What is Machining?

Machining is a subtractive manufacturing process that involves cutting, drilling, milling, or grinding materials to achieve desired shapes and sizes. This technique is predominantly applied to metals, plastics, and composites and is essential for creating precise components.

Key Machining Processes

• Turning: The material is rotated against a cutting tool, ideal for cylindrical parts.
• Milling: A rotating cutter removes material while the workpiece is held stationary.
• Drilling: Creates holes in materials, forming a crucial step in assemblies.
• Grinding: Refines surfaces to achieve high precision and smooth finishes.

Injection Molding Applications

Injection molding, a favorite in high-volume production, involves injecting molten material—usually plastic—into a mold where it cools and solidifies into the final shape. This process is highly efficient for producing complex geometries and is widely used in various industries.

Advantages of Injection Molding

• High Speed: Quick production cycle times save time and costs.
• Consistency: Produces repeatable and uniform products, reducing waste.
• Material Versatility: Can use a wide range of materials, from thermoplastics to metal.
• Complex Shapes: Capable of creating intricate designs that other methods may not achieve.
