Die casting and injection molding are distinct manufacturing processes, though they share some similarities. Here's a concise comparison:

Die Casting:

Material: Uses molten metals (e.g., aluminum, zinc, magnesium).

Process: Molten metal is forced into a mold cavity under high pressure, cools, and solidifies to form the part.

Molds: Made of durable steel to withstand high temperatures and pressures.

Applications: Produces strong, precise metal parts like automotive components, hardware, or electronics housings.

Characteristics: High strength, good surface finish, suitable for high-volume production of metal parts.

Injection Molding:

Material: Uses thermoplastics, thermosetting plastics, or sometimes elastomers.

Process: Molten plastic is injected into a mold, cooled, and solidified to form the part.

Molds: Typically made of steel or aluminum, designed for lower temperatures than die casting.

Applications: Produces plastic parts like packaging, consumer goods, or medical devices.

Characteristics: Versatile for complex shapes, cost-effective for high-volume plastic parts.

Key Differences:

Material: Die casting uses metals; injection molding uses plastics.

Temperature and Pressure: Die casting involves higher temperatures and pressures due to metal's properties.

Applications: Die casting is for metal parts; injection molding is primarily for plastic parts.
