Thankfully, technological advancements and achievements led to more unique and economically efficient thermal presses, making both heat staking and swaging more feasible. While picking the right plastic adhesive can make you wish you’d majored in chemistry, welding is arguably the better method for fusing two plastic components. Lines of 2 inch or larger are usually butt-welded, this being the most economic, leak-proof method. A mechanical method for joining plastic and metal to create hybrid automotive front-end assemblies has been developed by BASF AG in Germany. In this method of joining, joints can withstand shear, tensile and compressive stresses, but do not have good resistance to peeling. In addition to thread profile changes, some manufacturers have taken the screw design even further to improve on various factors. Heat staking plastic or swaging both result in a tight and reliable mating of plastic and a component. This technique is mainly used for joining thermoplastic films with a thickness of less than 0.5mm. While for seat structures, this has translated mainly into the use of thinner, higher-strength steels up to now—hybrid material structures have also been studied widely in recent years. Two methods used to join of materials permanent and semi-permanent, Different materials can be joined in many different ways depending on the joint needs to be permanent or semi-permanent. Today, design engineers have many options to choose from when joining metal to plastic. While bonding ABS can be done with a variety of types of plastic adhesives (plastic glues), a few of the most common include cyanoacrylate, 2 component epoxy, structural acrylic, and UV curable adhesives. Primarily, the machine heats up a plastic post protruding from one item and through what’s called a mating component. This method is now used to produce many straight sided vessels and gives no need to form and join a separate base. Ultrasonic staking is like a riveting application for moulded plastic components, but without the disadvantages of separate fasteners. Joint reliability depends on joint type, sheet metal material and its manufacturing process. Adhesive bonding joins parts using bonding chemicals. In plastic to metal joining applications, advanced epoxy, silicone, cyanoacrylate and UV cure adhesive systems are easy to apply, have convenient cure schedules and offer high performance in difficult environments. Heat staking and swaging both evolved out of necessity. Where the limitations of ultrasonic plastic welding make a job impractical, some other ultrasonic joining techniques may be applicable. Unlike automakers, which are turning to aluminum, carbon-fiber composites, magnesium, plastic and other lightweight materials, steel still rules in the world of refrigerators, dishwashers and dryers.
