Types of Die Casting Processes at IEC MOULD
To support a wide range of project needs, IEC Mould provides three types of die casting machines, suited for different materials and deisgn complexities. We primarily apply hot and cold chamber casting. For components with tight tolerances and strong structural requirements, we offer advanced processes like semi-solid casting.
Cold Chamber Die Casting
Cold chamber die casting melts metal in a separate furnace before casting. The molten metal is poured into a cold chamber, where a piston pushes it into the die under high pressure. The process handles high melting point metals like aluminum. The separation prevents contamination and extends die life. This type of die casting produces car engine parts, aircraft components, and electronic housings where strength and precision matter
Hot Chamber Die Casting
Hot chamber, or gooseneck casting, connects the melting furnace directly to the casting machine. A piston pulls molten metal from the furnace and injects it straight into the die. This creates faster cycle times and reduces waste since the metal stays hot throughout the process. The process suits low melting point metals like zinc, magnesium alloys. The direct connection allows efficient high-volume production of toys, hardware, decorative items, and small mechanical parts.

Die Casting Materials & Finishes
Die casting tooling is manufactured from high-grade hardened steel to reliably withstand extreme temperatures, high injection pressures, and long production cycles. This ensures tooling stability, dimensional consistency, and extended mold life throughout serial production. For die casting parts, non-ferrous metals are primarily used due to their excellent fluidity, controlled solidification behavior, and relatively low melting points, which enable the production of complex, thin-wall, and high-precision components. While ferrous metals may be applied in limited or specialized cases, they are far less common in die casting compared to aluminum-, zinc-, magnesium-, and copper-based alloys.
IEC MOULD supports a wide range of standard die casting materials and also provides customized material solutions based on specific mechanical, thermal, and application requirements.
Tool Steel H13
Premium hot-work steel with high strength, toughness, and thermal stability. Maintains hardness and dimensional integrity under repeated heat cycles, ideal for aluminum and magnesium die casting molds with long production life.
Tool Steel 8407
Superior thermal shock resistance and higher toughness than H13. Better heat dissipation improves temperature stability and extends mold life, making it ideal for heavy-duty and long-run die casting applications.
Tool Steel 2344
Excellent high-temperature strength and resistance to thermal fatigue. Easy to machine and polish, delivering fine surface quality and dimensional stability—ideal for detailed and precision die casting tooling.
Zinc Die Casting
Excellent mold flow and dimensional accuracy make zinc die casting ideal for small, detailed components with tight tolerances. It is widely used in electronics, connectors, locks, and everyday hardware, offering a strong balance of mechanical strength and cost efficiency.
Common Zinc Alloys:
ZAMAK 2 · ZAMAK 3 · ZAMAK 5
Aluminum Die Casting
Lightweight and corrosion-resistant with an excellent strength-to-weight ratio, aluminum die casting enables the production of complex, thin-wall components with high dimensional accuracy. It is widely used in automotive, aerospace, and electronic applications where weight reduction, structural performance, and thermal conductivity are critical.
Common Aluminum Alloys:
ADC10 · A380 · ADC12 · Pure Aluminum · DM6 · HA6 · HA4 · 6063
Magnesium Die Casting
High strength with excellent machinability and natural EMI shielding, magnesium die casting is ideal for lightweight electronic housings, automotive components, and handheld device enclosures.
Common Magnesium Alloys:
AZ91D · AM60B · AM50A
Copper/Brass Die Casting
Known for excellent electrical conductivity, corrosion resistance, and mechanical strength, brass and copper die casting is well suited for electrical components, fittings, connectors, and functional hardware. These alloys are commonly selected for applications requiring durability, thermal performance, and long-term reliability.
Common Alloys:
Brass alloys · Copper-based alloys
Provides a functional finish with smooth surfaces and minor tool marks, ideal for non-cosmetic applications.
Enhances corrosion and wear resistance of aluminum parts while offering durable color options for improved appearance.
Protects aluminum and zinc die castings from corrosion and prepares surfaces for painting or coating.

How We Control The Quality of Your Die Cast Parts
🔍 Material Assurance
We use only high-purity aluminum, zinc, magnesium, and copper alloys. All incoming materials undergo chemical analysis to ensure consistent quality.
⚙️ Process & Dimensional Control
Key die casting parameters—such as injection pressure, fill speed, & mold temperature—are strictly monitored. Finished parts are inspected using precision tools (e.g., CMM) to ensure dimensional accuracy.
🌧️ Corrosion & Defect Inspection
Coated parts are salt spray tested for corrosion resistance. X-ray inspections are performed on critical parts to detect internal defects like porosity or shrinkage.
🔩 Mechanical & Surface Testing
Each batch is tested for tensile strength and hardness. Surface quality is ensured through paint adhesion (cross-cut) testing and visual inspection during production.
