The process involves setting molten metal in predesigned molds. Once the molten metal is left to solidify, it takes the shape of the mold. Casting can be achieved using veracious ferrous and non-ferrous metals and alloys.<\/p>\n<p>In metal casting, alloys are used to define the shape and design of the finished item. Additionally, there are many metal casting processes. Every type is different in terms of mold used or material design. This guide will help you know more about the basics of casting.<\/p>\n<h2><span id=\"Basics_metal_casting_processes\">Basics metal casting processes<\/span><\/h2>\n<p>Every metal casting process is unique. However, they revolve around the same principle. All the methods go through the same basic steps as shown below:<\/p>\n<h3><span id=\"Making_the_patterns\">\u00b7\u00a0Making the patterns<\/span><\/h3>\n<p>Before creating molds, casting manufacturers\u00a0must design the patterns. The process of fabricating mold patterns is called pattern-making. This is mainly done using a computer-assisted design system. The process involves creating the mold\u2019s dimensions and geometry, followed by packing materials around the pattern.<\/p>\n<h3><span id=\"Making_cores_optional\">\u00b7\u00a0Making cores (optional)<\/span><\/h3>\n<p>This is an optional process, depending on the `part you want to fabricate. Since many designs require a core, the manufacturer must place solid materials inside the mold cavity to create its interior surface.<\/p>\n<h3><span id=\"Molding\">\u00b7\u00a0Molding<\/span><\/h3>\n<p>This phase involves mold creation. Various materials, such as sand, plaster, or wax, can be used to create molds.<\/p>\n<h3><span id=\"Mold_filling\">\u00b7\u00a0Mold filling<\/span><\/h3>\n<p>This stage involves pouring molten metal into the mold. The metal is then left to cool and solidify before the mold is broken to remove the finished part.<\/p>\n<h3><span id=\"Finishing\">\u00b7\u00a0Finishing<\/span><\/h3>\n<p>The fabricated metal part may have cracks and rough surfaces from the mold used. This depends on the type of casting used. In this case, you may need post-processes to give the components a more refined surface finish.<\/p>\n<p><iframe loading=\"lazy\" title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/2CIcvB72dmk\" width=\"560\" height=\"315\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><\/iframe><\/p>\n<h2><span id=\"Types_of_Casting_Processes\">Types of Casting Processes<\/span><\/h2>\n<p>Metal casting is one of the most used and oldest metal fabrication methods in the world. However, recent advances in technology have led to the invention of many casting types. Accordingly, every process has its advantages and disadvantages. Here is a brief on different casting basics.<\/p>\n<h3><span id=\"1The_Basics_of_Sand_Casting\">1.\u00a0The Basics of Sand Casting<\/span><\/h3>\n<p>Sand casting\u00a0is a metal casting technique that uses sand impacted with clay and other bonding agents to form molds. The casting process is designed to reduce cracking and other defects. This means more flexibility and reduced shrinkage.<\/p>\n<p>After the mold is designed, molten metal; is poured and left to cool and solidify. After that, the mold is destroyed to remove the finished component. One of the benefits of sand casting\u00a0is that the sand can be reused in making other molds. This lowers the overall cost of production.<\/p>\n<p>However, sand casting produces metal components with rough surfaces and may need pos-treatments.<\/p>\n<h3><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-6539\" src=\"http:\/\/hengkemetal.com\/wp-content\/uploads\/2021\/08\/sand-casting.jpg\" alt=\"sand casting\" width=\"512\" height=\"235\" srcset=\"https:\/\/www.hengkemetal.com\/wp-content\/uploads\/2021\/08\/sand-casting.jpg 512w, https:\/\/www.hengkemetal.com\/wp-content\/uploads\/2021\/08\/sand-casting-300x138.jpg 300w\" sizes=\"auto, (max-width: 512px) 100vw, 512px\" \/><\/h3>\n<h3><span id=\"2The_Basics_of_Centrifugal_Casting\">2.\u00a0The Basics of Centrifugal Casting<\/span><\/h3>\n<p>The centrifugal casting process\u00a0is different from all other casting techniques\u00a0since it uses rotating molds. The process is known for its excellent quality and material soundness. Accordingly, it is one of the most basic casting methods.<\/p>\n<p>Centrifugal casting is further divided into vertical centrifugal casting\u00a0and horizontal centrifugal casting.\u00a0The difference between these two is the direction in which the axis rotates.<\/p>\n<p>When the mold is placed on an axis that rotates vertically, the process is vertical centrifugal casting. On the other hand, a mold that turns on a horizontal axis leads to horizontal centrifugal casting.<\/p>\n<p>Centrifugal casting is suitable for the manufacture of components with thin walls and consistent diameter.<\/p>\n<h3><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-6540\" src=\"http:\/\/hengkemetal.com\/wp-content\/uploads\/2021\/08\/casting-techniques.jpg\" alt=\"casting-techniques\" width=\"635\" height=\"452\" srcset=\"https:\/\/www.hengkemetal.com\/wp-content\/uploads\/2021\/08\/casting-techniques.jpg 635w, https:\/\/www.hengkemetal.com\/wp-content\/uploads\/2021\/08\/casting-techniques-300x214.jpg 300w\" sizes=\"auto, (max-width: 635px) 100vw, 635px\" \/><\/h3>\n<h3><span id=\"3The_Basics_of_Investment_Casting\">3.\u00a0The Basics of Investment Casting<\/span><\/h3>\n<p>Investment casting is also called precision casting or lost-wax casting. The process is the best metal casting technique if you want components with an excellent surface finish.<\/p>\n<p>The precision casting process\u00a0involves the use of molds made of wax and coated with refractory materials. Like all other methods, the process involves pouring molten metal into the predesigned mold, leaving it to cool and solidify, before removing the mold to get the final product.<\/p>\n<p>Since the process ensures a high degree of accuracy and surface finish, it may not require post-treatment. Additionally, investment casting is capable of producing metal parts with intricate shapes and designs. However, the process can be costly since it requires more labor and tooling.<\/p>\n<p>As shown, every casting method\u00a0has advantages and disadvantages. This means that you may want to look into each technique separately to determine the suitable one for your project.<\/p>\n<h2><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-6541\" src=\"http:\/\/hengkemetal.com\/wp-content\/uploads\/2021\/08\/every-casting-method.png\" alt=\"every casting method\" width=\"600\" height=\"538\" srcset=\"https:\/\/www.hengkemetal.com\/wp-content\/uploads\/2021\/08\/every-casting-method.png 600w, https:\/\/www.hengkemetal.com\/wp-content\/uploads\/2021\/08\/every-casting-method-300x269.png 300w\" sizes=\"auto, (max-width: 600px) 100vw, 600px\" \/><\/h2>\n<h2><span id=\"The_Benefits_of_Metal_Casting\">The Benefits of Metal Casting<\/span><\/h2>\n<ul>\n<li>Casting is one of the methods used in metal fabrication.
