Mold machining and CNC (Computer Numerical Control) machining, although belonging to the machining field, have clear differences in several aspects. Here are the main differences:

1. Different Workpieces:

• Mold Machining: A mold is a tool used to produce parts. In large-scale production, molds can give us almost identical parts, such as injection molds and die casting molds.

• CNC Machining: CNC machines are more universal and can machine a variety of parts, from complex engine components to unique art pieces.

2. Different Machining Methods:

• Mold Machining: In mold machining, the material is filled or injected into a pre-manufactured mold, then cooled or hardened, forming the desired part shape.

• CNC Machining: In CNC machining, the part is created by cutting or engraving from a block of material. CNC machines usually have several rotating cutting tools that can operate dynamically on multiple axes.

3. Differences in Production Quantity:

• Mold Machining: Molds are often used for mass production as they come at a high cost but allow for quick part formation, making them suitable for large-scale production.

• CNC Machining: CNC machining is typically used for custom parts, low-volume production, or prototype manufacturing as it can quickly adapt to new designs and modifications.

4. Cost and Time Differences:

• Mold Machining: The cost and time for mold manufacturing are usually higher than CNC machining, with more cost and time requiring dedication to the design and manufacturing process of the mold. However, once the mold is established, it allows for mass production of parts and costs are distributed as production increases, reducing the cost per unit.

• CNC Machining: For the production of small quantities or single pieces, CNC machining can be faster and cheaper. It allows for rapid prototyping and design iterations.
