Die Casting Capabilities
Tolerance
High-precision die casted parts need secondary machining to meet tolerance requirements, achieving accuracy up to ±0.01mm
Minimum Wall Thickness
Aluminum alloy recommended 1.5mm, zinc alloy can go down to 0.8mm
Wall Thickness Ratio
Keep within 1:3 ratio to avoid uneven filling
Hole Diameter
Due to high temperatures during aluminum die casting mold processing, round holes smaller than 3mm diameter require secondary drilling. Product threaded holes and external threads are formed through secondary machining.
Draft Angle
Minimum 0.5° to avoid demolding difficulties Maximum Die Life (Number of Cycles) Zinc: 1,000,000 Magnesium, Aluminum: 100,000
Lead Time
20-25 days. Specific timing varies based on mold type and product structure complexity
Die Casting Materials
Die cast tooling uses hardened steel for withstand high temperatures and pressure. For die castings, non-ferrous metals are preferred for their fluidity and low melting points. Ferrous metals are used in some cases but less commonly.
Hardened Tool Steel
- Steel H13: Strong at high heat. Tough and crack-resistant. Stays hard when hot. Good for aluminum and magnesium casting.
- Steel 8407: Handles heat changes well. Tougher than H13 steel. Conducts heat better and lasts longer. Good for heavy-duty casting work.
- Steel 2344: Strong at high heat. Resists cracking from heat cycles. Easy to machine and polish. European steel grade for detailed parts.
Die Casting Alloys
- Aluminum Die Casting: ADC10, A380, ADC12, Pure Aluminum, DM6, HA6, HA4, 6063
- Magnesium Die Casting: AZ91D, AM60B, AM50A
- Zinc Die Casting: ZAMAK2, ZAMAK3, ZAMAK5
