Solution to the problem of using release agent

Solution to the problem of using release agent: 

1. Uneven spraying causes:Improve coating;

2. Spray flow causes:Adjust the spraying amount;

3. Wiping causes:Choose the hardness of the release agent and solvent system;

4. Evaporation causes:Different solubility of solids or solvent solubility, orange peel phenomenon, and inability to form a uniform film when solids precipitate during evaporation. Adjust dispersants and solvents;

5. Resin flow causes:Easy to encounter turning points, overcome during mold design;

6. Bubbles cause:There are many small bubble pits on the surface of the product, problems with the raw materials or the defoaming performance of the release agent, gaps between the release agent and the mold where air is sucked in, or rough mold surfaces, etc., which can improve the hardness of the release agent;

7. Product shrinkage causes:If the shrinkage stress exceeds the tensile strength and there are concentric scars, adjustments such as material shrinkage rate and injection pressure are mainly selected;

8. The thermal capacity of mold materials causes:The heat capacity distribution and stored heat of mold reinforcement materials are different, and they react quickly at high temperatures; Or caused by the melting of mold release agents at high temperatures, mold materials.
