Therefore plastics offer advantages of eliminating secondary finish operation. The advantages of using plastics are that they are lightweight, water resistant, durable, strong, economical and resistant to corrosion and chemicals. Plastic resins are continually evolving, becoming more suitable to accommodate modern product demands of being lightweight, durable, thermally conductive, and easy to manufacture. The advantages of using composites over metals highly depend on the application. Answered List the advantages of plastic over metal 2 See answers Ask your question. Traditionally, plastic itself is often a less expensive raw material compared to metal. We will keep updating this article on advantages and disadvantages of plastic over metal. Extremes of heat and cold can damage metal over time from continual expansion and contraction. The plastics industry only consumes 4% of the world’s oil production as feedstock. The major advantages of plastics over ceramics, glasses and metals are: 1. Table 2 summarizes the advantages and disadvantages of high temperature thermoplastics over metals. Click this link for more details on snap joints. The Advantages of Plastic over Metal As many industries become increasingly aware of the benefits of metal-to-plastic conversion, high-volume injection molding is quickly becoming the method of choice for part manufacture. The engineering team here at Custom Plastics has decades of experience in assisting companies during the design phase of projects and are experts at letting our customers know what types of designs can and cannot work for plastic extrusion and injection molding. Please add your comments, questions or suggestions on advantages and limitations of injection molded plastic parts in the comment box. Therefore plastic has the advantage of manufacturing parts with negligible wastage compared to metal parts. 1. Click this link for more details on snap joints. Unlike metals and ceramics, polymers don't require finishing to look good and last for a long time. For industries that need designing options, geometry and different kinds of textures, plastics are going to be the most suited materials. AIP explains the advantages of using plastics over metals in our infographic below, with special emphasis on how each industry benefits from using polymers. Certainly there will always be a need for metal, but for many industrial and consumer markets, plastic is becoming the material of choice for many convincing reasons, and the most important of which is cost reduction. Whereas metal parts are machined from relatively larger blocks. With the invention of plastic injection molding techniques, the interest of manufacturers in using plastics for medical applications has seen a huge surge. Lower cost: Generally, plastic gears are less expensive to produce than metal gears. Advantages of Plastic. AIP explains the advantages of using plastics over metals in our infographic below, with special emphasis on how each industry benefits from using polymers. Concepts like single-use medical examination kits which make use of sterilized plastic instruments, as well as dis… The manufacturing of plastic parts is budget-friendly. Read on to learn all about it from the plastics professionals. But cost and weight are not the only factor that industries are using more plastic parts in their products. are used to get samples quicker. Ask any metal manufacturer the same question and you will get a list of reasons why metal is superior. Therefore plastic part weight and cost are less compared to metal parts. Along with so many advantages, Using plastic parts instead of metal can have following limitations as well. They have higher life dependency. Plastic resins are continually evolving, becoming more suitable to accommodate modern product demands of being lightweight, durable, thermally conductive, and easy to manufacture. New plastic materials offer strength and stiffness comparable to steel, and innovative processing capabilities allow us to machine plastic parts with tight tolerances. This results in much reduced maintenance and repair costs. For example, Latest manufactured vehicles are low in weight compared to old vehicles. This plastic conversion model that the lighting industry is moving forward with can easily be applied to many industries across the globe. The following properties of plastic make it the material of choice for making many articles: Plastics are non-reactive: Most of the metals get corroded by air and water. Which has relatively lower cycle time. This method is used for the separation of non volatile compounds. Remote controls, computers, TVs, kitchen appliances – you name it and chances are it’s made of plastic. This plastic conversion model that the lighting industry is moving forward with can easily be applied to many industries across the globe. As a result product assembly time and cost is reduced. These advantages are quantified in Table 1.2 where, for example, it is seen that nylon has a specific gravity about one-sixth that of … Therefore, it is used for making many utensils and storing various chemicals. 1. But cost and weight are not the only factor that industries are using more plastic parts in their products. So they cannot be corroded easily. Injection molding tool development has longer lead time. Plastic bumpers absorb shock, plastic dashboards and door panels are a little kinder on your head during a wreck, and plastic fuel tanks minimize explosion risks.
