What is Aluminium extrusion Process?<\/strong><\/h2>\n

Aluminium Extrusion Process involves the transformation of the raw aluminium billets into specific cross-sectional shapes and profiles by forcing the billet through the extrusion die. This versatile and cost-effective process is used to create a wide range of products with intricate design and has applications in various industries, including construction, automotive, aerospace, shipbuilding, furnishing, road structures, photovoltaics, bridges,electronic and consumers goods.<\/p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row admin_label=”row” _builder_version=”4.16″ background_size=”initial” background_position=”top_left” background_repeat=”repeat” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_column type=”4_4″ _builder_version=”4.16″ custom_padding=”|||” global_colors_info=”{}” custom_padding__hover=”|||” theme_builder_area=”post_content”][et_pb_text admin_label=”Text” _builder_version=”4.21.0″ background_size=”initial” background_position=”top_left” background_repeat=”repeat” global_colors_info=”{}” theme_builder_area=”post_content”]

Types of Aluminium Extrusion Process<\/strong><\/h2>\n

There are two main types of aluminium extrusion processes: direct and indirect<\/strong>.<\/p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”1_2,1_2″ admin_label=”row” _builder_version=”4.16″ background_size=”initial” background_position=”top_left” background_repeat=”repeat” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_column type=”1_2″ _builder_version=”4.16″ custom_padding=”|||” global_colors_info=”{}” custom_padding__hover=”|||” theme_builder_area=”post_content”][et_pb_text admin_label=”Text” _builder_version=”4.21.0″ background_size=”initial” background_position=”top_left” background_repeat=”repeat” global_colors_info=”{}” theme_builder_area=”post_content”]

Direct Aluminium Extrusion Process<\/strong><\/h3>\n

Direct Aluminium Extrusion, also know as forward extrusion, is the most common extrusion method. In this process, a heated billet of aluminium alloy is placed in a container and then pushed by hydraulic ram through a stationary die. The pressure exerted by the ram forces the malleable aluminium to take on the shape of the die opening as it passes through. This process allows the creation of a wide range of complex shapes and provides a high-quality surface finish<\/p>\n

Indirect Aluminium Extrusion Process<\/strong><\/h3>\n

Indirect aluminium extrusion manufacturing process, or backward extrusion, is an alternative method. The billet remains stationary while the container and die assembly move. A hollow ram pushes the die against the billet, forcing the aluminium through the die opening. This process generates less friction, requires less energy and produces less heat, allowing better control of dimensional accuracy, material properties and grain size. However, it has limitations in terms of the maximum size of the die profile. It can also result in reduced surface quality due to migration of surface contaminants from the billet.<\/p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row admin_label=”row” _builder_version=”4.16″ background_size=”initial” background_position=”top_left” background_repeat=”repeat” custom_padding=”1px|||||” global_colors_info=”{}” theme_builder_area=”post_content”][et_pb_column type=”4_4″ _builder_version=”4.16″ custom_padding=”|||” global_colors_info=”{}” custom_padding__hover=”|||” theme_builder_area=”post_content”][et_pb_text admin_label=”Text” _builder_version=”4.21.0″ background_size=”initial” background_position=”top_left” background_repeat=”repeat” global_colors_info=”{}” theme_builder_area=”post_content”]
