Harmonizing Statutory Factory Liens with International Mould Tooling Ownership Contracts
Harmonizing statutory factory liens demands pre-filed property registrations, direct bailment agreements, and press-side asset engravings before shipping steel.
T1 Sample Qualification
Meaning
Initial part inspections performed on first molded components produced from a new or modified injection mold establish tool performance and dimensional accuracy. Quality engineers execute T1 sample qualification to verify cavity geometry, gate balance, and part dimensions against engineering drawings before approving mass production tool release. Initial samples are molded using baseline processing conditions specified during mold design.
Dimensional Audit
Coordinate measuring machines measure critical part dimensions across all mold cavities to check steel accuracy. Dimensional deviations indicate tool steel off-spec conditions, requiring sinker electrical discharge machining or hand polishing adjustments. Cavity-to-cavity variance highlights runner system imbalance or thermal non-uniformity across mold cooling channels.
Visual Inspection
Inspection teams examine T1 parts for visual defects such as sink marks, weld lines, flash, burn marks, and void formation. Sectioning thick part walls reveals internal voids caused by inadequate packing pressure or improper gate location. Surface gloss level measurements confirm core and cavity surface finish quality.
Tool Sign-Off
Molders submit dimensional measurement reports, part samples, and capability data to original equipment manufacturers for formal review. Meeting drawing tolerances authorizes tool modification for T2 sampling or grants full production release approval. Unresolved dimensional errors require tool modification and re-testing before commercial molding commences.
