Advantages of Die Casting

 

Complex Geometry

Die casting can reliably produce custom die cast parts with thin walls and challenging geometry that is durable and dimensionally stable.

 

Strength

Metal die castings are typically stronger than plastic injection molded parts and more resistant to high temperatures. Metals such as aluminum offer exceptional strength-to-weight ratios.

 

Precision

Die casting offers typical tolerances ranging from +/-0.003″ – 0.005″ per inch but can go as tight as +/- .001” depending on your specifications, part geometry, and material.

 

Custom Finishes

Metal finishers can produce cast parts with smooth or textured surfaces, paints, and plating finishes. Finishes can protect from corrosion and improve cosmetic appearance.

 

Disadvantages of Die Casting

 

Tooling Cost

While the per piece cost of die cast parts is relatively low, the tooling dies and maintenance costs can require a high initial investment.

 

Not for Low Quantities

Due to the higher upfront tooling costs, die casting is not economical for low-volume runs. We recommend only considering die casting for quantities greater than 1000.

 

Lead Times

Before production, many steps must be accomplished first, often taking multiple weeks to execute. These steps include addressing DFM concerns, tool design, manufacturing the tools, and creating samples. The upfront checks and validations make die casting one of the slower manufacturing processes to ramp up compared to others.
