Painting Fish Hooks

Ask an Expert From: Products Finishing, ,

Posted on: 5/1/2011

What can you suggest in terms of applying a thicker coating to mass produce hooks that won’t bind together and thereby produce contact points?

Q. We are a fish hook manufacturer. We use the dip and spin method for coating some on some products and we would like to increase our film thickness without producing “contact points” (pools of paint where two hooks cross). Besides that challenge, we also have situations where hooks will bind together and become one huge tangled mass. We paint thousands of hooks at one time and this is a must in order to keep costs down. 

What can you suggest in terms of applying a thicker coating to mass produce hooks that won’t bind together and thereby produce contact points? Is there painting equipment other than dip/spin that will do what we need? To maintain our position in the industry, it is important that we have a smooth finish. W.V.

 
 
A.  I can tell you how to increase your film thickness, but not how to eliminate contact points entirely. You can increase your film thickness by increasing the percent of non-volatile solids in the coating material. As for your other problem, I don’t know of any other mass coating system for your hooks that will completely eliminate contact points.
Spreading the hooks on a mesh belt and passing them through a curtain coater would eliminate the huge mass hooks problem. Hopefully, the hooks would not become tangled or hooked into the mesh of the belt. However, it would possibly only minimize but not eliminate contact points. This method would also increase manual labor.
