Component Molding and Over-molding - Handling Resin Inventory

#1
The company I work for does a lot of plastic component molding and overmold of custom cables and connectors for various applications. Current practice is to have the weight of the resin on the bills of materials, and when a work order is completed, the resin that was used on the work order issued to that particular job. This is a very manual process with a lot of inventory transactions for each work order and there has to be a better way. For those of you that injection mold plastics, how is it that resin inventory is managed? How do you account for setup resin, scrap, etc?

You can base it on finished production. Your system should be able to remove material as the final products are entered into inventory. You can then adjust the actual inventory every so often.

It is a labor intensive process, unfortunately it's the only process. You can estimate your material and scrap, but what happens if it's incorrect? Currently we try to minimize this process by doing it the first time, and basing the following runs off our results. (plus a few extra lbs)
Hope this helps...
