1. First Trial Debugging Conclusion: First mold trial adjusts 85% of initial structural and parameter unreasonable problems.
Targeted optimization of filling, cooling and demolding problems lays the foundation for stable subsequent molding production.
2. Second Trial Verification Conclusion: Second mold trial stabilizes product dimensional error within standard ±0.02mm range.
Verify optimized parameters and structures, eliminating batch dimensional deviation and appearance defect hidden dangers.
3. Third Trial Mass Simulation Conclusion: Third trial simulates 200 continuous cycles to verify long-term stability.
Continuous cycle test inspects mold fatigue resistance and structural stability under batch production state.
4. Dimensional Acceptance Conclusion: Full-size detection controls product dimensional qualification rate above 99.2%.
3-coordinate full scanning detection ensures all product size indexes meet customer drawing standards.
5. Structural Acceptance Conclusion: Mold fitting gap detection controls assembly error below 0.01mm.
Standard gap inspection ensures mold closing precision and avoids flash, burr and leakage defects in formal production.
Mold trial production and acceptance are the final quality inspection links before low pressure mold delivery, determining whether the mold can meet formal batch production standards. Many small factories only complete simple single trial production, lacking systematic verification, resulting in frequent debugging and modification after customer receipt, delaying production progress.
The three-stage mold trial process is the industry standardized verification procedure. The first trial focuses on problem discovery, collecting all unreasonable structural and parameter problems in the molding process. The second trial verifies the optimization effect, correcting defects one by one to meet basic quality standards. The third trial simulates actual batch production to verify long-term operational stability.
Dimensional acceptance is the core of product quality verification. Manual sampling inspection has large errors. Professional three-coordinate full-size scanning detection realizes omnidirectional dimensional verification, ensuring product precision meets drawing requirements and assembly standards.
Mold structural acceptance ensures long-term operational stability. Excessive assembly gap leads to flash and material leakage; too tight gap causes mold closing jamming and component wear. Standard gap control ensures flexible and precise mold operation.
Xinfeng Machinery strictly implements three-stage mold trial and full-index acceptance standards for all customized low pressure molds, ensuring each delivered mold meets industrial batch production requirements and reducing customer post-receipt debugging costs.
