Detailed Step-by-Step Guide to the Extrusion Process
Understanding the extrusion process helps buyers appreciate the technological complexity and therefore value when investing in production lines.
1. Billet Preparation
Raw materials such as aluminum, copper, or thermoplastics are prepared by heating to specified temperatures. Ingots or pellets are melted and cast into billets that are ready for extrusion. Temperature uniformity and billet quality impact downstream extrusion outcome.
2. Extrusion Press Operation
The billet is positioned inside an extrusion press (often front-loading in South Korea) and forced through a shaped die. The die's cavity determines the cross-sectional profile of the extruded product, whether it's simple round tubing or complex multi-chambered aluminum profiles used in construction.
3. Shaping and Cooling
After being extruded, the hot profile requires immediate cooling to preserve dimensional accuracy and mechanical properties. Cooling may be done with air, water sprays, or specialized quenching lines.
4. Cutting and Finishing
Extruded profiles are cut to specified lengths using automated saws. Post-processing like anodizing, painting, or heat treatment is applied based on customer specifications. Final quality inspection ensures conformity with tolerance and surface finish standards.
