Part Numbering System Modifications HELP ???
(OP)
We are a Valve Manufacturing company, we make small motor/ pressure relief/control valves, level indicators, and chemical injection pumps. In the last 5 years, we acquired 2 other companies with same line of products. The new acquisitions introduce new parts with their existing Part Identification Numbers (PIN). That means we are having 3 different PIN System within 1 manufacturing plant. There are about 10,000 parts so it gets very confused to learn from different part numbering system.
We are trying to update to a new PIN system, the most difficult task is that what is the right way to do it. I would like to ask if anyone ever experience such tasks and wants to help us. Thank you so much for reading this post.

Part Numbers are always a contentious issue.

If your project is to incorporate the aquired companies parts into the parent companies scheme, then it is a matter of just slogging through them one by one. The cross referencing becomes vital at that point. If you find a part that is a form, fit, function match to one of your existing parts, give it the same number.
Regards and good luck,

mcorker: Thank you, your recommended article is an excellent source.
PSE: Thank you for covering the part number philosophy and its legacy. Please advise me more about bar code, how much money and time to create that.
I think this is an extremely important subject, I look forward to further discuss with any other details. Thank you.

Don't you have some form of an EPR or MRP system that will manage this point for you?

As far as which characters not to use, it depends. Generally you should avoid letters that look like numbers, but if there is a situation where one of those letters is meaningful and obvious, then go ahead.
As far as your original question, I agree with PSE. Regardless of how you set up your new part number logic, the cross-reference sheet is extremely vital. Some of the newer systems (we're implementing Oracle now) have forms for this sort of thing, and can even automatically convert from one part number to another (i.e. customer still orders part number A, even though you've changed it to part number B).
Good luck!

If you are using laser printers or thermal label printers you shouldn't have confusion between "S" and "5".
An additonal note is that the MRP system should also allow you to associate Part Numbers and Vendor Part Numbers to items you sell or buy.

Cross references with new part number and old part numbers will have to be maintained for service parts.
Update your designs based on the dollar volume for the different assemblies. Simplify and combine the designs if possible and fix any parts which present special problems to make or buy.
Good Luck

MadMango, what is EPR, MRP?
BML: Oracle is too expensive for us, we are currently using a very old database that needs to improve.
mCorker: Do I use to use ASME Y14.5?
Thank you again everyone.

If you can get a where used from the old company it will help in finding where replaced part numbers need to be worked on.
I've never worked in a company which has different part numbers for the same part because of different categories.
RE: Part Numbering System Modifications HELP ???
You will likely have some components used across various end product assemblies or sub-assemblies, for those I would recommend using one base family part number. For example:
"Intelligent" # (base #)-(material code)-(dia)-(thickness)
"non intelligent" (base #)- (addendum #)
Your sub assemblies comprise a set of parts commonly built together and used in a higher level or final assembly. Drawings here should have an associated parts list or "Bill of Materials" An intelligent numbering system might use part of the final assembly number within part numbers of unique components or sub-assemblies, non-intelligent would be just some base # and possibly an addendum #
It does not sound like your place of employment has invested in an ERP (Enterprise Requirements/Resource Planning) or MRP (Materials Requirements/Resource Planning) software. As such there may be no current limit to your part number characters. I would recommend using no more than 15 should you get an ERP or MRP system in the future.
