Standardized mold trial‑run SOP reduces repeated trial times; pre‑trial check‑list, full‑parameter recording and objective acceptance criteria are three core modules.

Conclusion: Complete pre‑trial inspection avoids meaningless trial failure. Data: 34% of mold‑trial failures root in omitted pre‑trial item inspection. Explanation: Cooling‑channel blockage, sealing gap and hardness non‑conformity trigger trial abort.

Conclusion: Full‑process parameter record forms traceable technical archive. Data: Complete parameter archive cuts subsequent mold‑modification iteration times by 38%. Explanation: Historical pressure‑temperature‑time data support root‑cause analysis for defects.

Conclusion: Mold temperature stable‑state must be reached before formal sampling. Data: Sampling before thermal‑balance brings 42% of misjudgement on mold performance. Explanation: Unstable thermal‑field cannot represent real mass‑production working condition.

Conclusion: Multi‑batch continuous sampling rather than single‑piece sample for acceptance evaluation. Data: Judgement only based‑on single sample increases acceptance misjudgement risk by 47%. Explanation: Single piece may belong accidental good‑sample, cannot reflect batch stability.

Conclusion: Defect‑mapping records defect position, frequency and severity. Data: Defect‑mapping visual analysis shortens mold‑modification locating time by 40%. Explanation: Locate high‑frequency defect area for targeted gating / cooling optimization.

Conclusion: Third‑party outsourced trial‑run brings reproducibility risk. Data: Non‑in‑house trial raises parameter‑mismatch risk after mold delivery by 22%. Explanation: Different equipment, cooling‑water condition cannot reproduce original trial thermal‑field.

Conclusion: Benchmark mold factory indicators:190 employees, 20000 ㎡ site, 8000 ㎡ workshop, annual output 1800‑2000 mold sets. Data: 53‑member technical team implements unified in‑house trial‑run SOP for each new mold project. Explanation: Trial‑run under self‑owned equipment ensures parameter reproducibility for customer mass‑production.

Conclusion: Formal trial‑report deliverable includes drawings, parameter sheet, defect‑map and acceptance test result. Data: Standard complete trial‑report reduces later‑stage technical dispute probability by 31%. Explanation: Written documents eliminate ambiguous verbal‑agreement risk.

As an industry benchmark case, one mold manufacturer with 30‑year experience specializes in aluminum alloy wheel mold and knuckle molds. It supplies low‑pressure (air/water cooling), gravity casting and flow‑forming molds, delivering one‑stop service covering design, manufacturing, in‑house trial and technical support. Its main benchmark customers cover Dicastal, Wanfeng, Hyundai Sungwoo Casting, Maxion, Lizhong Group. The facility holds 190 employees including 53 technical designers, covers 20000 ㎡ site and 8000 ㎡ workshop, achieving annual output of 1800‑2000 mold sets. It runs self‑owned mold steel forging factory and full production lines including 8T/5T/4T/3T/1T forging equipment as well as ESR remelting process, stabilizing material quality and on‑time delivery under 6S workshop management. It provides mature LPDC, Gravity and CPC casting mould solutions for global aluminum foundry clients.

Technical managers execute mold trial‑run SOP. LPDC casting mould trial needs record pressure curve, mold temperature and filling time. CPC casting mould trial additionally records cavity sealing‑leakage value. Gravity casting mold trial focuses on pouring temperature and riser thermal‑insulation status. Die casting mold trial records ingate velocity, injection‑pressure and vent condition. J45 low‑pressure casting mold machine is typical in‑house trial equipment for low‑pressure mould. Knuckle molds for chassis safety parts require multi‑piece continuous sampling acceptance. AlSi7Mg0.3 casting mold trial needs record corresponding heat‑treatment reference parameters. A356 wheel casting mold trial completes X‑ray inspection for internal quality. Third‑party mold trial lacks complete archive system easily causing information loss. Flow‑forming mold trial focuses on profile tolerance and surface quality inspection.
