Dip & Spin Coating
Submerge, spin, and bake — a proven bulk coating process for high-volume small parts where hanging each piece individually isn’t practical.
What Is Dip & Spin?
Dip and spin is a bulk coating process designed for small parts at scale. Parts are loaded into a perforated basket, submerged into a coating bath, then spun at controlled speed to remove excess material and promote uniform film build. After spinning, the basket goes straight into a curing oven.
It’s one of the most efficient ways to coat large quantities of small components — fasteners, clips, brackets, hardware — that would be impractical to hang individually on a pin line. The spin step is critical: it controls film thickness, reduces pooling in recesses, and helps achieve consistent coverage across the entire batch.
The Process
Submerge, Spin, Bake
A three-stage workflow optimized for throughput on small-part production runs.
01
Submerge
02
Spin
The basket is lifted and spun at a controlled RPM. Centrifugal force removes excess coating, controls film build, and reduces pooling in recessed areas.
03
Bake & Cure
The coated parts go directly into a curing oven at the temperature and duration specified for the coating system. Once cured, parts are cooled and ready for packaging.
Why Dip & Spin
Key Advantages
High Throughput
Process hundreds or thousands of parts per batch — far faster than hanging each piece individually.
Controlled Film Build
Coating Versatility
Compatible with a range of coating types — dip and spin works with various liquid coatings matched to your performance needs.
Ideal Applications
Best For Small Parts at Scale
Fasteners & Bolts
Clips & Retainers
Small Brackets
Machined Components

Multiple Dip Spin Machines In-House
Sandmans operates several dip spin machines, giving us the capacity to handle concurrent runs across different coating types and part sizes. Whether it’s a short custom batch or a recurring production schedule, we can accommodate your volume without bottlenecking other work.
Parts Large Enough to Hang?
If your parts have fixture points and you need controlled coating placement with masking, our Pin Line process is designed for that — hook, coat, and bake with individual part handling and optional zinc-phosphate pretreatment.
