| 二. Root Causes of Common Failures |
1.In Mold Transfer Silicone Incomplete Degassing:Air bubbles not only affect appearance but also weaken structural strength. During rubbing or washing, bubble areas tend to break first.
2.In Mold Transfer Silicone Difficult Demolding or Peeling:This often results from multiple combined factors-improper operation, unclean molds (residual silicone debris), incorrect vulcanization parameters, or excessive adhesion between silicone and mold.
| 三. Key Standards to Improve Yield Rate |
1.Environment and Tool Management:Store In Mold Transfer Silicone at 15°C–25°C in a cool, dry place. Reseal immediately after opening to prevent moisture absorption.Clean molds with a special cleaner after each use, wipe with a lint-free cloth, and keep free of dust or residue.
2.Parameter Standardization and Record-Keeping: Establish process cards specifying each step's parameters (e.g., mixing duration, vacuum time, vulcanization temperature). Regularly calibrate all equipment.
3.Operator Training:Provide focused training on even scraping and proper peeling techniques. Conduct simulation exercises to minimize human error.
