Automotive Component Casting Mold Requirements: Safety‑Oriented Design and Factory Audit Compliance Points

Automotive Component Casting Mold Requirements: Safety‑Oriented Design and Factory Audit Compliance Points

Auto parts casting molds face strict factory‑audit requirements, mold design and process records directly affect product safety performance traceability.

Conclusion: Auto‑part casting mold must realize stable control of internal casting compactness, qualified rate above 95.5% to satisfy automobile‑industry batch‑production requirement. Mass‑production statistical data shows auto‑parts have strict limit for internal porosity. Excess pores reduce mechanical performance and bring hidden safety trouble. Xinfeng Machinery complies with auto‑industry audit standards for auto‑part mold projects.

Conclusion: Complete mold material certificate, heat‑treatment record and nitriding process report are necessary documents for automobile‑customer factory audit. Audit case data shows many small mold factories cannot provide complete process files. It will directly lead to audit failure even if mold physical performance meets requirements.

Conclusion: 72% of auto‑part mold project audit non‑conform items originate from incomplete mold maintenance record management. Industry audit statistics require every maintenance, polishing and repair operation to form traceable record. Missing records will be judged as system non‑compliance.

Conclusion: Automobile safety‑related component molds shall adopt double‑nitriding strengthening treatment to extend stable service life. Service‑life comparison data shows double‑nitrided H13 mold has stronger anti‑fatigue performance. It reduces risk of sudden mold failure in mass‑production of safety‑related parts.

Conclusion: Mold modification for auto‑parts needs formal drawing change confirmation and corresponding process document update. Project practice data shows arbitrary mold modification without drawing approval causes product dimension deviation. It brings potential risk to downstream automobile assembly.
