Aluminum alloys are the most widely used materials for die cast parts because of their strong strength weight ratio, excellent corrosion resistance, and reliable mechanical properties. Due to aluminum’s higher melting point, the cold chamber die casting process is typically required to maintain casting quality and control temperature.
Engineers choose aluminum die casting for structural components requiring dimensional stability, good surface finish, and thermal performance. Cast aluminum provides:
- High operating temperature resistance
- Strong stiffness and durability
- Excellent thermal and electrical conductivity
- Reliable corrosion and wear resistance
We offer industry-standard aluminum alloys, including A360.0, A380.0, A383.0 (ADC12), and A413.0, selected based on application, performance requirements, and post-processing needs such as CNC machining.
Zinc alloys are ideal for die cast parts requiring fine detail, thin wall thickness, and high dimensional accuracy. The hot chamber die casting process is typically used due to zinc’s low melting point, allowing fast production cycles and excellent surface finish.
Zinc die castings offer:
- High hardness and wear resistance
- Good corrosion resistance
- Tight tolerances and repeatable quality
- Excellent fluidity for complex shapes
Common alloys include Zamak 2, Zamak 3, and Zamak 5, selected for performance and post-processing capabilities
Magnesium alloys provide one of the best strength weight ratios among metals, making them ideal for lightweight die cast components. Cold chamber die casting is used to handle magnesium’s higher melting point and control solidification.
Magnesium die cast parts feature:
- High stiffness with low weight
- Vibration damping and durability
- Good thermal and dimensional stability
- Excellent machinability for precision components
Typical alloys include AZ91D and AM60, optimized for automotive, aerospace, and electronics applications.
Brass alloys are used for die cast parts requiring high electrical and thermal conductivity, corrosion resistance, and long-term durability. Brass die casting supports precision components for industrial and electrical applications.
Brass die castings provide:
- Excellent conductivity for electrical components

Die casting offers distinct advantages over traditional casting methods like sand or investment casting. By injecting molten metal into precision dies under high pressure, it produces parts that are accurate and highly repeatable.
- Tighter Tolerances: Parts consistently meet precise dimensions, reducing the need for secondary machining.
- High Efficiency: Rapid cycle times support both low-volume prototypes and high-volume production, improving overall supply chain efficiency.
- Material Savings: Minimal waste and the ability to recycle non-ferrous metals make it a cost-effective solution.
- Strength and Durability: Dense, low-porosity die cast components deliver superior mechanical properties and corrosion resistance compared to sand-cast parts.
- Complex Geometries: Intricate shapes, thin wall sections, and integrated assemblies are achievable with multi-cavity molds.
- Superior Surface Finish: Smooth surfaces reduce post-processing and allow coatings

Types of Die Castings for Your Project
High pressure die casting injects molten metal into a steel die at high speed and pressure. It produces complex parts with excellent dimensional accuracy, tight tolerances, and smooth surface finish. Ideal for high-volume production, it is widely used for aluminum, zinc, and magnesium components.
Typical products:
- Engine housings
- Transmission cases
- Gearboxes
- Automotive brackets
- Electrical enclosures
Cold chamber die casting is used for metals with higher melting points like aluminum and magnesium. Molten metal is ladled into the chamber before injection, reducing die wear and oxidation. This method ensures precision, high structural integrity, and consistent mechanical properties in medium to high volume production.
Typical products:
- Automotive engine parts
- Aerospace structural components
- Pump housings
- Industrial machinery parts
- Drone frames
Hot chamber die casting uses a plunger and gooseneck system submerged in molten metal, typically zinc or low melting alloys. It enables rapid cycle times, high fluidity, and detailed, thin-walled components. This process is efficient for high-volume production with excellent surface finish and repeatable dimensional accuracy.
Typical products:
- Hardware fittings
- Electrical connectors
- Decorative components
- Small automotive parts
- Consumer electronics housings
Low pressure die casting forces molten metal into a mold under controlled low pressure, reducing turbulence and porosity. It produces structurally sound parts with high density, tight tolerances, and minimal defects. Ideal for applications where pressure-tight, durable components are critical, including automotive and aerospace metal parts.
Typical products:
- Cylinder heads
- Valve bodies
- Pump housings
- Aerospace structural parts
- Pressure-tight industrial components
Is Die Casting Right For Your Project?
Die casting is ideal when your parts require:

- Economical, cost effective manufacturing
Die Casting for Rapid Prototyping
With our die casting services, you can get rapid prototype parts in as little as 5–7 days. Your parts will have dimensional accuracy within ±0.1 mm and tight tolerances, closely matching final production components. This lets you test fit, function, and mechanical performance before committing to full-scale manufacturing.
Die Casting Design Guidelines
Uniform Wall Thickness
Maintain consistent walls (1.5mm–3mm for aluminum) to ensure even cooling and prevent shrinkage.
Draft Angles
Apply a 1°–2° taper to cavity walls to allow the ejector pins to release the part without sticking.
Fillets and Radii
Use rounded corners to improve molten metal flow and reduce stress on the tool steel.
Rib Optimization
Use ribs instead of thick walls to increase stiffness while maintaining a high strength-to-weight ratio.
Ejector Pin Placement
Position pins on non-functional surfaces to avoid visible marks on the final surface finish.
Metal Flow Path
Design geometry to avoid "dead ends" that trap air and cause porosity or leak issues.
Minimize Undercuts
Avoid complex internal features to reduce tooling costs and simplify the production process.
Tolerance Management
Design for standard tolerances to remain cost-effective, reserving tight limits for critical precision areas.
Cored-Out Bosses
Core out mounting bosses to maintain uniform wall thickness and prevent internal voids.
Machining Stock
Add 0.5mm–1.0mm of extra metal to surfaces requiring CNC machining for final accuracy.
