Built for OEM Production
We make products that fit where they’re meant to fit and do what they’re meant to do — so people stop thinking about them.
And that’s the point.
Built for Repeat OEM Production
Repeat OEM manufacturing depends on more than fabrication capability. It depends on manufacturing processes that remain consistent, predictable and repeatable long after the first component has been approved.
Stronghold combines practical engineering support with integrated manufacturing processes to help OEMs move confidently from prototype validation through to repeat OEM manufacture.
How we support OEM manufacturing
- OEM supply of custom sheet metal components
- Design and engineering support before production begins
- Manufacturing processes designed for high-repeat production
- Consistent quality and dimensional accuracy across production runs
- Reliable delivery aligned to ongoing manufacturing schedules
Design & Engineering Support
Can this component be manufactured consistently – not simply produced once?
That’s the question behind every successful repeat OEM production program.
Whether working from customer-supplied drawings or supporting product development, every project is reviewed for manufacturability before production begins, helping identify production constraints before they become production problems.

Typical applications
- Customer-supplied manufacturing drawings
- Prototype-to-production transition
- Existing products requiring manufacturing review
- Production transfer between suppliers
What this means in practice
- Review of manufacturability before production begins
- Assessment of tolerances, forming and assembly requirements
- Prototype validation before repeat manufacture
- Identification of opportunities to simplify manufacture
- Production-ready designs developed for consistent long-term manufacture
Punching (Turret punching)
Turret punching produces repeat features quickly and consistently, making it well suited to components manufactured in ongoing production where speed, repeatability and production efficiency are priorities.
Whether producing a prototype or an established production run, approved tooling and punching programs are standardised to maintain consistent feature quality and dimensional accuracy throughout repeat manufacture.
Manufacturability is reviewed before production begins to confirm feature geometry, tooling suitability and opportunities to integrate secondary operations, helping improve production efficiency across repeat manufacture.

Typical applications
- High-repeat production components
- Straight-line profiles, slots and repeat features
- Components incorporating louvres, embossing or formed details
- Repeat OEM production across low and high volumes
What this means in practice
- Fast, repeatable production at scale
- Consistent feature quality across production batches
- Efficient production of repeat components
- Integrated secondary operations including tapping, embossing and louvres
- Reduced handling between manufacturing operations
Cutting (Laser cutting)
Laser cutting produces clean, accurate profiles with tight control over geometry, supporting components that must fit consistently, assemble correctly and repeat reliably throughout ongoing production.
Supporting mild steel, stainless steel and aluminium, our laser cutting capability is suited to both prototype development and repeat OEM manufacture.
Every new component is reviewed for manufacturability before repeat production begins, helping identify production constraints early and supporting consistent outcomes across repeat manufacture

Typical applications
- Complex profiles and detailed geometry
- Tight tolerance components
- Prototype-to-production transition
- Ongoing repeat manufacture
What this means in practice
- Accurate cutting of complex shapes, curves, and detailed profiles
- Clean edges with minimal distortion
- Efficient material utilisation through optimised nesting
- Consistent repeatability across production batches
- Flexibility across a range of material types and thicknesses
Welding
Welding joins formed components into finished assemblies that must maintain structural integrity, dimensional accuracy and repeatable quality throughout ongoing production.
Whether manufacturing a prototype or an established production run, approved weld procedures and assembly methods are standardised to support consistent results from the first assembly through to the last.
Manufacturability is reviewed before production begins to assess weld access, assembly sequence and distortion risk, helping identify production constraints early and supporting repeat manufacture.

Typical applications
- Multi-component fabricated assemblies
- Structural components requiring reliable joint strength
- Products requiring dimensional accuracy after welding
- Repeat OEM production across low and high volumes
What this means in practice
- Consistent weld quality across repeat production
- Controlled distortion to maintain assembly accuracy
- Reliable alignment of fabricated components
- Reduced variation between production batches
- Assemblies prepared for downstream finishing and installation
Bending & Folding
Bending and folding transforms flat sheet into accurately formed components that must fit, align and assemble consistently throughout repeat production.
Whether producing a prototype or an ongoing production run, approved bend sequences are standardised to maintain dimensional consistency from the first component through to the last.
Manufacturability is reviewed before production begins to confirm bend geometry, flange dimensions and forming feasibility, helping identify manufacturing constraints before repeat production is released.

Typical applications
- Components requiring accurate fit and alignment
- Multi-bend parts with repeatable geometry
- Cosmetic panels where consistency is important
- Repeat OEM production across low and high volumes
What this means in practice
- Consistent bend angles and formed dimension
- Reliable fit between mating components
- Standardised bend sequences once approved
- Efficient production across repeat manufacturing runs
- Reduced variation between production batches
Powder Coating
Powder coating protects fabricated components with a durable, consistent finish that maintains appearance and performance throughout service while supporting repeat production.
Integrated finishing allows fabricated components to move efficiently from manufacture to coating, helping maintain production flow and consistent quality across ongoing OEM manufacture.
Finish requirements are reviewed before production begins to confirm coating suitability, surface preparation and application requirements, supporting consistent outcomes throughout repeat production.

What our clients say
We’re still using the Stronghold lockers we installed more than ten years ago.
We thought our design was all set, but Stronghold suggested some practical changes that made it better.
Stronghold have been building custom cabinets for us since 2001.
They supply components for us every month – on time & exactly to spec.
