Level of surface finish achieved: 0.40 – 0.10 micro meters

Advantages:

–      Good surface finish

–      Complex geometry can be produced.

–      High production rate

–      Fully automated,  so less manpower required.

Disadvantages:

–      High tooling and equipment cost

–      Part with large undercut cannot be produced.

Ideal applications: Suitable for making large scale production of the plastic and similar components.
