Why injection moulding is essential for in-ground installations.
When we get asked about how to install LED tape into driveways, decking, or swimming pool perimeters, the first thing that we explain is that standard LED tape is not suitable. Even IP67 strips will not be designed to survive in ground conditions. Injection moulding is the only reliable method to ensure your lighting remains fully sealed, giving you the best protection from all conditions.
In this blog, we will explain why injection moulding is vital, how it works, and why it is the key step in achieving an installation that is built to last in your tricky, in-ground applications.
Why standard IP67 strips need extra protection for in ground installs
While our Neon Flex tape is built for outdoor conditions, installations where the strip is embedded in concrete, paving, or decking will require an even higher level of protection.
Without proper sealing:
- Water or condensation can enter through the connection points causing corrosion or failure
- Dirt, grit, and chemicals (like chlorine or salt) can degrade the LEDs and other internal components
- Mechanical pressure from foot or vehicle pressure can damage connections.
This is where injection moulding comes into play. It ensures the end caps and tails are completely sealed and reinforced, making it suitable for the toughest conditions.
What is injection moulding for LED tape?
Injection moulding is a process where high-strength, UV-stable resin is pressure-injected around the LED tape’s connection points and end caps. This resin sets into a solid, watertight barrier that permanently seals any weak points in the strip.
Key benefits of injection moulding:
- Fully water-resistant ends: Allowing it to withstand rain, flooding, and other heavy water flow.
- Enhanced durability: The solid resin adds extra mechanical strength, protecting against pressure from being installed in concrete or between paving stones.
- UV and chemical resistance: Designed to handle exposure to sunlight, chlorine, or saltwater without cracking or yellowing.
- Professional finish: Injection moulding gives a clean, permanent seal, unlike rubber end caps that rely on silicon and are far less pleasing to the eye!
Why is injection moulding non-negotiable for in ground installs?
In-ground installations are some of the harshest environments for LED lighting. Between moisture, dirt, mechanical load, and temperature fluctuations, there is no room for weak sealing.
Injection moulding:
- Prevents water ingress: The number one cause of LED failure outdoors is water entering via the connection points. Injection moulding removes this risk.
- Withstands physical stress: Whether installed in a driveway, decking, or pathway, the lighting must endure weight and pressure; something a resin-sealed connector will handle.
- Ensures longevity: Without proper sealing, even the best quality LED tape will fail. Injection moulding will extend the lifespan, giving you full warranty and peace of mind.
Where is injection moulded needed?
Our injection moulded tapes are not only a popular option when it comes to the professional finish and durability of the tape, but it is also needed for the warranty in certain areas such as:
- Swimming pool perimeters: Giving a stunning visual to really highlight the pool and draw attention to it.
- Decking and patios: Adds a sleek glow to garden edges and walkways.
- Driveways and pathways: Designed to handle heavy foot traffic or even vehicles driving over – we would recommend a heavy-duty profile along with the injection moulding for this though!
- Water features and fountains: Ideal for high moisture areas to add a degree of ambience.
FAQs: Injection Moulding for LED Neon Flex
- Why can’t I just seal it with silicone myself?
DIY sealing methods often fail under pressure or long-term exposure. Injection moulding creates a permanent, industrial-grade seal that is guaranteed to last. - Can I cut the strip after its injection moulded?
No, cutting would break the sealed protection. We custom cut and injection mould your strip to your required lengths. - Will injection moulded LED tape still be flexible?
Yes, only the ends and connectors are rigid. The main body of the neon flex remains flexible. - Is injection moulding suitable for RGB and RGBW strips?
Yes, our resin sealing process works across all neon flex types, including RGBW, which often needs straight-entry connectors for best reliability.
