Engineered to specification, not to catalogue..

A catalogue product is the right answer when your requirement matches a standard configuration. Custom engineering is the right answer when it doesn't — and that happens more often than catalogues admit.

We work on custom engineering programmes when:

• The required test combines multiple standards in a single chamber (IPX9K rain plus MIL-STD-810 dust plus thermal cycling, for example)
• Chamber dimensions or sample geometry fall outside catalogue ranges
• A test method needs adaptation to a specific product class
• An existing test setup needs re-engineering for new compliance requirements
• The product itself is the deliverable — a mechatronic system, automation rig or instrumented assembly that does not exist on the market

Our work spans test systems, mechatronic products and the components that fall between them.

We start every custom programme the same way: by understanding the problem before quoting a solution.

Requirement intake. We sit down with the customer's engineering team — usually a video call, sometimes on site — and work through the actual problem. What is the product? What test must it survive? What standard governs it? What is the operational environment? What constraints does the project have on schedule, footprint, power, controls, integration?

Concept design. Based on the agreed requirement, we produce a concept design that captures the proposed approach — system architecture, key mechanical elements, instrumentation, control philosophy. This is the document the customer reviews and approves before any detailed engineering begins.

Detailed engineering. Mechanical, electrical and control engineering proceed in parallel. Standard parts are sourced; custom mechanical components are designed and machined; control systems are programmed against the agreed specification.

Manufacturing and integration. The system is built in our Ankara facility. We integrate the mechanical structure, fluid systems, instrumentation, control hardware and software in-house — not as a chain of outsourced sub-suppliers.

Factory acceptance test (FAT). Before shipping, the system is brought to operational state and verified against the agreed acceptance criteria. The customer is invited to witness FAT — either on site or remotely.

Site acceptance test (SAT) and commissioning. After delivery, we commission the system at the customer's facility. Calibration, integration with the customer's existing systems and operator training take place at SAT.

Even when a project is custom, the compliance framework is usually not. Custom test systems still need to apply the right method per the standard — pressure tolerances per IEC 60529, spray geometry per MIL-STD-810 Method 506, vibration profile per RTCA DO-160 Section 8.

A significant part of our custom engineering work is engineering compliance into the system itself: nozzle geometry that meets ISO 20653 §5.2, chamber surface finishes that don't disturb salt-fog test conditions, control software that records traceable test data per the procedure's evidence requirements.

This is where standard-specific knowledge matters — and where catalogue-led test equipment vendors often fall short.

Automation, PLC/HMI programming and control software are core engineering capabilities at ULMEKA. We deploy them in our test systems and custom mechatronic builds — programming PLC and HMI systems that control test sequences, integrating sensors and actuators, building safety interlocks, designing operator interfaces.

While test systems and mechatronics are our primary focus, we also selectively take on standalone machine automation projects that align with our engineering capabilities.

Some practical examples of work we have done — described in general terms because each customer's specifics belong to them, not on a public page:

• A combined rain and high-pressure water jetting chamber that integrates MIL-STD-810 Method 506 and ISO 20653 IPX9K in a single test platform
• A walk-in chamber for testing large-format defense subsystems with combined IPX and dust ingress evaluation
• A specialised vibration fixture for a product where the catalogue accessories did not match the sample geometry
• An instrumented test rig for a product family whose qualification standard required real-time monitoring of multiple parameters during exposure

These projects share a common pattern: a real engineering problem, an agreed scope, an iterative design phase, and a system that does what it was built to do at FAT.
