Time standards for fastener assembly?
Time standards for fastener assembly?
(OP)
Hi,
I'm a manufacturing engineer at a small company looking to bring a few products from R&D to production. I am doing some cost estimates and was wondering if there are standards for how long it takes a worker to assemble various types of fasteners (based on size and length etc.)
Thanks for any help in advance.

"Wildfires are dangerous, hard to control, and economically catastrophic."
"Fixed in the next release" should replace "Product First" as the PTC slogan.

You may need MTM (method time measurement) knowledge to come out with process time.

If you are using any kind of auto feed tools the manufacturer may have some data to get you started. Come to think of it, they probably have some for manually assembled fasteners for comparison.

What you may have to do is to conduct - say 10 - observations.
First is to make a list of each successive task and the estimated time that it takes. You can use excel to do that.
Then you observe a well trained employee (with their supervisor preferrably) and make sure that all the tasks that are carried out are listed and happening in the right order (usually it differs from one worker to another even if it shouldn't!), record the time it takes. Repeat 10 times, and you have your standards.
It is a common approach in the industry.
You won't find a set standard for the industry, because there are too many variables that come into play for each company - these known as causes of lost time, such as ergonomics and material flow.

Coming to think twice about it, since you don't produce them yet (misread your message...). Griffy is right, the best approach is probably the manufacturer ; be cautious however! Manufacturers have a tendancy to exaggerate their time studies to make a better sell...
