With the rapid development of modern industry, metal extrusion technology has played a role in the application of lightweight, high strength and excellent precision parts. Whether in the aerospace and automotive industries, as well as in construction and electronic equipment, metal extrusion has demonstrated its irreplaceable value, providing excellent technical support for innovative product design and efficient production.
An overview of metal extrusion
Metal extrusion is an important metal forming process, by pressing metal materials through the mold under high pressure conditions to form parts with a specific extrusion surface shape. This process can effectively utilize the material characteristics to produce parts with high strength, light weight and complex structure.
Process characteristics of metal extrusion
High plastic deformation
In the process of metal extrusion, the material is subjected to strong pressure, flows under the condition of plastic deformation, and forms a predetermined shape through the mold.
Multiple process methods
Direct extrusion: The metal material is extruded through the die in the direction of pressure.
Extrusion pressure: The mold moves with the pressure, so the direct extrusion pressure is less.
Cold extrusion and hot extrusion: according to the processing temperature is divided into two, cold extrusion is suitable for delicate products, hot extrusion is suitable for complex shape parts.
High material utilization rate
Extrusion process can minimize material waste, especially suitable for the processing of expensive metals (such as aluminum alloy, titanium alloy, etc.).
productivity
The process is fast, and a large number of parts can be continuously produced to meet the needs of industrial scale.
Precautions for metal extrusion
Mold design
Mold design is the key, affecting the quality of the finished product, shape accuracy and production efficiency.
Process temperature control
Select the right extrusion temperature according to the type of metal to prevent cracking or deformation of the material.
Material selection
The extrusion material needs to have good ductility to ensure a smooth process.
Equipment maintenance
Extruders and molds need regular maintenance to avoid product defects caused by equipment problems.
Product post-treatment
Surface treatment of the product (e.g. anodizing, electroplating, etc.) as required to enhance durability and aesthetics.
