When to use injection molding?

When to choose injection molding?

High-volume production:

When you need to produce hundreds or thousands of identical parts, injection molding is a very efficient process. 

Complex geometries:

The process can handle intricate designs with ease, making it suitable for parts with features like ribs, bosses, and undercuts. 

Tight tolerances:

Injection molding can achieve precise dimensions, with tolerances often achievable within ±0.500 mm (0.020") and sometimes even tighter. 

Smooth surface finishes:

Injection molding is known for producing parts with smooth, consistent surface finishes, which are desirable for many applications. 

Isotropic properties:

If your application requires uniform material properties in all directions (strength, etc.), injection molding is a good choice. 

Testing in production material:

Injection molding allows you to test parts in the actual material that will be used in the final product. 

Cost reduction:

While initial tooling costs can be high, the per-unit cost of injection molded parts can be significantly lower than other methods, especially at high volumes. 

Material versatility:

Injection molding can work with a wide range of plastic materials, offering flexibility in material selection. 

Industries:

Injection molding is widely used in industries like automotive, consumer electronics, medical devices, and packaging.
