throughput.
Typical Clients: E-commerce brands with subscription models, hardware manufacturers packing retail accessory kits, and promotional fulfillment operations.
Sorting, Rework &
Visual Quality Inspection
Turn a Quality Crisis Into a Resolved Shipment.
When a production batch fails incoming inspection — whether from excess flashing, cosmetic defects, labeling errors, or mixed lots — the operational pressure is immediate. You need a trusted partner who can mobilize quickly, work methodically, and deliver a clean, documented result. That is DianCo Assembly's rework capability.
We accept non-conforming product batches, execute 100% visual inspection against your defined acceptance criteria, and segregate conforming from non-conforming inventory with complete traceability. Our rework operators are trained to client-specific defect standards — not generic sorting — ensuring the decision-making at each station reflects your quality threshold, not ours.
For injection molders managing tool wear or process drift, we provide ongoing flashing remediation and light finishing that keeps your output shipping-ready without interrupting the molding cycle.
Typical Clients: Injection molders managing cosmetic defect waves, importers managing incoming quality from overseas suppliers, and manufacturers facing urgent rework-before-ship deadlines.
Contract Packaging
Shelf-Ready Product. Delivered on Schedule.
Final packaging is the last point of control before your product reaches a retail buyer, a distribution center, or an end consumer. It must be correct, consistent, and compliant with your retailer's or distributor's specification — every time. DianCo Assembly provides the manual packaging labor that meets that standard.
We handle the full range of retail and industrial packaging operations: poly-bagging and heat-seal finishing, hang-tag application to exact placement specifications, display tray and PDQ building, and master carton pack-and-seal. All operations are executed to a documented work instruction reviewed and approved by you before production begins.
For manufacturers managing new product launches, promotional seasonal variants, or retailer-specific compliance packaging, DianCo provides the flexible packaging labor capacity your in-house line cannot always absorb — without the overhead of permanent headcount.
Typical Clients: Consumer goods brands launching new retail SKUs, warehouse operations managing retailer compliance packaging, and manufacturers with seasonal display build programs.
