Given the specialized, precision-engineered, and delicate nature of molds, their protection is crucial. Key aspects include:
1. Rust Prevention
Preventing rust caused by water leaks, condensation, rain exposure, or fingerprints.
2. Impact Prevention
Preventing damage caused by broken ejector pins or pins failing to retract fully.
3. Burr Prevention
Preventing the formation of burrs caused by wiping with cloths, material impact, manual wiping, or contact with gate cutters or knives.
4. Missing Parts
Preventing damage during operation caused by missing components such as tie rods or washers.
5. Crushing Prevention
Preventing damage caused by clamping the mold while a molded part remains inside.
6. Low-Pressure Protection Issues
Preventing damage resulting from excessive low-pressure protection settings.
A significant proportion of mold damage-accounting for over 85% of cases-stems from broken or unretracted ejector pins, residual parts left in the mold, or missing accessories. Since mold repair costs are generally high, preventing these issues is directly linked to the profitability of the injection molding industry.
