Today, the world of the automotive industry is transforming at a rapid speed and adopting the trend of new tubing standards. The purpose is to introduce new products such as multilayer nylon tubing to replace the conventional pipe.
Usually, a multilayer nylon tube consists of three or more layers – which include an external and internal layer. It is a bit thicker and easier to work with – bringing together the benefits of both metal and plastic solutions. The system adopts polyamide (PA) 12 outer layer, PA adhesive layer, EVOH barrier layer, and EFEP conductive inner layer exposed in fuel. The inner layer offers significantly reduced levels of extractable substances from conventional plastic gasoline lines to minimize fuel consumption. So, such a construction may also increase the performance and reduce the overall assembly as well as the material costs – making the tubing more efficient and cost-effective for the consumer.
In addition, a multilayer nylon tube can reduce vehicle pollution or emission effectively to the environment to meet the higher environmental requirements. Likewise, multilayer tubes possess outstanding resistance when it comes to penetration performance – satisfying the EU emission standards stage VI and the six stages emission standards of vehicles in China.
However, as performance increases, the tubing designs are becoming more complex. Similarly, the technology known as the “Extrusion” is also becoming complex. At the front of such advancements in the automotive tubing, technology is the developments in the multilayer extrusion technology. It refers to the extrusion of multiple layers to produce a multi-layered pipe. Multilayer technology is employed mainly to enhance the functionality – to combine material that is applicable for welding – along with other properties such as lubricity.
As far as the production technology is concerned, it is widely used for the production of multilayer nylon tubes. Dekuma, the first-ever manufacturer in China to have launched such products or equipment, reaches a leading international level in this technology. The machine has state-of-the-art and outstanding performance, which means that the speed of stable production reaches 40 to 60 miles per minute that is quite comparable to the leading level. Following the Industry 4.0 standards, the advanced control system works effectively because of the self-developed monitoring application. Moreover, Dekuma’s multilayer fuel tube extrusion line is more automated, as well as consume less energy.
Unlike the other large-scale products, Dekuma has adopted a small integral design, which is useful for saving space and making the design more beautiful and compact. Dekuma multilayer nylon tube is used globally on a wide scale – for instance, in the fuel oil system of vehicles – that features a high performance, portable, and environmental protection pipe. The product has multiple layers, and the outside diameters are 6, 8,10,12,14, and 16mm. Furthermore, Dekuma multilayer nylon tubes have a higher cost-performance ratio. You will be surprised to know that the equipment has over 80% production capacity – making the price less than 50%. Its excellent customer experience makes consumers in China, and other parts of the world believe that this company provides customers with sophisticated solutions.
