Custom OEM Electronics

From your idea to a production-ready electronic subsystem.

Not every application fits into a predefined product family. When your equipment requires a unique electronic solution — a specialized control board, a power management module, a sensor interface, or a complete embedded system — KELD develops it from the ground up, with full ownership from concept through serial production.

HOW CUSTOM DEVELOPMENT WORKS AT KELD

We begin with your requirements, your constraints, and your timeline. Our engineering team works alongside yours to define the optimal architecture, select components, and design for manufacturability from the earliest stages.

The result is not just a prototype that works. It is a production-ready product, industrialized with quality planning, tested with full traceability, and manufactured with the same discipline we apply to every solution in our portfolio.

WHY OEMS CHOOSE CUSTOM OVER STANDARD

  • Cost optimization: a custom design includes only the features your product actually needs, eliminating the cost overhead of general-purpose controllers.
  • IP protection: your product’s control logic and functionality remain proprietary — not shared with competitors who buy the same off-the-shelf unit.
  • Differentiation: custom electronics enable features, performance levels, and user experiences that standard solutions cannot match — giving your product managers a genuine competitive edge in the market.
  • Lifecycle control: with a dedicated design, you control the evolution roadmap — updates, cost reductions, and compliance adaptations happen on your schedule, not your supplier’s.
  • Time-to-market: with a co-engineering partner who also manufactures, you eliminate the handoff delays and coordination risk of working with separate design firms and contract manufacturers.

FOR PRODUCT MANAGERS: ELECTRONICS AS A COMPETITIVE WEAPON

If you are responsible for your product’s roadmap, custom electronics give you capabilities that catalog components never will: proprietary control algorithms that deliver better efficiency than your competitors, connectivity features that enable new service models, user interfaces that differentiate your equipment at the point of sale, and the ability to respond to market opportunities with firmware updates rather than hardware redesigns.

KELD’s co-engineering model means your product team has a direct line to electronics expertise. When you identify a market opportunity, we evaluate feasibility, prototype quickly, and industrialize with discipline — turning your product vision into a production-ready reality.

OUR COMMITMENT

Every custom project is backed by KELD’s full value chain: co-engineering and DFM, quality planning (APQP), flexible manufacturing, full unit traceability, and lifecycle management including component obsolescence and regulatory updates.
