Pro Tips

Always pre-dry ABS resin even if moisture content appears acceptable - residual moisture causes processing issues that aren't always immediately visible in finished parts.
Monitor barrel residence time carefully - ABS can degrade quickly at processing temperatures, especially in hot runner systems with long residence times.
Keep detailed processing logs linking material lot numbers to part quality - this enables rapid root cause analysis when quality issues arise.
Work with Colorado Sun Inc technical team to select the optimal ABS grade for your specific application requirements and processing conditions.
Establish statistical process control charts for critical dimensions and properties to detect quality trends before they become costly problems.
