Aluminum Alloy Die Casting

Aluminum alloy die casting is a process that involves injecting molten aluminum alloy at high pressure and speed into a precision mold for one-time molding. It offers advantages in efficiency, complexity, consistency, and lightweight design, providing end-to-end services from design to surface treatment. It is an ideal choice for product structure integration and cost control.

Product Introduction

Aluminum Alloy Die Casting

Core Definition

Core Features and Process Advantages

Complex Molding: Capable of integrating multiple structures, with uniform thin walls of 1.2–2.0 mm (local areas of communication components can be 0.8 mm), and precise surface details.

Stable Performance: ADC12, A380, and other alloys undergo T5/T6/T7 heat treatment to improve mechanical properties, achieving dimensional tolerances of CT6–CT7.

Comprehensive Post-processing: Includes CNC precision machining and various surface treatments, with comprehensive testing equipment to ensure quality.

Main Applications

Automotive: Engine cylinder head covers, motor housings, etc.

Communication Electronics: 5G filters, optical module housings, etc.

Industrial Equipment: Tool housings, pump and valve housings, etc.

New Energy: Electronic control boxes, battery pack structural components, etc.

Smart Home and Medical: Smart door lock housings, medical equipment brackets, etc.

Frequently Asked Questions

Q1: Why choose aluminum alloy die casting instead of plastic, sheet metal, or machining?

A: Die casting is superior to plastic for high-strength and high-thermal-conductivity requirements; superior to sheet metal for complex parts requiring high integration; and for large-volume, complex parts, die casting is often more cost-effective and efficient.

Q2: What precision can aluminum alloy die castings achieve, and what factors influence it?

A: Typically CT6, and can reach ±0.05 mm after precision machining. Influencing factors include mold quality and process stability, which are optimized and controlled through CAE simulation.

Q3: What are the common defects in die casting, and how are they controlled?

A: Common defects include pores and shrinkage cavities. These are prevented through CAE optimization, high-vacuum die casting, and controlled through first-piece inspection and X-ray sampling.

Q4: What is the cycle time from design to mass production for a new project?

A: The process typically takes 12–16 weeks, including design and DFM analysis (2–3 weeks), mold development (6–8 weeks), sample validation (2–3 weeks), and small-batch trial production (2–3 weeks).

Q5: Is die casting economical for tens of thousands of units per year?

A: Generally, yes. Although mold investment is high, the high production efficiency and low unit cost often result in lower overall cost compared to other processes after amortization. A cost analysis can be provided.
