POOR TEXTURE OR ENGRAVING REPRODUCTION

Improper molding temperatures • Increase the blow mold temperature. • Increase the parison mold temperature. • Increase the melt temperature. • Verify the mold temperature controller is operating correctly. • Increase core pin cooling. Mold surfaces need cleaned or refurbished • Clean the engraving. • Sandblast/retexture the molds. • Adjust engraving depth and width. Improper blow pressure or timing • Increase the air blow pressure. • Increase the air blow delay. • Clean/check all gaps in the core rod valve. Poor venting • Improve the blow mold's venting.
