From “standard” enclosures to customized solutions: how the market is changing (and why it benefits you)

A few years ago, most of our sales were based on “standard” enclosures with no modifications. Today, reality looks very different: more than 65% of our sales now include some level of customization (machining, printing, adhesive front panels/membrane keyboards, or a combination of all of them). And the trend keeps growing.

To put it into perspective: around 75% of our sales used to be standard enclosures. Today, customization has become the norm.

Quick fact: if your electronics require connectors, buttons, LEDs, displays, antennas or visible branding… you almost certainly need a customized enclosure.

What has changed? The demand for “complete solutions”

The reason is clear: customers no longer want “just a box”. They want a complete solution that helps them:

  • Reduce costs (fewer intermediaries, fewer errors, less rework).

  • Shorten lead times (everything handled by one supplier).

  • Avoid technical issues (connector alignment, tolerances, sealing, etc.).

  • Protect and enhance brand image (high-quality UV printing, durable and legible markings).

In practice, almost all standard enclosures require some kind of adaptation to fit the electronics and the final product design.

The old paradigm: buy here, customize there

For years, the typical process was:

  1. Buy the enclosure from a manufacturer or distributor.

  2. Send it to a third party for machining.

  3. Look for another supplier for printing.

  4. Cross your fingers and hope everything fits and arrives on time.

This model creates friction: higher costs, more coordination and more risk.

The new paradigm: “the ideal enclosure, already customized”

At SUPERTRONIC, with more than 50 years of experience, we help our customers find the ideal enclosure:

We deliver the standard enclosure already customized and ready to assemble your electronics.

With clear advantages:

  • Highly competitive price-quality ratio.

  • No minimum order quantity.

  • Very short lead times.

  • Technical support to avoid surprises during production.

The key differentiator behind our growth in customization

Six years ago, we identified something very revealing: many customers were extremely satisfied with our customization services (machining, printing, adhesive front panels/membrane keyboards…), but sometimes they already had enclosures from other manufacturers or could not find the exact reference in our catalogue.

Instead of losing those projects, we expanded our offering:

Today, we customize not only our own enclosures, but also enclosures from any other manufacturer.

This allows our customers to:

  • Keep the same enclosure and avoid redesigning their electronics.

  • Speed up delivery of customized enclosures.

  • Reduce customization costs.

Which types of customization are growing the most?

For most customers, the winning combination is:

1) CNC Machining

We machine all types of openings: connectors, cable glands, displays, grills, recesses, and more.

2) UV Printing

We print any image, text or logo with photographic quality directly onto the enclosure surface.

Why this shift also drives revenue growth

When customization is handled by a single supplier:

  • Projects move faster.

  • Errors and returns are reduced.

  • Customers repeat because the workflow is simple.

Result: we have significantly increased our turnover and consolidated our market position thanks to a clear value proposition: complete solutions with consistent quality, competitive pricing and fast delivery.
