Why do my parts have sink marks?
Sink marks usually appear when there's insufficient holding pressure or short holding time. I recommend:• Increase holding pressure by 10-15%• Increase holding time• Check gate diameter (min. 80% of wall thickness)
What resin do you recommend for high-impact resistant parts?
For high impact resistance, the best options are ABS, PC/ABS, or TPE. If you also need chemical resistance, consider PP with impact modifier.
