What Is Dip Coating?

Dip coating is a fairly straightforward process where the item to be coated is heated and then dipped into liquid plastic. After the plastic sets, the coated piece is heated again to cure the plastic coating.

What Is Spin Coating?

To perform spin coating, the parts to be coated are loaded into a porous basket. The basket full of parts is dipped into the liquid plastic to coat them. Then, the filled basket is put into a device to spin it at high speeds so that the excess coating will fly off, leaving just the coated parts. Additional layers can be added as needed, and then they are then heat cured in the same fashion that dip coated parts are set.

Best Candidates for Spin Coating

Spin coating is clearly limited to the size of the basket your facility can spin, and the size of parts which can fit into that basket. It is generally a great solution for coating small parts such as fasteners and other hardware components.

Best Candidates for Dip Coating

Dip coating is an excellent solution for countless applications. Some smaller parts that would seem to be good candidates for spin coating can produce poor results with that process and do better with dip coating. These include small parts that could interlock or nest during the spinning process or those which have deep or complicated openings that would prevent an even coating.
