1.Surface damage or wear of graphite molds:
Cause: Prolonged use or processing of hard materials may lead to surface wear.
Solution: Regularly inspect graphite molds and, if necessary, perform grinding or repairs.
2.Cracking or fracturing of graphite molds:
Cause: Rapid temperature changes, stress concentration, poor design, among other factors, may cause molds to crack or fracture.
Solution: Control temperature variations, design a structurally sound mold, choose appropriate graphite materials, and avoid stress concentration.
3.Difficulty in demolding products:
Cause: Rough graphite surface, insufficient lubrication, or poor design may make products challenging to demold.
Solution: Improve the smoothness of the graphite surface, use suitable lubricants, optimize mold design to ensure easy demolding.
4.Deformation of graphite molds:
Cause: Graphite tends to soften at high temperatures, and prolonged high-temperature operation may result in deformation.
Solution: Control temperature, use graphite materials resistant to deformation at high temperatures, and consider lowering processing temperatures.
5.Oxidation of graphite mold surfaces:
Cause: Prolonged high-temperature operations, exposure to oxygen in the air, and other factors may lead to oxidation of the graphite surface.
Solution: Control the operating environment, avoid prolonged high-temperature operations, and choose graphite materials with good oxidation resistance.
6.Inaccurate dimensions of graphite molds:
Cause: Measurement errors during manufacturing, material thermal expansion, and other factors may result in inaccurate dimensions.
Solution: Optimize manufacturing processes, use high-precision equipment for measurements, and consider the thermal expansion of materials.
7.Difficulty in cleaning graphite molds:
Cause: Accumulation of residues or material remnants on the mold surface.
Solution: Regularly clean the mold surface, use appropriate cleaning agents, and ensure that the mold surface remains clean.
It’s important to note that specific solutions may vary depending on the circumstances, and seeking advice from professionals or the manufacturer is advisable. Additionally, regular maintenance and care of graphite molds are crucial for ensuring their long-term stable operation.
