Errors in mold release agent usage decrease product quality and increase mold maintenance needs. Incorrect applications can lead to surface defects, painting problems, and production inefficiency.
Errors in mold release agent usage
1. Excessive release agent use
- Causes buildup on the mold surface
- Can create oil traces, dullness, and surface defects on the part
- Can clog vent channels
2. Incorrect release agent selection
- Using a product unsuitable for the plastic raw material
- Choosing a silicone-based release agent for parts to be painted or glued
- Causing surface adhesion problems
3. Irregular application
- Spraying too much on some areas of the mold and too little on others
- Creating imbalance in part ejection
4. Applying to a dirty mold
- Spraying release agent on an uncleaned surface
- Increasing carbon and resin buildup
- Making mold cleaning difficult
5. Incorrect spray distance
- Too close application → dense buildup
- Too far application → insufficient coating
6. High-temperature incompatibility
- Using release agents with low thermal resistance on hot molds
- Causing burning and carbonization
7. Overly frequent use
- Excessive application in every cycle
- Residue buildup in the mold and increased maintenance needs
Recommendations for correct use
- Apply thinly and evenly
- Clean the mold regularly
- Select the appropriate release agent for the production process
- Painting/gluing needs should be evaluated in advance
