Artisan™ AR7300 PRE-COLORED FORMULATIONS PROCESSING GUIDE Artisan™ Pre-Colored Thermoplastics Artisan™ AR7300 pre-colored thermoplastics are customized ABS formulations to help manufacturers achieve brilliant and high-gloss metallic effect, excellent chemical resistance, and scratch resistance. Runners • Full-round runners or modified trapezoid runners are the best designs. • Half-round runners are not recommended. • Only naturally balanced runner systems (“H” pattern) are recommended. • Runner diameters should not be less than the part thickness. • Runner diameter should be 1.5x the part thickness. • Step each 90° bend in the system down in size. • Place vents at each 90° intersection and vent to atmosphere. • Hot runner molds are acceptable and should be sized by the manufacturer.

Global manufacturing and product stewardship support help mitigate risk Our manufacturing capabilities are deep and far reaching.
