Pin Line + Dip & Spin Coating
Two production methods for high-volume work: Pin Line (hook, coat, bake) and Dip & Spin (submerge, spin, bake).
Production coating built for throughput and repeat runs
If you coat parts in volume, the method matters. Pin line and dip & spin are built to deliver repeatable handling, consistent coverage, and high throughput across scheduled production runs.
Pin line vs. dip & spin
Pin Line = best for parts that can be hung
- Use when parts have hang points and you want controlled coating and bake cycles for repeat production.
Dip & Spin = best for bulk small parts
- Use when parts are too small to hang efficiently (fasteners, small hardware, small components) and you need volume processing.
Pin line coating (Hook, Coat, Bake)
What it is: Parts are hung, then coated, then baked/cured—built for high-volume repeat runs.
Best for: Manufactured parts that can be fixtured/hung and need consistent finish across batches.
Options:
- Optional zinc-phosphate pretreatment prior to coating when required for adhesion and corrosion performance. Zinc phosphate pretreatments are widely used in coating systems and have been shown to improve corrosion protection and wet adhesion in coating/substrate interfaces.
- Pairs well with fluoropolymer systems (example: PTFE/Teflon) when your parts and bake limits match the cure requirements. Teflon™ PTFE coatings are specified with defined cure temperatures (often 725–750°F depending on product).
Dip & spin coating (Submerge, Spin, Bake)
What it is: Parts are loaded in bulk, submerged, then spun to remove excess coating and control film build, then baked/cured.
Best for: Small parts at scale where hanging is inefficient (fasteners, clips, small brackets, small machined components).
Coverage control: Spin step is used to reduce pooling and help uniformity on high-quantity small parts.
