Aluminum Alloy Die Casting Parts
High Pressure Die Casting | ADC12 / A380 / AlSi9Cu3 / AlSi12Fe | Weight <10kg | ≤800T Locking Force
Product Overview
Wuxi Hengzhihui Metal Materials Co., Ltd. specializes in aluminum high pressure die casting (HPDC) using advanced cold chamber die casting machines with clamping force up to 800 tons. We produce high‑precision, sound‑free aluminum high pressure die 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.

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 <15 ms
-
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 |
