Several points should be taken into consideration when deciding to move injection molds from one supplier to another. The ideal solution is one in which the existing supplier, new supplier and customer are able to openly communicate while maintaining all customer deliverables in the process. However, when this is not possible, having a supplier that has experience with this type of transaction is extremely invaluable. There is no substitute for experience and comprehensive planning.
The following Mold Transfer Guidelines provide key points to consider when transferring molds:
This will cover the time necessary for the new supplier to put the essential provisions in place to transact future business uninterrupted. If the buffer is too small, it will put undue pressure on all parties, requiring alternative plans without sufficient time to execute.
Ample time should be given to:
Current Supplier/Customer
New Supplier
Both the new supplier and the customer should be on the same page as to what the expected deliverables are. This will establish the basic foundation from which the future relationship will be measured.
Key contacts should be made in the areas of Quality, Engineering, Manufacturing, Purchasing and Customer Service. This will streamline communications and insure the proper parties are aware of key deliverables.
It's best to create boundary samples to avoid interpretation errors later on. The goal is to eliminate subjectivity as much as possible on both sides (supplier and customer).
If possible, retain the last "acceptable" shot (part and runner attached if applicable) off of each mold prior to transferring. This visual sample will provide key information to the new supplier in terms of current mold condition and customer acceptance standards. Preferably, parts should be untouched as they are molded prior to any secondary operations. This last shot should be inspected by the new supplier and matched against the customer's current quality acceptance standards for conformance (i.e. all notes, dimensions and cosmetic attributes). Noted deviations will require customer disposition to assure all acceptance documentation matches the approved customer signed off "golden" sample.
Full disclosure is essential in meeting short and long-term goals. This should include past history as well as current status.
Jointly develop an action plan to resolve outstanding problems in accordance with future production needs and in order of importance. This will provide a successful foundation on which to build on.
