Die Casting Capabilities
Die casting is a metal casting process that forces molten metal under high pressure (1,500-30,000 PSI) into steel mold cavities (dies). The dies are precisely machined to produce complex shapes with excellent dimensional accuracy and surface finish. There are two main methods: hot chamber die casting (for zinc, magnesium, and low-melting-point alloys) and cold chamber die casting (for aluminum, brass, and higher-melting-point alloys). Die casting produces parts with thin walls, complex geometries, and fine surface detail at production rates of hundreds per hour. It is one of the most cost-effective processes for high-volume production of metal parts.
±0.002"-±0.005" depending on size; ±0.001" for critical features with secondary machining
8-16 weeks for tooling; 2-4 weeks for production
$10,000-$200,000+ for tooling; $0.50-$20 per part in production

Die Casting in Saint Louis — FAQ
How many Die Casting providers are in Saint Louis, MO?
The St. Louis metropolitan area has approximately 1,800 manufacturing establishments, many of which offer die casting services. The area employs about 42,000 manufacturing workers, ensuring a skilled workforce for your project.
What metals can be die cast?
The most commonly die cast metals are aluminum alloys (65% of market), zinc alloys (30%), and magnesium alloys (5%). Aluminum die castings offer the best combination of light weight, strength, and corrosion resistance. Zinc provides excellent detail and lower tooling costs.
How many parts can a die casting die produce?
Die life depends on the metal being cast. Zinc dies can last 1,000,000+ shots. Aluminum dies typically last 100,000-300,000 shots. Brass and copper dies may last only 10,000-50,000 shots due to higher casting temperatures.
What is the minimum volume for die casting?
Due to high tooling costs ($10,000-$200,000+), die casting is typically economical at volumes above 5,000-10,000 parts. For lower volumes, sand casting, investment casting, or CNC machining may be more cost-effective.
Can die castings be welded?
Standard die castings are difficult to weld due to porosity from trapped gases. Vacuum die casting and squeeze casting produce denser parts that can be welded. For weldable applications, these specialized processes or alternative casting methods should be considered.
