Technical plastic components

Carmo’s technical plastic components offer superb handling, weldability, performance, and durability in demanding applications, environments, and climates. Our product range includes e.g., HF weldable eyelets, valves, nozzles, and line supports used in critical applications.

Perfect for demanding applications

The robustness of our components makes them perfect for demanding applications exposed to e.g., pull-force from wind, salt water, and extreme climates. The key markets for our technical components are maritime, mining, agriculture and automotive, but our components are used across many industries and continue to appear in applications we had never imagined.

Wide product range

Our technical plastic components include products such as:

  • Weldable eyelets and attachments for use with PVC foils, PUR foils or coated reinforced materials
  • Valves for inflation, overpressure valves and vacuum valves
  • Threaded nozzles and caps for use with liquids or dry stuff

Carmo’s technical components are made in a number of different PVC grades (protected Carmo recipes), PE, PEHD.

HF weldable components

Our components are typically mounted using High Frequency Welding (also known as HF welding or RF welding) or ultrasonic welding. We also supply a line of dedicated machines for integrated punching, automatic feeding and welding of eyelets. For customers with existing barwelders, we offer a range of electrodes covering all our weldable components.

For small-scale production, prototyping and repairs, soft PVC can also be bonded with a commercially available PVC glue.

Delivery within days

Carmo has serviced the market for more than 70 years. Our products are sold throughout the world. We carry standard versions and colours of our components on stock for delivery within days – also in small quantities.

Custom designed plastic solutions

If you need a component with other specifications than we currently offer in our standard product range, we can custom design a solution for you.

We are experts at designing and producing robust components with specific requirements in close cooperation with our customers.

We have integrated Additive Manufacturing in our product development setup, and therefore offer prototypes in half the time compared to traditional prototyping.

Moulding processes

Carmo’s technical components are made by injection moulding: including insert moulding for metal-reinforced parts and 2K / multi-component moulding for multi-material designs.

Frequently asked questions

What we make & where it goes

What technical components does Carmo make?

Standardised technical components: HF-weldable eyelets (including the unique patented Carmo Metal Reinforced Eyelet, a one-step metal-plastic fusion construction with 3–4× the pull strength of a traditionally mounted metal grommet plus the wear resistance of metal), valves (inflation, pressure, overpressure, vacuum, relief), threaded nozzles, filler flanges, and snap grommets, produced in 1K, 2K, or 3K injection moulding using proprietary Carmo PVC recipes refined over decades. Beyond the catalogue, Carmo also develops OEM-specific variants and fully custom-designed technical components.

What markets do Carmo's technical components serve?

Maritime, industrial, agriculture, cleantech, and rescue markets: applications where components must extend end-product operating lifetime under harsh conditions: UV exposure, temperature cycling, mechanical stress, chemical exposure, immersion. Carmo has engineered components for these markets for decades.

Why it lasts

How does Carmo engineer technical components for durability?

By designing for the conditions the end product will actually meet: material selection matched to real-world conditions, design for durability, and testing built on decades of practical experience. The goal is components that extend end-product operating lifetime under harsh conditions. Our customer relationships in this segment commonly span 20 to 30 years, and Carmo’s own record backs the story: component designs from decades ago are still in production today.

What makes Carmo's weldable PVC eyelets different from metal eyelets?

A welded eyelet fuses with the fabric instead of clamping onto it, and the Carmo Metal Reinforced Eyelet takes that further: a stainless-steel insert (ASTM A240, Inox 304) fused directly into the plastic eyelet during a single-step moulding operation, delivering 3–4× the pull strength of a traditionally mounted metal grommet, plus the wear resistance of metal where the rope runs, with installation in a single operation using standard HF welding equipment. The construction eliminates the metal-plastic corrosion failure mode that limits service life in conventional brass eyelets. Used in tarpaulins, building wraps, boat covers, pool covers, truck and trailer covers, agricultural applications, tents and shelters, cinema screens, and large banners requiring high pull strength and durability.

Show all 11 questions
Is the Carmo Metal Reinforced Eyelet patented?

Yes: patented one-step metal-plastic fusion construction. The patent protects the principle that delivers the best of both worlds: the tensile pull strength of an HF-welded plastic eyelet combined with the wear resistance of a metal eyelet, built to outlast brass eyelets under UV, saltwater, freeze-thaw, and repeated cycling.

Compatibility & customisation

Which HF welding machines do Carmo's technical components work with?

It depends which components. For mounting Carmo’s HF-weldable eyelets and clip grommets into textile, banner and tarpaulin material, Carmo builds its own eyelet machine line, paired with Carmo HF electrodes as wear-replacement consumables:

  • CP9 / CP9S: automated, single-sided welding
  • CP8: automated, single- and double-sided welding
  • 6010: high-speed, for small eyelets
  • EP3: manual, entry-level
  • UG4: standalone setter tool

The broader HF-weldable range (inflation valves, threaded nozzles, filler flanges) is engineered to weld cleanly on your own welding line, with 50+ years of HF welding tradecraft built into the component rather than depending on Carmo-supplied equipment.

Does Carmo supply components in materials other than PVC?

Beyond Carmo’s custom-developed PVC recipes, most of Carmo’s technical components are also available in PVC/PU blends, and selected components in PP. If you have specific requirements for materials, welding, films, or substrate, Carmo’s engineering team will scope the fit with you.

Does Carmo offer OEM variants and custom-designed technical components?

Yes. Beyond the standard catalogue, Carmo develops OEM-specific variants (small geometry adjustments, material substitutions, branding changes, custom flange profiles) and fully custom-designed technical components. The same design, tooling, and moulding team that runs the catalogue range handles variant and custom work, so you don’t switch suppliers between standard and custom products. The tradecraft is the same end-to-end: decades of production experience applied to your specific need.

Ordering & continuity

Can I get Carmo technical components in small quantities, not just bulk?

Yes. Carmo’s scalable production model handles small-series runs economically as well as full bulk volume. For early-stage projects, prototype variants, or short-run validation builds, Carmo Print Moulding delivers functional samples in production material without a definitive tooling commitment. Larger orders run on definitive tooling. (Unit pricing is inherently higher on short runs than on volume orders; the economics of small-series production are settled during scoping.)

Why choose Carmo as a technical components supplier?

Three reasons converge for a technical-OEM buyer. First, integrated Danish manufacturing with the full chain from design through volume production under one engineering team, the same continuity medical buyers value applied to technical applications. Second, flagship IPs developed in-house (the patented Carmo Metal Reinforced Eyelet, proprietary PVC recipes, the Carmo Print Moulding process for rapid component variants) that you engage with directly. Third, customer relationships commonly spanning 20 to 30 years across maritime, industrial, agriculture, cleantech, and rescue markets, anchored by components engineered to extend end-product operating lifetime.

Why does Carmo produce in Denmark rather than source from lower-cost regions?

A deliberate choice. Highly automated production means the savings from offshoring would be modest, while keeping it in Denmark gives full control of quality and the ability to react fast to changing demand. For long-lifecycle technical components, that control shows up as consistency over decades. It also underpins Carmo’s environmental work: 60% of surplus production material recycled back into the supply chain, under an SBTi commitment to halve scope 1 and 2 emissions by 2030.
