The processing cost of stamped aluminum alloy housings is influenced by a variety of factors.
Generally speaking, it’s medium to high. This is because stamped parts generally require molds, so mold costs are generally expensive. Of course, the overall cost level and key influencing factors are as follows:
Cost Structure Analysis
Material Cost
Aluminum alloy raw material prices are significantly higher than those of ordinary steel, and prices vary significantly between different grades (such as AL6061 and AL7075). Material costs typically account for over 60% of the total cost of a stamped part.
The high scrap rate in aluminum sheet stamping further increases costs.
Process Difficulty
Aluminum alloy stamping is prone to problems such as wrinkling and springback, requiring specialized mold design and process control, resulting in high mold maintenance costs.
The highly sticky surface oxide layer can easily damage the mold, increasing equipment depreciation costs.
Processing Efficiency
Compared to steel, aluminum alloy stamping is slower and requires specialized lubricants (such as volatile stamping oil) to reduce defects, indirectly driving up costs.
Horizontal Comparison
Compared with CNC machining: Stamping offers lower costs for high-volume production, but mold costs may be higher than CNC for smaller batches.
Compared with die-casting: Die-casting is suitable for complex structural parts, but the anodized yield rate for aluminum alloy die-casting is low, resulting in a poorer appearance and quality.
Cost Reduction Measures
Design Optimization: Avoid complex shapes and excessively deep drawing to reduce process complexity.
Material Selection: Select cost-effective grades (such as AL6061) and use pre-extrusion molding to reduce subsequent stamping costs.
Process Improvement: Utilize hybrid robotic loading and unloading to improve efficiency and reduce manual errors.
