Meaning
Contractual provisions ensure that modifications to a manufacturing process undergo formal review and approval before implementation. management of change clause protects the buyer from unannounced alterations in resin grades, tool configurations or additive packages that might affect part performance, and it stops applying once a new validation cycle is completed.
Approval Sequence
Suppliers must submit a written notification before changing a raw material source or a production location. The buyer then reviews the proposal to determine if the change requires new testing or a full part requalification. This formal step prevents the introduction of unknown variables into a stabilized supply chain.
Quality Risk
Minor adjustments in a resin formulation can lead to unexpected changes in shrinkage or environmental stress crack resistance. A molder might switch to a cheaper stabilizer that looks identical on a datasheet but fails during long-term use. The clause forces these risks into the open before they cause field failures.
Supply Stability
Sudden changes in processing parameters can alter the dimensions of a precision part. By requiring a notice period, the contract ensures that existing stock is sufficient to cover any delays caused by the revalidation of the new process. This continuity is vital for high-volume automotive or medical production lines.
