What Are Dip-Spin Coatings | The DECC Company

What is Dip-Spin Coating?

Dip-spin is a bulk application coating process. Parts are placed into baskets and immersed in a coating. The basket is then raised from the vat and spun at a high RPM, which removes any excess coating with centrifugal force. The parts are then cured, and the process is repeated as needed, depending on the coating recipe or thickness requirements.

Benefits of Dip-Spin Coatings

Cost

Economical choice for small to mid-sized parts.

Consistent Coverage

Parts can be sent through the process multiple times to reach desired thickness and coverage.

Bulk Coating

Numerous parts can be coated simultaniasly.

Sustainability

Excess coating is collected and stored.

Coating Process

DECC’s process for dip-spin application starts with in-house surface preparation, where we can either pre-bake the parts, then surface blast, or just run through our zinc phosphate wash. After the surface has been prepped, they are put into wire baskets and run through the dip-spin coating machine. Once the parts have been coated, they are then placed into a curing oven to set the coating. The parts are then sent to packing, where they are packed up and ready to be shipped.

Common solutions for dip-spin coating are zinc flake and PTFE; however, there is a wide range of solutions for which this coating application can be used.

When To Use Dip Spin

Dip-spin is ideal for a vast majority of small to mid-sized fasteners or hardware and for numerous metal stamping geometries. For larger parts, the ideal coating application is rack spray, allowing parts to be coated more effectively and at a lower cost.
