Custom Enclosure Manufacturing Services – Plastic & Metal Enclosures
Bespoke Plastic and Metal Enclosures for Electronic Products
Nitronics provides a complete custom enclosure design and manufacturing service for electronic, electrical and industrial products.
From early-stage prototypes and design development through to production-ready plastic and metal enclosures, we help customers turn their ideas into professionally manufactured components and complete assemblies.
Our in-house capabilities include design support, CNC milling and 3D printing, allowing our team to assist with prototypes, modifications and product development. For specialist manufacturing processes such as injection moulding, sheet metal fabrication and powder coating, we work with an established network of trusted manufacturing partners.
This gives our customers access to a wide range of manufacturing technologies through one experienced UK supply partner.
Whether you need a single prototype enclosure, low-volume production or a scalable solution for higher-volume manufacture, Nitronics can help manage the process from concept through to finished product.
Complete Custom Enclosure Solutions
Every project is different. Material, production volume, environmental requirements, appearance, tooling cost and unit price can all influence the most appropriate manufacturing process.

- Filter Moulding
- Overmoulding
- Insert Moulding
- 3D Printing
- Design & Tooling
- CNC Milling
- Sheet Metal Fabrication
- Laser Cutting
- Metal Bending & Forming
- Welding
- Powder Coating

Plastic Injection Moulding
For medium and higher-volume production, plastic injection moulding provides an effective way to manufacture repeatable, professional-quality enclosure components.
Nitronics can support customers throughout the process, including design development, material selection, tooling and production.
Through our trusted manufacturing partners, we can source injection-moulded parts for a wide range of electronic and industrial applications.
We can also help customers consider manufacturability at the design stage, reducing the risk of unnecessary tooling modifications once a product moves into production.
Filter Moulding
Where applications require specialist filtered plastic components, Nitronics can work with customers to develop and source suitable filter moulding solutions.
Our approach allows the moulded components to form part of a wider manufacturing project, rather than requiring customers to manage multiple individual suppliers.
Overmoulding
Overmoulding can be used to combine different materials within a component or add features such as additional protection, grip, sealing or strain relief.
This can be particularly useful for electronic products, cable assemblies, connectors and products designed for demanding operating environments.
Nitronics can support the design, tooling and manufacture of custom overmoulded components through our specialist manufacturing network.
Insert Moulding
Insert moulding allows components such as threaded inserts, contacts and other metal parts to be incorporated directly into a moulded plastic component.
This can improve product durability, simplify final assembly and provide a more professional production solution.
We can work with customers from the initial design stage to determine the appropriate insert and moulding process for their application.
In-House 3D Printing
Our in-house 3D printing capability is particularly valuable during product development.
Rather than committing immediately to production tooling, customers can produce physical prototypes to check:
- Component fit
- PCB positioning
- Connector locations
- Cable routing
- Mounting points
- Overall dimensions
- Assembly requirements
- General product appearance
Design changes can then be made before committing to production manufacture.
This can significantly reduce development risk, particularly for new electronic products where the PCB, wiring, connectors and enclosure all need to work together.
In-House CNC Milling
Nitronics also offers in-house CNC milling, providing additional flexibility for prototypes, modifications and custom components.
CNC machining can be particularly useful where low quantities are required or where an existing enclosure needs to be modified with openings, mounting features or other product-specific details.
Combined with our engineering and manufacturing capabilities, this allows us to support both prototype development and ongoing production requirements.
Design and Tooling Support
A successful enclosure starts with a good design.
Our team can work alongside customers to help develop enclosure concepts into practical, manufacturable products.
Because Nitronics also specialises in electronics manufacturing, we can consider more than just the enclosure itself.
We can help consider how the PCB, wiring looms, cable assemblies, switches, displays, connectors, batteries and other components will fit and operate inside the finished product.
Once the design is ready for manufacture, we can coordinate the appropriate tooling and production process through our trusted specialist partners.
Custom Sheet Metal Fabrication
For industrial electronics, control equipment and products requiring additional strength, a custom sheet metal enclosure can be an excellent solution.
Nitronics can provide sheet metal fabrication through our specialist manufacturing partners, supporting everything from prototypes and small production batches through to repeat manufacturing.
Capabilities include:
- Laser cutting
- Precision bending and forming
- Welding
- Fabrication
- Cut-outs and apertures
- Mounting features
- Inserts and fixings
- Powder coating
- Custom finishes
Enclosures can be manufactured to suit the specific dimensions and requirements of your product rather than forcing your electronics into a standard off-the-shelf enclosure.
Laser Cutting, Bending and Welding
Modern laser cutting and precision bending allow complex sheet metal components and enclosures to be manufactured accurately and consistently.
Where required, fabricated components can also be welded to create strong, permanent assemblies.
Nitronics can manage these processes as part of the overall project, helping reduce the number of suppliers our customers need to coordinate.
Powder Coating & Finishing
Custom metal enclosures can be supplied with powder-coated finishes in a range of colours and specifications.
Powder coating provides both an attractive professional finish and additional protection for the metal enclosure.
We can also coordinate labelling, identification and other finishing requirements as part of a complete product manufacturing package.
From Enclosure to Complete Electronic Product
One of the biggest advantages of working with Nitronics is that the enclosure does not have to be treated as an isolated component.
We can combine enclosure manufacturing with our wider electronics manufacturing capabilities to provide a complete end-to-end manufacturing solution.
Nitronics can support:
Custom Enclosure → PCB Assembly → Wiring Looms & Cable Assemblies → Programming → Testing → Final Assembly → Complete Box Build
This means your custom plastic or metal enclosure can arrive at Nitronics ready for our production team to install the electronics, wiring, connectors, displays, switches, batteries and other components.
The completed product can then be programmed, functionally tested, labelled and prepared for delivery.
Prototype to Production
Developing a new electronic product often requires several manufacturing processes.
Nitronics can help simplify this journey.
1. Design
We work with your existing design or help develop the enclosure around your electronics and product requirements.
2. Prototype
Using technologies such as 3D printing and CNC machining, prototypes can be produced before committing to production tooling.
3. Review
The enclosure can be checked against the PCB, wiring, connectors and other components, allowing any required changes to be identified.
4. Tooling & Production
Once approved, we can coordinate the appropriate production process, including injection moulding or sheet metal fabrication.
5. Electronic Assembly
Nitronics can manufacture and install the PCB assemblies, wiring looms, cable assemblies and other electronic components.
6. Testing & Final Assembly
The finished product can be programmed, tested, labelled and supplied as a complete manufactured assembly.
