Dip Spin vs Hot Dip Galvanizing
Compared to hot dip galvanizing methods, dip spin coating offers several performance advantages, particularly for fasteners and small components that require uniform coverage and dimensional accuracy.
Here’s a breakdown of how they differ:
| Feature | Dip Spin Coating | Hot Dip Galvanizing |
|---|---|---|
| Process | Dip + spin for even application | Submersion in molten zinc |
| Torque Control | Excellent, maintains performance specs | Poor, often impacts thread usability |
| Thread Coverage | Thin, uniform, dimensionally stable | Thick layers that may affect fit |
| Cost Efficiency | Highly efficient for bulk processing | Less efficient for large-scale runs |
| Environmental Impact | PFAS-free, RoHS compliant, energy saving | Higher energy use and material consumption |
Why Dip Spin Wins
Unlike electroplating or hot dip galvanizing, dip spin coating eliminates the risk of hydrogen embrittlement and offers better torque-tension consistency. Its lightweight, thinner coatings preserve part geometry while providing robust corrosion protection, making it ideal for high-performance components in demanding environments.

Dip Spin Coating Applications & Environmental Compliance
Dip spin coating is trusted across a wide range of industries thanks to its versatility and consistent performance in harsh environments. Common applications include:
- Automotive fasteners such as brake components and underbody bolts
- Industrial springs and washers
- Clips, rivets, and retainers
- Parts subjected to highly corrosive environments
OEMs prefer this method for its zero-drip application, which ensures uniform coverage and accurate torque specs. Its excellent repeatability also supports high-volume production without sacrificing quality.
SWD is committed to sustainable practices. Our coatings are free from PFAS and fully REACH and RoHS compliant, making them safe for use in consumer electronics, electric vehicles, and projects requiring green building certifications. Our curing systems minimize VOC emissions, supporting ISO 14001 compliance for environmental management.
We maintain quality through certifications, including:
- ISO 9001:2015
- ISO 14001:2015
- ISO 17025:2017
With an on-site A2LA-accredited laboratory, we validate every coating for performance, safety, and regulatory alignment.
