Torsion Springs - Avoiding Problems

Описание: One of the challenges with torsion springs is they are not very favorable in the post plating process because they have long arms typically and have some type of shape on the end.

Zinc plating parts of this size are done in very large barrels that have holes in the outside of the barrels to allow the fluid to run inside of the barrel to be able to plate the part.

So they’re charging these with plus negative and minus charges to get the zinc to stick to it; and unfortunately some of these arms can go through the holes in the barrel and can cause all sorts of problems with consistency in plating and arcing and hydrogen embrittlement.

The geometry of the part will dictate whether or not the part should be post plated.

The choice of material is important due to the shape design because, due to the application, some parts need to have rust protection finish on them.

Even if the parts are not plated, they have a propensity to tangle during the shipping process.

There are different ways that we can package these parts to make it easier for the folks in the assembly line or in an automated assembly line application to be able to pull parts apart, we can ship them in smaller quantities, and smaller bags, a special container.

It’s very important that you allow your spring maker to work with you during the design process of your assembly.

We can look at the shape of a part and make a recommendation to a design group or an engineering group as to whether or not that part should have a strong consideration to be pre-pated, perhaps made out of stainless steel, or is a solid candidate for a post plating process.
