Best for: Long screws (e.g., over 150mm), large-diameter screws, or high-precision requirements.
Advantages:
Screws are fixed in place, ensuring more uniform coating, especially for long parts.
Minimizes surface damage or deformation due to collisions.
Suitable for thicker coatings (e.g., high-corrosion-resistance applications).
Disadvantages:
Lower production efficiency and higher cost (manual loading required).
Very long screws (high length-to-diameter ratio) may bend slightly due to uneven suspension forces.
Best for: Short screws or high-volume production, but risky for long screws.
Advantages:
Lower cost, suitable for mass production of small parts.
Disadvantages:
Long screws may collide in the barrel, leading to uneven coating, thread damage, or bending.
Typically produces thinner coatings with inferior corrosion resistance compared to rack plating.
Conclusion:
For long screws (especially those with a high length-to-diameter ratio), rack plating is preferred to ensure quality and minimize deformation. If the screws are short (e.g., under 50mm) and cost-sensitive, barrel plating can be considered, but deformation and coating uniformity must be strictly tested.
