Why Your Next HMI Project Needs an Engineering Partner, Not Just a Parts Supplier
Let’s be honest. When you’re up against a tight deadline for a new product launch, the last thing you want is a generic “supplier.” You need an Engineering Partner. They must understand your design struggles, anticipate manufacturing headaches, and, frankly, make your life easier.
Here at RH Technical Industries, we understand that the world of interfaces (HMIs) has changed dramatically and continues to do so. That old, reliable membrane keypad you ordered five years ago? It probably won’t cut it for your sleek, next-generation product design. This is especially true if that design is destined for a harsh industrial setting or a demanding medical environment.
This shift in complexity is why we’ve focused relentlessly on one thing. That is, evolving our already deep partnership to provide even more robust Engineering Solutions.
Your Project’s Biggest Risk?
It’s Not the Component Itself.
As engineers, we know that when you hand over a finished design for production, the project’s risk spikes. We help answer the critical questions: Will your customers find this interface intuitive? Will that embossed button hold up to continuous use? Will the shielding be adequate to protect against electromagnetic interference?
That’s where we step in. Our top strength isn’t just the manufacture of reliable, beautifully finished parts. We are, however, very proud of that—but our engineering team is what sets us apart.
We don’t just wait for your final spec sheet. RH wants to collaborate with your design team from the outset. Why? Because working together early helps us, help you:
- Mitigate Manufacturing Errors: We can flag potential production issues before they become costly tooling mistakes, saving you time and money.
- Boost Functionality and Aesthetics: We help push the boundaries, integrating features like capacitive switching or ‘Dead-Front’ graphics (Secret Til-Lit Panels) to create a premium, intuitive product your customers will genuinely love.
- Ensure Fit for Purpose: Whether your HMI needs to be sealed against dust or survive extreme vibration, we guarantee the solution is built for its real-world environment.
Choose a Reliable Engineering Partner for End-to-End Control
When you work with RH, you’re tapping into a comprehensive, end-to-end manufacturing process—all right here in the UK.
Why does that matter to you? Control means speed and quality.
From the moment we receive your brief, we control the entire chain. Our dedicated Screen and Digital Print Department ensures perfect colour matching and graphic durability. Our CNC Machining and Tooling capabilities ensure precision, and our Assembly and Finishing teams manage complex integration like backlighting and final testing.
This level of control eliminates the uncertainty and delays often associated with fragmented supply chains. Uncertainty and delays are a major challenge. The result is a seamless, quality-assured HMI solution delivered right out of the box.
What Modern Interfaces Demand
If your newer designs are moving away from older solutions, we’ve got you covered. Our expanded capabilities focus on modern requirements:
- Advanced Keypads and Capacitive Switches: Providing highly responsive, intuitive user experiences that elevate your brand.
- Dynamic Graphics and Illumination: Using technologies like Light Guide Film and Secret Til-Lit Panels to declutter the interface and provide essential information only when needed.
- Extreme Durability: Our Graphic Overlays and Custom Labels are engineered for high heat, corrosion, and high impact. Need proof? Look to professional cricket. Our labels regularly withstand the impact of a cricket ball travelling at over 100 mph, but still need to look perfect for all the TV cameras.

Let’s Talk Early
Don’t wait until the design is locked down. This is especially important if you have a new project brewing or are struggling to find a durable, aesthetically pleasing interface for your next product. Reach out to our engineering team for an initial design review. Stop wrestling with spec sheets and start collaborating on a superior product. If you’re ready to see the process in action, please feel free to arrange a company visit.
Let’s build something better, together.
