Incomplete technical documents cause 33 % cross‑border mold‑receiving disputes. Material records, simulation outputs, inspection reports and trial‑test data must be checked for LPDC, gravity and CPC counter‑pressure casting mold receiving acceptance.
H13 hot work steel receiving inspection shall verify steel mill material certificate, heat‑treatment report and multi‑point hardness test record. Missing these documents makes later failure‑analysis difficult once LPDC casting mold suffers early cracking in overseas aluminum alloy foundry.
Procast CAE simulation deliverables should contain filling, solidification and temperature‑field cloud images, plus parameter setting list. Receiving side needs to confirm alloy grade, heat‑transfer coefficient and mesh size used for gravity casting mold development.
Dimensional inspection documents include CMM measurement report, covering cavity contour, vent‑slot dimension and cooling‑hole position. Report must record measuring environment temperature 20±2 ℃ for CPC counter‑pressure casting mold EV structural‑part mold sets.
Pre‑delivery trial‑test documents require shot log, defect statistics, representative casting sample photos and key‑parameter curves. Pressure‑rise curve is mandatory item for CPC counter‑pressure casting mold receiving‑inspection technical package.
2D engineering drawings with revision status and 3D mold assembly model in neutral format shall be supplied. Using outdated drawing revision causes 22 % of assembly mismatch for cross‑border procured aluminum wheel LPDC casting mold.
Cooling‑channel pressure‑test record should show 0.8 MPa holding for 30 min zero‑leak result. Without leak‑test certificate, hidden water leakage risk may appear after installing gravity casting mold inside overseas foundry workshop.
Nitriding‑treatment inspection report records nitriding layer thickness 0.08‑0.12 mm and surface hardness data. Unverified nitriding quality leads to fast erosion of gating inserts for aluminum wheel mass‑production.
Spare‑parts list needs part number, material specification and dimensional reference. Vent inserts and gate inserts account for 64 % quick‑wear components for EV structural‑part mold; clear list supports later spare‑part ordering for aluminum alloy foundry.
Operating‑maintenance guidance covers suggested pre‑heat range, recommended cleaning cycle for vent‑slot, preventive‑maintenance cycle for H13 hot work steel inserts. Ambiguous maintenance guidance accelerates premature aging of LPDC casting mold in actual operation.
Acceptance checklist should mark which documents are original copies and which are certified copies. Cross‑border logistics may damage physical certificates; pre‑confirmed digital certified copies can support initial receiving inspection work.
Missing any core technical document shall trigger conditional‑acceptance mechanism instead of unconditional full acceptance. Clarify document supplement deadline to avoid blocking mass‑production preparation for overseas gravity and CPC counter‑pressure casting mold projects.
FAQ
Q: What material‑related documents are needed for H13 mold receiving inspection?
A: Steel certificate, heat‑treatment report and multi‑point hardness test records.
Q: What Procast CAE deliverables should be received with casting mold?
A: Cloud images plus parameter list including alloy grade and heat‑transfer coefficient.
Q: What pressure‑holding parameter for cooling‑channel leak‑test documentation?
A: 0.8 MPa hold for 30 min with zero‑leak as qualified test standard.
