Aluminum Alloy Die Casting Parts
High Pressure Die Casting | ADC12 / A380 / AlSi9Cu3 / AlSi12Fe | Weight
Product Overview
Wuxi Hengzhihui Metal Materials Co., Ltd. specializes in high pressure aluminum die casting (HPDC) using advanced cold chamber die casting machines with clamping force up to 800 tons. We produce high‑precision, sound‑free aluminum castings with individual part weight ≤10 kg. Our in‑house capabilities include mold design, precision casting, CNC machining, and surface finishing – all under one roof.
Our primary alloy portfolio covers the most demanded aluminum materials for industrial and automotive applications:
ADC12 (JIS)
A380 (ASTM)
AlSi9Cu3 (DIN)
AlSi12Fe (DIN)
These alloys offer excellent castability, good mechanical properties, corrosion resistance, and thermal conductivity.
Key Technical Specifications
| Parameter | Value / Range |
|---|---|
| Die casting machine tonnage | 80T – 800T |
| Max part weight (single piece) | ≤10 kg (up to ~10.7kg with 800T) |
| Alloys available | ADC12, A380, AlSi9Cu3, AlSi12Fe (custom alloys on request) |
| Casting tolerance | IT11 – IT13 (or finer with post‑machining) |
| Surface roughness (as cast) | Ra ≤ 3.2 μm (typical) |
| Max projected area | 600 – 2500 cm² (depending on tonnage) |
Material Advantages – Why These Alloys?
ADC12
Excellent fluidity and pressure tightness
Widely used for general engineering parts, engine brackets, covers, and housings
Good machinability and recyclability
A380
Most common Al‑Si‑Cu die casting alloy
Combines high strength, good thermal conductivity, and superior corrosion resistance
Ideal for complex thin‑wall components (electronic enclosures, automotive structural parts)
AlSi9Cu3 (EN 1706)
Higher copper content for improved strength at elevated temperatures
Excellent die filling properties, suitable for highly stressed parts (transmission housings, oil pans)
AlSi12Fe
Low copper, iron‑containing alloy → reduces die soldering and extends tool life
Very good corrosion resistance and dimensional stability
Often chosen for large, thin‑walled castings (LED housings, industrial radiator frames)
Production Capabilities
Machine fleet: Multiple units from 80T to 800T (including high‑performance 800T machines with 4‑stage injection control)
Injection performance: Up to 8 m/s injection speed, pressure build‑up time
Monitoring system: VMES production visualization + Omron PLC with imported electronic rulers → fully traceable process parameters
Quality control: ZEISS CMM, optical spectrometer, X‑ray inspection, tensile testing – all in‑house
Secondary operations: CNC turning & milling (3/4/5‑axis), deburring, vibratory finishing, tumbling, powder coating, anodizing, and plating (subcontracted)
Typical Applications (with recommended alloys)
| Application | Suggested Alloy |
|---|---|
| Automotive – engine brackets, oil pans, pump housings | A380, AlSi9Cu3 |
| Automotive – transmission housings, structural parts | AlSi9Cu3, ADC12 |
| Communication – 5G base station heat sinks, RF housings | ADC12, AlSi12Fe |
| Industrial – motor housings, pneumatic valve bodies | A380, ADC12 |
| LED lighting – radiator shells, lamp holders | AlSi12Fe |
| Home appliances – washing machine brackets, compressor parts | ADC12 |
