Molds for metal products are heavy-duty, highly durable containers used to shape hot, liquid metal into specific, solid parts.
Here is the simple breakdown of what they do:
• The "Ice Tray" Idea: They work like filling an ice tray. You pour melted (liquid) metal into the mold's cavity.
• Cools Down: The metal cools rapidly inside the mold and solidifies into the desired shape.
• The Process (Casting):
o Die Casting: A common method where liquid metal is forcefully injected into a permanent metal mold under high pressure. This is fast and precise.
o Sand Casting: A temporary mold made of compressed sand is used for larger, rougher parts.
• Mass Production: These molds are built incredibly tough so they can be reused thousands of times to mass-produce metal items quickly and efficiently.
In short, a metal mold is a robust, heat-resistant template that shapes hot liquid metal into its final, solid form during manufacturing.
