Here‘s Our Common Question

• The size of the glassware does not meet the design requirements

  Strictly control the composition and particle size of raw materials to ensure the quality and stability of glass melt;
  Adopting high-precision molds and processing techniques to improve manufacturing accuracy;
  Uniformly stir the glass melt to prevent component segregation and bubble formation;
  Adopting advanced molding processes and technologies such as rolling and dripping to improve molding accuracy.

• The surface of glassware is not smooth or even

  Improve the temperature and uniformity of glass melting, reduce the influence of impurities and gases;
  Select high-precision and high smoothness mold materials and processing technology to improve the smoothness and accuracy of the mold;
  Control the cooling rate and temperature gradient to make the glass surface smoother;
  Polish the surface of the glass to improve its smoothness.

• Cracks appearing on the surface or inside of glassware

  Increase the uniformity and stability of glass melting, and reduce the generation of stress;
  Optimize mold design and processing technology to avoid stress concentration and damage to the mold;
  Control the cooling rate and temperature gradient to reduce the generation of thermal stress;
  Annealing treatment of glassware to eliminate internal stress.

• Obvious and regular stripes appearing on the surface of glassware

  Ensure the purity and uniformity of glass raw materials, reduce the formation of impurities and stripes;
  Adjust the melting temperature and time to fully fuse the glass melt and reduce the occurrence of stripes;
  Select appropriate mold materials and processing techniques to improve the smoothness and accuracy of the mold, and reduce the generation of stripes.

• Bubbles on the inner or outer surface of glassware

  Increase the melting temperature to fully eliminate gases from the glass melt;
  Reduce the cooling rate to allow more time for gas to escape from the melt;
  Check whether there is excessive gas in the raw materials;
  Increase agitation of the glass liquid to promote uniform distribution and upward movement of gas.
