Custom Die Casting Services for Overseas B2B Buyers
For over 40 years, The Federal Group USA has served as a primary contract manufacturing partner for international procurement teams, automotive OEMs, industrial automation firms, and medical equipment builders. We engineer high-integrity die-cast components that eliminate secondary machining operations and shorten global supply chain lead times.
Utilizing high-pressure hot chamber and cold chamber die casting machines ranging from 600 to 1,200 tons of locking force, our production facilities cast complex geometries with thin wall sections, exceptional dimensional repeatability, and superior surface finish.

Die Casting Alloy Capabilities & Mechanical Properties
We work with international procurement engineers to select the exact alloy composition required for thermal management, electrical shielding, and structural strength.
| Metal Alloy | Casting Method | Key Characteristics | Typical Applications | Tolerance Standard |
|---|---|---|---|---|
| Aluminum A380 / ADC12 | Cold Chamber | High thermal conductivity, corrosion resistance, excellent fluidity for complex geometry | Engine brackets, motor housings, heat sinks, electronic enclosures | ±0.002" / 0.05 mm |
| Aluminum A360 | Cold Chamber | Superior pressure tightness, excellent corrosion resistance, high ductile strength | Hydraulic valve bodies, fluid pumps, marine hardware | ±0.0025" / 0.06 mm |
| Zinc Zamak 3 / Zamak 5 | Hot Chamber | High impact strength, superior dimensional stability, ideal for thin-wall plating | Precision gears, door hardware, electrical connectors, lock cylinders | ±0.001" / 0.025 mm |
| Magnesium AZ91D | Cold / Hot Chamber | Ultra-lightweight (33% lighter than aluminum), high EMI/RFI shielding, vibration damping | Automotive steering columns, power tool housings, medical portable frames | ±0.003" / 0.075 mm |
Advanced Die Casting Technologies
Cold Chamber Die Casting
Designed for high melting point metals such as aluminum and copper alloys. Molten metal is ladled into a cold chamber shot sleeve before being injected into the steel mold under pressures reaching 10,000 to 15,000 PSI.
- Ideal for large structural components up to 50 lbs
- Minimal thermal shock on injection components
- Exceptional dimensional retention across 100,000+ shot die lives
Hot Chamber Die Casting
Utilized for lower melting point metals such as zinc and magnesium. The injection mechanism is submerged directly in the molten metal bath, enabling ultra-fast cycle times and extremely thin wall section capability down to 0.75 mm.
- High production speeds up to 15-30 shots per minute
- Smooth cast surface finish (Ra 1.6 to 3.2 µm)
- Reduced scrap rates through automated metal feeding

Frequently Asked Questions by Overseas Buyers
Clear answers to key purchasing, tooling, lead time, and logistical questions.
What is the typical tooling lead time and life expectancy for die casting molds?
Standard hardened H13 steel die casting tooling takes approximately 4 to 6 weeks for design, flow simulation, T1 sample casting, and initial inspection. Mold life spans range from 100,000 shots for aluminum up to 500,000+ shots for zinc alloys depending on maintenance schedules.
What surface finishes are available for exported die cast components?
We provide full surface finishing including shot blasting, vibratory deburring, anodizing (Type II & III), powder coating, wet painting, electro-less nickel plating, chromate conversion, and e-coating tailored for severe atmospheric corrosion protection.
How does TFG USA handle international shipping and customs logistics?
TFG USA manages complete door-to-door or port-to-port supply chains including export vapor-corrosion-inhibitor (VCI) packaging, sea/air freight forwarding, customs clearance documentation, and localized warehousing management.
