Making inflatable products is a complex process, as applications such as white-water rafts, military attack boats, airplane escape chutes which land escaping passengers in water bodies, oil booms and many more such products are 3-dimensional products that need to withstand high impact and abrasive use.
When it comes to the manufacturing process for sealing air-filled products, the durable seal is virtually the most important aspect of the manufacturing process. Without strong seals, leaks can develop, compromising safety, among other issues.
Besides the choice of fabric or technical textile to manufacture such applications like thermoplastic polyurethane (TPU) and heavy-coated PVC; the weld process is critical to make airtight marine / water-based applications ‘fail-proof’ and 100% secure.
Hot Air and Hot Wedge welding technology is capable of welding any thermoplastic material.
Using Hot air welding to manufacture such air tight products reduces production time and is a far superior option to gluing joints and seams together.
Magnum Resources offers best-in-class automated industrial welding solutions for the manufacture of marine applications such as oil booms, inflatable boats and other aqua-based air-tight applications, with a world-class range of welding machines from Miller Weldmaster.
Miller Weldmaster’s T300 Extreme Curve (hot air and hot wedge welder) and T600 Extreme Curve are great examples of world-class industrial welding machines that are adept in joining seams for equipment and apparatus that requires air tight, fail-proof applications such as marine equipment, boats, oil booms etc.
Hot air welding machines do the job akin to sewing machines that use hot air to meld fabrics rather than thread. A variety of seams are possible using a hot air welder such as overlaps, overlaps with cover strips (or two cover strips), butt seams, channel seams, cover strips, hems with pockets, double folds to name a few.
Hot air welding creates seams that are often stronger than the production material being used.
Miller Weldmaster’s T300 Curve and T 600 Curve Extreme automatic welding machines create airtight and waterproof seams unlike when you sew or poke holes in fabric.
These Hot air welding systems allow changing the weld width several times during the manufacturing process, lending a degree of flexibility to the manufacturing process.
Hot Air Welding Machines are the very backbone of industrial fabric welding, delivering unparalleled precision, efficiency, and reliability.
Miller Weldmaster’s Automated Welding machines use advanced technologies to control heat, pressure, and speed to bond thermoplastic materials like PVC, polyurethane, and other coated fabrics.
Typically, you need a combination of Miller Weldmaster’s T 300 Curve, T600 Curve Extreme to weld inflatables, boats, and Miller Weldmaster’s RFlex (radio frequency welding system) to weld the boat’s valves and ports etc.
Radio frequency (RF) welding is one of the best methods to use for sealing air-filled products, and is done by temporarily destabilizing the entire thickness of the surfaces to be joined, then immediately applying pressure to those surfaces to create a new, fused seam.
These radio frequency (RF) enabled welding processes typically use tooling dies to create the shape and functionality of the product. Tooling dies are custom made for each product and are designed to be used specifically with either radio frequency welding, and high-frequency welding.
RF welding is an ideal solution when creating seams that need to be airtight—when it comes to air containment solutions like inflatables, oil booms, underwater insulations etc.
RF welding helps you seal air-filled products that need to be water tight. This process allows the operator to destabilize the surfaces' thickness before applying pressure to create a new, fused seam.
RF welding allows the operator to address already-welded areas more than once, unlike other welding processes. Besides, there is no risk of poking holes or causing damage to the fabric being used under production.
This advantage of high-frequency welding process combines time, RF energy, and pressure to create a robust, uniform weld throughout the area to be sealed. The air tight product won't need not require adhesives or by-products when using RF welding.
RF welding enables operations to weld curved shapes and any difficult areas where other welding technologies may encounter restrictions.
Miller Weldmaster’s RFlex welding system is great at producing strong, durable, even-shaped welds. RFLEX has wide applications across a range of materials of varying thicknesses. RFLEX’s reliable and repeatable technology gives manufacturers waterproof and air-tight welds with nearly invisible seams, even on multiple layers of fabrics.
You can rely on the seams created by Miller Weldmaster’s Automated welding solutions to be strong enough to inflate, not leak, and last almost a life time.
