HC Plastics News: The unique shoemaking materials of Huntsman Polyurethanes are at the heart of innovative footwear manufacturing methods that have the potential to change the way footwear is produced worldwide. The Spanish company Simplicity Works has teamed up with Huntsman Polyurethanes Co., Ltd. and Desma Footwear Company to create the biggest change in the field of footwear assembly in the past 40 years, and has developed a revolutionary new method of footwear production for hope. Manufacturers that produce products closer to European and North American customers offer the possibility to change the rules of the game. In collaboration, the three companies created a highly automated, cost-effective way to bond two-dimensional components together to form a seamless three-dimensional upper. Simplicity Works' patented 3D bonding technology is the world's first technology. This process requires no sewing and takes less time, and it takes only a few seconds to connect all the parts of the shoe at the same time. Compared to traditional shoe-making technology, this new technology is faster and cheaper and can be customized to meet your needs. This technology has proven to be very popular among many large brand footwear companies because it helps them align local production costs with countries with low labor costs. This 3D bonding technology uses the innovative 3D mold design created by Simplicity Works; injectable materials specifically designed by Huntsman Polyurethanes; and the most advanced DESMA injection molding machine. In the first step, a single upper assembly is placed in the mold and placed in a slot separated by a slit channel, somewhat like putting the puzzle together. After that, each part is pressed into place using a counter mold. The high-performance polyurethane material developed by Huntsman is then used to inject the channel network between the upper components in one shot. The end result is the upper, which is held together by an elastic polyurethane structure that is both practical and stylish. In order to obtain a high-quality polyurethane foam structure, a durable upper, and a high-definition texture, Simplicity Works and Huntsman have extensively studied new processes and materials. Available in a variety of colors, the texture of the bonded polyurethane threads (or linear) can be varied, which means the designer can choose a lustrous or matt texture and a variety of other similar textiles. The combination of surface processing methods. 3D bonding technology is suitable for a wide range of footwear manufacturing and is compatible with a wide range of synthetic and natural materials, making footwear manufacturing outside of countries with low labor costs more cost competitive. Since no seams are required, the entire production process is less labor intensive and reduces production costs. Since there is no material superimposed portion, material consumption is reduced and material cost is reduced. From a consumer perspective, this technology has other advantages. There are no knitting or sewing threads for the shoes, no material flanging, smaller friction points and pressure points, and more like a pair of socks. Shoes are also more waterproof due to the absence of pinholes or permeable seam lines. The launch of Simplicity Works' 3D bonding process has brought the three partners to their peak in six years, and they are fully confident that this technology can subvert the traditional way of producing footwear. Adrian Hernandez, CEO of Simplicity Works and inventor of 3D bonding technology, said: “I have worked in the footwear industry for 25 years and have worked in different countries and continents, so I am very familiar with the complexity of traditional footwear production. Years ago, I realized that there was a way to simplify the manufacturing of footwear. I hope to correct the geographical balance of the footwear industry in terms of labor costs, so I came up with a new process that can make footwear production in North America and Europe more. Cost-effective, but also increase consumer comfort. I took my patent concept and started looking for partners to make my vision a reality; this led us to the company with Huntsman and Desma (DESMA) Cooperation." He continued: “In the past six years, our three teams have worked closely together to bring together their expertise and expertise to create a process that has the potential to transform the footwear industry. The timing is perfect. Currently, An estimated 80% of European footwear imports come from low-cost labor countries. Faced with rising costs in these regions, many footwear companies are looking to transfer production back to Europe and North America. Our 3D bonding technology enables them to do this. One thing is to create shoes that are more economical than those made in Asia, and this has not taken into account the savings in transportation costs." Johanvan Dyck, global OEM business development manager for Huntsman Polyurethanes, said: “Simplicity Works is very demanding, but we like to challenge! They want us to develop a reactive, injectable polyurethane system that requires excellent bonding. Performance and high product flow. The material must also provide comfort and cushioning, as well as superb finishing aesthetics. With our many years of experience, we set out to develop the right technology. This is a long process that needs to be carried out Improvements, but we now have a revolutionary technology platform that can be bonded on one or both sides. Our work in this project allows us to expand our long-term relationship with DESMA and Simplicity Works builds a new alliance - Simplicity Works is a corporate team dedicated to changing the future of footwear manufacturing." Christian Decker, CEO of DESMA, said: “We are the global technology leader in the footwear industry and have been providing manufacturers with advanced machinery and molds for more than 70 years. Smart, innovative, sustainable, automated footwear production The principle is the core of our business, which makes us a natural partner of Simplicity Works. We are very happy to participate in this project, working with the Simplicity Works and Huntsman Polyurethane team to provide a kind of workforce for footwear manufacturers. A more costly way to manufacture high-end footwear in a more economical way." Simplicity Works' 3D bonding technology is very flexible, which means that footwear manufacturers can choose to use it as the primary joining technology or combine it with traditional stitching methods for functional or decorative purposes. Simplicity Works has patents for its technology, and engineers use CAD software to design products for customers. Once the product is designed, Simplicity Works will develop all the tools and molds needed for footwear production. This proprietary technology was then transferred to the manufacturer and worked with Huntsman and Deshima to determine the mechanical and polyurethane specifications. 3D bonding technology can significantly reduce production costs, SimplicityWorks charges a certain percentage of technology usage costs, DESMA provides all the necessary mechanical and automation systems, and Huntsman offers the best polyurethane materials with 3D bonding technology. produce. †Simplicity Works' 3D bonding technology, with its incredible versatility, is likely to add value outside the footwear industry, and the company is exploring opportunities to make apparel, accessories and even furniture using this versatile manufacturing method.
