STILL HAVE A QUESTION?
What We Do
At Encuro, we design and manufacture custom electronics enclosures around your PCB, sensors, connectors, batteries, displays and internal components.
From first prototypes to field-test units and small-batch runs, we help you turn your electronics layout into a professional enclosure that fits properly, functions reliably and represents your brand.
Built for Prototype Electronics
Off-the-shelf project boxes rarely match your PCB, connector layout or product identity. Encuro gives you a faster route to custom prototype enclosures without early tooling costs, long development delays or generic-looking housings.
We support IoT startups, electronics engineers, product teams and integrators who need custom enclosures for testing, demos, field trials and early-stage product validation.

Protection & Gaskets
1. PETG-CF (Carbon Fiber Reinforced Polyethylene Terephthalate Glycol)
Overview: Our flagship material for demanding structural applications. By infusing premium PETG with chopped carbon fibers, we drastically increase rigidity and dimensional stability while retaining excellent chemical resistance.
Key Properties:
- High tensile strength and extreme rigidity (low flex).
- Excellent impact resistance compared to standard carbon-fiber filaments.
- Low shrinkage and warping for high-precision mechanical fits.
- Good chemical resistance to acids, alkalis, and hydrocarbons.
Target Use Cases: Rugged field-trial enclosures, structural internal chassis, industrial monitoring casings, and high-wear operational environments.
2. ASA-CF (Carbon Fiber Reinforced Acrylonitrile Styrene Acrylate)
Overview: The ultimate material for high-stress outdoor deployment. This engineering-grade polymer combines the exceptional UV and weather resistance of ASA with the lightweight rigidity of carbon fiber reinforcement, preventing warping under extreme solar exposure and mechanical loads.
Key Properties:
- Exceptional UV, weather, and environmental aging resistance.
- High structural stiffness and dimensional stability over long-term outdoor exposure.
- Increased thermal resistance compared to standard filaments.
- Premium, low-gloss matte black technical finish that hides layer lines perfectly.
Target Use Cases: Outdoor sensor enclosures, marine electronics housings, automotive exterior components, and infrastructure monitoring equipment exposed to harsh sunlight and weather.
3. TPU-95A HF (High-Flow Thermoplastic Polyurethane)
Overview: An industrial-grade elastomer engineered for high-speed, reliable production of flexible parts. With a Shore hardness of 95A, it provides rubber-like elasticity combined with high tear resistance, making it essential for environmental sealing.
Key Properties:
- High flexibility, elasticity, and excellent impact damping.
- Outstanding wear, abrasion, and tear resistance.
- Excellent resistance to oils, greases, and many common chemicals.
- High-flow properties ensuring clean, precise geometry for tight seals.
Target Use Cases: Custom weatherproof gaskets, sealing rings, impact-resistant protective boots, vibration-damping mounts, and flexible cable strain reliefs.
4. ABS (Acrylonitrile Butadiene Styrene)
Overview: A classic, industry-standard engineering plastic known for its impact toughness and thermal performance. It allows for mechanical post-processing like heat-set inserts or solvent welding.
Key Properties:
- High impact resistance and toughness.
- Good heat resistance (up to approx. 100°C).
- Excellent machinability (drilling, tapping, and post-processing).
Target Use Cases: Functional mechanical prototypes, indoor industrial equipment, and heat-exposed internal brackets.
Engineering Note: Encuro specialises in optimising print orientation and wall thicknesses to maximize the isotropic strength of these materials based on your specific PCB layout, thermal dissipation needs, and environmental exposure. For custom material requirements (e.g., ESD-safe or flame-retardant blends), please consult directly with our technical team.
Frequently Asked Questions (FAQs)
Q1. Whats the turnaround time? Typical turnaround for prototypes is 2–4 working days, depending on complexity and finishing requirements. Batch orders generally take 2–6 weeks, influenced by order size, material choice, and whether tooling or post-processing (like painting or coatings) is required. We’ll provide an estimated lead time upfront, and for urgent projects, we can offer expedited services where possible.
Q2. What industries do you serve? We specialise in enclosures for IoT, electronics, and technology startups, MedTech/ health, consumer gadgets, wearables & fitness tech, cleantech/ energy, robotics/ automation, agritech, smart homes and construction tech.
Q3. What file formats do you accept? We typically work with STEP and STL files, as these are the most reliable for 3D printing and CAD adjustments. If you only have a sketch, drawing, or another format (e.g. IGES, OBJ), send it over — we can usually convert or recreate it into a printable file.
Q4. Do you offer design tweaks? Yes — we can make light CAD adjustments to ensure your enclosure prints correctly and fits your components. This might include things like adjusting wall thickness, resizing standoffs, or refining cut-outs. For bigger changes (e.g. a full redesign), we’ll let you know upfront and agree the scope before moving forward.
Q5. Do you offer design support if I don’t have CAD files? Yes — if you don’t yet have a complete design, our team can provide CAD support to get your enclosure production-ready. We can work from sketches, technical requirements, or modify existing models to ensure they meet manufacturing standards. This is particularly useful for startups without in-house engineers. Our design assistance covers sizing for electronics, wall thickness, ventilation, and compliance considerations, so you can move smoothly from idea to prototype.
Q6. Are your enclosures compliant with regulations? Yes — we design and manufacture with compliance in mind. Common standards we consider include IP ratings for dust/water resistance, flame retardancy (UL94 standards), and EMC shielding where required. While we don’t directly certify your product, we ensure enclosures are designed to meet the necessary requirements for CE, UKCA, or other certifications. We’ll also advise if your use case requires specific testing or materials to achieve compliance.
Q7. What materials do you use for enclosures? We use engineering-grade plastics such as PLA, ABS and PETG for prototypes, ensuring strength and reliability. For higher-volume orders, SLS nylon is also available to give you production-ready durability.
Q8. Can you handle both prototypes and larger production runs? Yes — we specialise in helping customers from the early prototype stage right through to full production. Whether you need a one-off enclosure to test fit and function, a small batch of 50–200 units for pilot projects, or a larger run of 500+ units, we scale with your needs. Many of our customers start with 2–3 prototypes, then move into batch orders once the design is validated. This way, you save time and money by working with a single partner throughout your product’s journey.
Q9. Do you ship across the UK? Yes — we ship to every part of the UK, including England, Scotland, Wales, and Northern Ireland. All orders are securely packaged to protect your enclosures in transit. Prototypes are sent via tracked courier for quick delivery, while larger batch orders are palletised or sent by freight where necessary. We also provide estimated delivery times at the point of order so you know exactly when to expect your parts.
