In Situ Optical Surface Profilometry for Narrow Injection Mold Cavities
In situ optical profilometry resolves sub-micron cavity wear in narrow tool ribs using fiber-coupled chromatic sensors sealed behind purged sapphire windows.
Tool Transfer Clause
Meaning
Legal and operational terms in a manufacturing contract dictate the conditions under which an injection mold can be relocated from one molding facility to another. A well-defined tool transfer clause prevents disruptions to supply chains by clearly outlining who pays for shipping, who owns the tooling during transit, and what production records must accompany the mold. This protection is necessary when a buyer decides to change suppliers or bring production in-house.
Asset Ownership
Disagreements between buyers and suppliers often arise regarding the ownership of ancillary equipment like hot runner controllers or custom cooling manifolds. When a contract includes these details, it eliminates confusion about what parts of the tooling are proprietary to the moulder and what belongs to the customer. This clarity prevents protracted legal standoffs.
Verification Standard
Before a mold leaves the original supplier, a final production run must demonstrate that the tool is in working order. This requirement ensures that any defects or wear are documented before the transfer occurs, preventing the new supplier from blaming the previous operator for pre-existing issues. This documentation includes cycle time logs, maintenance history, and the latest sample parts to establish a clear benchmark for the incoming facility.
Financial Liability
The costs of packing, shipping, and re-validating the tool at the new facility must be assigned before the move begins. If a tool transfer clause is absent, disputes over these expenses can delay the startup of the new line. This delay can lead to stockouts and lost revenue for the buyer.
