型材批发厂家介绍，用挤压方法生产型材的工艺。挤压型材分空心型材和实心型材两大类。空心型材是指横断面有一个或多个封闭通孔的型材。挤压型材的品种和规格已超过3万种，尤以铝型材为最多，达2.4万余种。其次是铜型材、镁型材和型钢以及塑料型材。
The process of extrusion method is introduced. Extruded profiles are divided into two categories: hollow sections and solid profiles. A hollow section is a section with one or more closed holes in a cross section. There are more than 30 thousand kinds of extruded profiles and specifications, especially aluminum profiles, with more than 2.4 million. Secondly, copper profiles, magnesium profiles and type steel and plastic profiles.
实心挤压型材约占全部挤压型材品种规格的65%，而异形断面型材又占实心断面型材的大部分，其次是空心挤压型材，如铝门窗型材，塑料门窗型材等。同其他方法诸如轧制、模锻生产的型材相比，挤压型材的强度较高。挤压工具更换比较简单，可小批量生产。采用挤压法生产复杂形状制品，尤其是断面变化很大的制品，可以大大减少机械加工量，减少金属损耗，提高零件和结构的使用性能。
The solid extruded profiles account for 65% of the total extrusion profiles, while the special-shaped section sections occupy the majority of solid section profiles, followed by hollow extruded profiles, such as aluminum door and window profiles, plastic door and window profiles and so on. Compared with other methods, such as rolling and die forging, the strength of extruded profiles is higher. The replacement of the extrusion tool is relatively simple and can be produced in small quantities. The extrusion process for complex shape products, especially those with large cross-section, can greatly reduce the amount of mechanical processing, reduce metal losses and improve the performance of parts and structures.
