Hi,
Here's what I do for entering springs. I make Material Modules for each of the different materials that we make springs out of. For instance I have a module for each of the following wire types: phophated music wire, galvanized wire, Oil Tempered Chrome Silicon, 302 SS, etc.
For each of these wire modules, I use either the ASTM spec or testing performed by an outside lab, if it's been done, to enter the specific substances and amounts. Then I internally release the modules (not publish).
Then when I enter a spring (component) into the system, I insert the appropriate material module and enter the weight and other required info.
I also make material modules for any additional finish that we use such as paint, stain, chrome plating, etc and insert them when necessary.
Hope this helps.
Kim
