Low pressure casting<\/strong>Also known as anti-gravity low-pressure casting is the name of its casting method is through the gas pressure against gravity casting molding, as shown in the figure on the right: through the sealing of the crucible into the gas (usually 0.06 ~ 0.15MPa)), the aluminum liquid in the role of pressure through the middle of the pipeline, the product for the molding of the casting, pressure for a certain period of time, the aluminum water cooled in the mold cavity molding, through the discharge of the gas pressure, open the mold The mold is opened by discharging the air pressure and the product is taken out.<\/p>\n<\/div>\n\n\n\n gravitational casting<\/strong>Refers to the aluminum water through the action of gravity casting \u2192 filling \u2192 solidification contraction \u2192 castings, this process is called gravity casting, gravity casting is a development of a relatively long time aluminum alloy casting process, more different molds are divided into non-metallic type gravity casting (refers to not allow for metal molds usually referred to as sand casting), metal-type heavy casting (refers to the use of metal molds)<\/p>\n<\/div>\n<\/div>\n\n\n\n Low pressure casting<\/strong>There is a 0.06\uff5e0.15MPa by air pressure for mold filling and casting.<\/p>\n\n\n\n gravitational casting<\/strong>It is only by gravity that the mold is filled, not relying on external pressure, but on the weight of the metal liquid itself for flow and filling.<\/p>\n\n\n\n Low pressure casting<\/strong>Due to the external pressure, the flow speed of the metal liquid can be better controlled under pressure, the product is fuller and the surface quality is higher. Aluminum water crystallizes under pressure, the casting has a higher density and a smoother surface.<\/p>\n\n\n\n gravitational casting<\/strong>Since it can only flow naturally, the ability to control the flow of the liquid metal is weak, and the surface is poorer than that of low-pressure casting, and it is usually only possible to make thick-walled products.<\/p>\n\n\n\n Low pressure casting is commonly used in demanding high-end automotive, aerospace and other industries because of its high precision and quality control. Gravity casting is often used to produce relatively thick products because of its low cost and simple process.<\/p>","protected":false},"excerpt":{"rendered":" Low-pressure casting and gravity casting are aluminum alloy casting process, low-pressure casting is also known as anti-gravity casting, low-pressure casting. Low pressure casting is also known as anti-gravity casting, low pressure casting. The difference between it and gravity casting is mainly reflected in the following aspects. The difference between the casting principle of operation: the difference between the casting principle of operation: low-pressure casting is also known as anti-gravity low-pressure casting, so the name of the casting method is through the gas pressure against the gravity casting molding, as shown in the figure on the right: through the sealing of the crucible injected into the gas (usually 0.06 ~ 0.15MPa)), the aluminum liquid in the role of pressure through the middle of the pipeline, the product for the molding of the casting, holding pressure for a certain period of time, the aluminum water cooled in the mold cavity, the aluminum water cooled in the mold cavity. Aluminum water in the mold cavity cooling molding, through the discharge of gas pressure, open the mold, remove the product. Gravity casting refers to the casting of aluminum water by gravity \u2192 filling \u2192 solidification and contraction \u2192 casting ...<\/p>","protected":false},"author":1,"featured_media":412,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":[],"categories":[21],"tags":[47,49,48,89],"class_list":["post-283","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-about-news","tag-low-pressure-casting","tag-die-casting","tag-gravity-casting","tag-aluminium-alloy"],"_links":{"self":[{"href":"https:\/\/www.hexinmusu.com\/en\/wp-json\/wp\/v2\/posts\/283","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.hexinmusu.com\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.hexinmusu.com\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.hexinmusu.com\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.hexinmusu.com\/en\/wp-json\/wp\/v2\/comments?post=283"}],"version-history":[{"count":0,"href":"https:\/\/www.hexinmusu.com\/en\/wp-json\/wp\/v2\/posts\/283\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.hexinmusu.com\/en\/wp-json\/wp\/v2\/media\/412"}],"wp:attachment":[{"href":"https:\/\/www.hexinmusu.com\/en\/wp-json\/wp\/v2\/media?parent=283"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.hexinmusu.com\/en\/wp-json\/wp\/v2\/categories?post=283"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.hexinmusu.com\/en\/wp-json\/wp\/v2\/tags?post=283"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}![\"\"](\"https:\/\/www.hexinmusu.com\/wp-content\/uploads\/2024\/08\/low-pressure-casting.gif\")
