Joining Plastic to Metal Lightweighting trend drives engineers on quest to join dissimilar materials. This process also starts with circles that are cut from sheet. It’s difficult for upstart materials to compete with sheet metal on cost, … Parts and pieces continue to get, and the requirements for assembly needed a process that allowed for a variety of materials to be connected utilizing plastic as a catalyst. Screws are examples of nonpermanent fasteners, since they can be removed, replaced, and reused. This article covers various types of sheet metal joining techniques, their advantages, disadvantages and applications. Plastic sheeting is notoriously hard to join - tape is messy and glue won't stick. Heat staking plastic or swaging both result in a tight and reliable mating of plastic and a component. Joining methods Permanent fixings ... Epoxy resin (ER) - Used for joining woods to other materials such as metals and plastics. There are multiple processes for welding two plastic components together, much as there are with metals. Understanding of the various joining technologies that exist for multi-material metal-to-metal, polymer-to-polymer, and metal-to-polymer hybrid structures is consequently important. and call a representative at 1-586-949-2355. This website requires certain cookies to work and uses other cookies to A tapped hole is required on the end of one profile and an access hole, for bolt tightenin… However, each process is different, meaning that each is only good for specific applications. The wall thickness of pipe used is determined by the pipework designer, taking into account the internal pressure, mechanical stresses to which it is subjected (i.e. Solvent bonding involves coating plastics with a solvent and clamping them together. Each joining technique has advantages and disadvantages. Metal Stitching, It's Fast, Simple, and Cost Effective. Therefore, before understanding how a steel fabricating enterprise can help you and your business, it is necessary to understand both the heat staking and swaging processes and to understand the best practices for either approach. Welding is an effective method of permanently joining plastic components. This is the case for both metal-only hybrid structures and for structures where metal components are complemented with plastics/composites. Heat swaging, alternatively, is a process designed for direct framing. Set up a workspace in a ventilated area to protect against dust and fumes. This is also easy for smaller volumes. GRP (Glass Reinforced Plastic) is commonly used offshore on smaller service/potable water lines. Always make sure that there is suffi-cient distance between the edge of the fastener’s hole and the part’s edge. A laser joining technology for direct-bonding a metal and a plastic, named laser-assisted metal and plastic (LAMP) joining, has been developed to overcome the above drawbacks. However, while different, both staking and swaging rely on a combination of time, heat and force. used joining methods for assemblies that must be taken apart a limited number of times. To perform an induction weld, plastics are placed around a metal object and run through a magnetic field, which causes the plastics … Linear diode laser beam direct joining of metal and plastic and the formation of bubbles [4] The LAMP method was also used by Lambiase & Genna to join 1 mm thick AISI 304 stainless steel with 2 mm thick polycarbonate using a 200 W diode laser [7]. Ultraviolet bonding utilizes a curing process with high-intensity ultraviolet lighting that … The vibrations create friction, which heats the plastics and welds them together. Joining Methods of Sheet metal and Plastic.. Posted by Rikas on October 25, 2009 at 10:36pm in Mechanical Engineering; View Discussions ; Hello all, I need to design a economical, robust joint between a sheetmetal of thickness 2.5 mm with a plastic part of wall thickness 2.5 mm. Vibration welding involves joining two plastics and vibrating one of them. Materials joining methods 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. Each method is associated with equipment, labor and other costs that you most consider. Joint reliability depends on joint type, sheet metal material and its manufacturing process. Solvent Bonding. All Rights Reserved BNP Media. They are adhesive bonding, mechanical fastening, and welding. Several joining techniques are commonly used for hybrid joints between metal and polymer workpieces. As the post is heated, it is pressed or staked downward to form a new shape and securing it to the mating component.
