DFM for data centres: enabling faster, cooler, more reliable scaling

Data centres are undergoing a massive overhaul to keep up with the demands of AI. Because AI requires much more computing power than traditional tasks, it generates more heat, wears out hardware faster and needs to remain online 100% of the time.

While trying to keep up with these technology demands, companies are also encountering real-world roadblocks: there is not enough electricity available, environmental regulations are becoming stricter and building new facilities is becoming more difficult. This means that every new data centre must be built faster, operate more efficiently and use designs that can be easily replicated and repeated.

That's why Design for Manufacturability (DFM) is increasingly becoming a competitive advantage for data centre equipment manufacturers. A well-managed DFM process reduces costly redesigns, improves yield and aligns part performance (thermal, structural, EMI) with what high-volume production can reliably deliver.

Dynacast—through its engineering-led die casting approach—positions DFM as more than a checklist: it is an early-stage collaboration that connects part design, tooling strategy, alloy choice and process simulation to produce parts that are stronger, lighter and easier to manufacture.

Dynacast's DFM philosophy: refine early, produce better

Dynacast's DFM guidance underscores a simple reality: small geometry decisions can have a significant impact on quality, tool life, cycle time and cost. In Dynacast's DFM FAQ, Senior Application Engineer Max Gondek emphasises the value of early collaboration, noting how minor adjustments, such as improving wall thickness uniformity, draft angles and feature placement, can enhance metal flow, reduce cycle times and avoid expensive secondary machining.

Early collaboration with the Dynacast team is a critical part of an effective DFM process. By engaging Dynacast's application engineers early in the design phase, potential manufacturability challenges can be identified and resolved before tooling is committed. This proactive partnership helps teams make informed design decisions upfront, reducing risk, minimising rework and ensuring a smoother transition from design to production.

This DFM approach is not about redesigning products from scratch. Instead, it focuses on refining existing designs so they can be manufactured consistently, efficiently and at scale.

What Dynacast evaluates during DFM (and why it matters for data centres)

Dynacast's design advice highlights a simple truth: even tiny changes to how a part is shaped can make a huge difference in how well it performs, how long the equipment lasts, how quickly it can be made and how much it costs.

The following Dynacast DFM principles reflect the manufacturing requirements of high-performance data centre components:

• Maintain uniform wall thickness This helps the metal cool uniformly, prevents defects and speeds up production.
• Use appropriate draft angles Adding a slight taper allows parts to be ejected smoothly from the die without damaging the tooling.
• Round corners and edges Adding small radii helps the metal flow better and makes the final part and the die much more durable.
• Build strength with ribs, not bulk Using ribs or webs adds the necessary stiffness without making the part too heavy or prone to air pockets.
• Test with simulations first Running digital tests identifies issues such as poor flow early, which is essential when the final part must be perfect.

How die casting DFM improves data centre components

Dynacast supports high-volume production, enables thin-walled precision and integrates features directly into castings to reduce assembly steps and cost. Aluminium, zinc and magnesium alloys further support the strength, thermal performance and dimensional accuracy required by hyperscale and enterprise data centres.

When combined with DFM, die casting helps manufacturers optimise for outcomes that directly impact scale, performance and reliability, including:

• Part consolidation: Fewer parts and fasteners through integrated features
• Improved thermal performance: Better heat flow in heat sinks, cold plates, manifolds and enclosures
• High-volume consistency: Reliable fit and dimensional control across large production runs
• Lower total cost: Higher yield, faster cycle times and fewer secondary operations
• Faster scale-up: Faster production ramp-up during platform refreshes and periods of market expansion

As a result, Dynacast positions its role in modern data centres as enabling consistent quality and rapid deployment across a wide range of applications, including server and AI hardware, cooling systems, liquid cooling components, PSU housings, fibre optic connectors and mounting hardware.

Connecting DFM benefits to data centre market pressures

DFM is valuable in any industry, but it becomes especially strategic in the data centre market, where capacity is projected to nearly double by 2030, power availability and speed-to-power decisions increasingly shape deployments, and hyperscalers continue to invest aggressively in new builds. In this environment, manufacturing efficiency, predictability and thermal performance are no longer incremental advantages—they are critical enablers of scale.

As hyperscale expansion accelerates and AI drives new thermal and structural demands, manufacturers need partners who can translate performance requirements into repeatable production. Dynacast positions DFM as a strategic, simulation-informed collaboration, helping teams refine designs early, protect tooling, improve yield and scale high-precision die cast components for modern data centres.
