advantages of plastics over metals

Additionally, the manufacturing process of plastic utilizes faster cycle times compared to metal, achieving lower production costs of plastic components versus metal components. Design Flexibility. Freedom to tailor the stiffness and strength of a part by varying the thickness and fibre orientation; 2. So they cannot be corroded easily. Nearly any transportation-related field can also benefit by investigating the advantages of metal replacement plastics: shipping containers, railroad manufacturing, heavy trucks and RVs, aircraft applications, and more. Plastics typically come from non-renewable resources. 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 … Plastic products play a major role … One of the main advantages to using plastic as a construction material is the cost to produce and use plastics – it is less expensive than most other materials. Plastics are more durable than ceramics, glasses, and metals. Weight Advantages. 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. Rubber over metal- Molding of a flexible rubber substrate on top of a metal cast/part. Even with these gains on the auto front by metal makers, plastics continue their onslaught onto the automakers' components menu. In this article we will discuss various advantages and disadvantages of plastic over metal parts. It is clear to see that converting from a traditional metal luminaire system to one composed mostly of plastic dramatically reduces the amount of assembly required to create the final product. Plastics manufacturing process has advantages of Integrating assembly features in plastic parts itself. Plastics can not be used for very high and low temperature ranges. Because various metal parts in old vehicles are replaced with plastic parts. Assembly features such as snap are used to join plastic parts. The advantages of using composites include: 1. Whereas plastics have inherent corrosion resistance properties and required aesthetic finish can be achieved during injection molding. Plastics have actually been used in cars since the 1950s, but it’s the latest innovations that are really changing the industry for the better. You can expect 25 to 30% cost saving with metal-to-plastic conversion. List of the Disadvantages of Plastics. Metals generally provide the following advantages over plastic fabrication: Heat resistance: Metals typically have a higher melting-point and are less likely to degrade under elevated temperatures. Buckets that are constructed from rigid and abrasion-resistant nylon are ideal for their ability to stand up to extreme abuse. Apart from weight and cost, plastic parts have the following advantages compared to metal parts. Reduced waste. This process has an advantage of manufacturing complex features, geometries and integrating multiple metal parts in one plastic part. The manufacturing of plastic parts is budget-friendly. Log in. This is the main reason that plastic is commonly used in construction. 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. If you continue to use this site we will assume that you are happy with it. Superior design flexibility. High temperature plastics also provide weight savings in many applications (e.g., automotive) and as a … Benefits of Plastic Over Metal. Polymer materials handle far better than metals in … With the invention of plastic injection molding techniques, the interest of manufacturers in using plastics for medical applications has seen a huge surge. Requires less heat (than metal or glass) for giving a shape. Below, we’ll look at the advantages that plastic parts can offer over metal ones, in the right applications. Plastic over metal- Molding of a plastic substrate on top of a metal cast/part. AIP explains the advantages of using plastics over metals in our infographic below, with special emphasis on how each industry benefits from using polymers. Thermoplastics parts are lighter in weight. So how does the process of overmolding actually work? Specifically within the lighting industry, we are seeing many manufacturers of luminaires converting their metal housing and heat sinks into single injection molded parts using modern engineering-grade polymers that have similar properties as aluminum.
