The relationship between die casting process and cost is very close, and the selection and optimization of process directly affects the production cost. The following are some key factors and their impact on cost:

1. Material selection
Material cost: The cost of different materials varies greatly. The prices of common materials such as aluminum alloy, magnesium alloy, zinc alloy, etc. will directly affect the cost of die castings. High-performance materials are usually more expensive, but may bring higher product performance and added value.
Material utilization rate: The higher the utilization rate of materials, the less waste and the lower the cost. Optimizing design and process can improve material utilization.
2. Mold manufacturing
Mold cost: The design and manufacturing cost of molds is high, especially high-precision and complex molds. Although the initial investment is large, high-quality molds can improve production efficiency and product quality and reduce long-term costs.
Mold life: The life of the mold affects its amortization cost. Although high-quality molds are expensive, they have a long service life and a low unit cost.
3. Production efficiency
Cycle time: The cycle time of the die casting process (from injection to cooling, mold opening and removal) directly affects production efficiency. The shorter the cycle time, the higher the output per unit time, and the lower the cost per product.
Automation: A high degree of automation can reduce labor costs and improve production efficiency, but the initial investment is large. In the long run, automated equipment can significantly reduce operating costs.
4. Process parameters
Injection speed and pressure: Injection speed and pressure affect product quality and production efficiency. Optimizing process parameters can reduce defects, improve yield, and reduce rework and scrap costs.
Cooling time: Appropriate cooling time can improve production efficiency, but too short cooling time may cause product quality problems. Reasonable cooling time settings help balance efficiency and quality.
5. Post-processing process
Deburring and surface treatment: Post-processing processes such as deburring, polishing, and spraying increase production costs. High-precision die-casting processes can reduce these additional processing requirements and reduce total costs.
Heat treatment: Some die-castings require heat treatment to improve mechanical properties, which increases costs. But optimizing the process can reduce the need for heat treatment and save costs.
6. Quality control
Defect rate: Defects such as pores, cold shuts, and shrinkage holes in the die-casting process increase scrap rates and rework costs. Strict quality control and optimized processes can reduce defect rates and increase yields.
Testing and inspection: Although high-precision testing equipment and comprehensive inspection processes increase costs, they can ensure product quality and reduce returns and compensation costs caused by quality problems.
7. Scale effect
Mass production: Large-scale production can dilute fixed costs, such as mold manufacturing costs and equipment depreciation costs. The larger the production batch, the lower the unit cost.
Supply chain management: Optimizing supply chain management and raw material procurement and establishing a stable supply channel can reduce raw material costs and inventory costs.
8. Innovation and technology
Application of new technologies: The introduction of new technologies such as 3D printing and intelligent manufacturing can improve production efficiency and product quality. Although the initial investment is large, it can significantly reduce costs in the long run.
R&D investment: R&D investment in new processes and new materials may increase short-term costs, but it can bring long-term technical advantages and cost savings.
In summary, die-casting technology is closely related to cost. By optimizing process parameters, improving automation level, strict quality control and reasonable selection of materials, production costs can be effectively reduced and competitiveness can be improved.
