Die-castings are precision parts manufactured through die-casting technology. The process involves injecting molten metals (copper, zinc, aluminum, or alloys) into a die-casting machine under high pressure (30-150MPa, up to 200MPa for complex parts). The metal fills the mold cavity, cools, and solidifies to produce parts matching the mold's specifications. Also known as die-cast parts, pressure castings, or die-cast metal components.

• Complex Shape Capability: Excellent metal fluidity (aluminum: 30-80mm/s, zinc: 50-100mm/s) allows production of intricate designs including 0.5mm thin walls, <1mm micro-holes, and multi-chamber structures. Enables consolidation of 5-8 parts into single components.
• High Precision: Achieves IT11-IT13 tolerances (IT8-IT10 for precision parts) with 1.6-6.3μm surface roughness. Reduces machining by 30-50% and saves over 40% in processing costs.
• Material Efficiency: 0.5-2mm casting allowance improves material utilization by 20-30% versus traditional casting. Lowers electricity use by 50% and labor costs by 30%.

• Automotive: 50-100 die-cast parts per vehicle (8-15% of total weight) including engine blocks, transmission housings, and structural components. Enables 100kg weight reduction = 0.3-0.6L/100km fuel savings.
• Electronics: Housings, brackets, and heat sinks for devices with 30-50dB EMI shielding. 1-2mm aluminum housings offer 2-3x impact resistance versus plastic.
• Aerospace: Magnesium alloys reduce spacecraft weight by 1kg = $10,000-$20,000 launch cost savings.
• Medical: Surgical instruments with ≤0.05mm tolerances and 500+ hour corrosion resistance.
• Other: Motorcycles, power equipment, architectural decor with 50kg+ load capacity.

Selecting the optimal die-casting material requires balancing process requirements with application demands. Key options include:

• 46100 / ADC12 / A383 / Al-Si11Cu3
• 46500 / A380 / Al-Si8Cu3

AZ91D, AM60B, AS41B - High strength-to-weight ratio with excellent corrosion resistance.

Superior thermal/electrical conductivity for rapid heating/cooling applications. Ideal for EMI shielding components.
