Got a tough combination of molded components? Normally we weld, but sometimes the two materials are welding incompatible or the welding conditions are too extreme in temperature or time for the size of the part or complexity of the design. In that case, the option is to bond the materials. Bonding thermoplastics is a little tricky […]
Read MoreFriction has been used to weld parts for both new make and for repair for many decades. The friction welding family of processes encompasses many different variants, including rotary friction welding (inertia, direct-drive, and radial), linear friction welding, and more recently, friction stir welding (FSW). In each case, friction heats the material to a plastic […]
Read MoreMetallic glasses offer a unique combination of properties, including high tensile strengths (2000 – 4000 MPa) and elongations to yield (~2%). Bulk metallic glasses are those that can be cast into section thicknesses of up to several millimeters. These products have only been experimentally demonstrated over the last 15 years or so. Such bulk metallic […]
Read MoreThe majority of solid state welding processes use a combination of heat and deformation to accomplish an effective joint. Heating is seen as both enabling to the necessary forging for joining, and in addition offers a diffusional component which enhances joint quality and reliability. Solid state welding processes take advantage of a number of heat […]
Read MoreIn the most recent EWI Insights, there is an article highlighting a recent Friction Stir Welding (FSW) study with Polypropylene with nanocaly filler. This welding study showed that superior weld joints could be obtained in thick section thermoplastic composites. The weld strengths obtained for 6 wt% nanocomposite were significantly higher than those found during other […]
Read MoreUltrasonic Metal Welding is a unique process that has typically been limited to applications involving softer, high conductivity alloys. Skipping over the physics and metallurgy of the process; let’s just say that high-frequency vibrations are transferred to the work pieces via a set of ultrasonic tools to create a solid-state bond. For welding softer materials, […]

In medical device manufacturing, shrinking development timelines and budgets are at odds with simultaneous requests for improved product performance and functionality. How can you get your products to market faster and more reliably? EWI’s expertise in manufacturing technology for medical products includes battery development, welding of dissimilar and unique materials, polymer processing, nondestructive testing, and […]
Read MoreIf you are an engineer who loves applying research, developing new technologies, and helping fabricators throughout manufacturing find solutions to their material and process challenges, then EWI offers a great environment for your career. Our engineers are deeply passionate about their work. That claim might sound like hyperbole, but you don’t have to just take […]
Read MoreTwo EWI engineers are currently featured on the ASSEMBLY AUDIBLE podcast. This program, produced by ASSEMBLY magazine, explores the people, processes and technologies on the cutting edge of part-to-product fabrication. As a lead up to the ASSEMBLY Show later in October, Senior Engineer Miranda Marcus and Project Engineer Olga Eliseeva both gave interviews introducing their […]
Read MoreThe ASSEMBLY Show is a premier event for engineers and manufacturing executives. The conference showcases the latest assembly technology, equipment, and products, and hosts a series of workshops and presentations led by industry experts. The 10th annual show will take place in Rosemont, Illinois, October 25-27, 2022. This year, EWI engineering specialists will offer workshops […]
