In the custom‑molding world, you face a relentless combination of variables: dozens of colors and materials, high‑cavitation molds, hot‑runner systems, and tight turnaround demands. Your reputation depends not only on meeting delivery schedules, but on delivering defect‑free parts every time. When changeovers drag, scrap piles up, or contamination slips into your parts, it isn’t just a productivity hiccup—it can threaten your contracts and margins.
That’s why an effective purge program is a secret weapon for custom molders. For more than 25 years, Asaclean® Purging Compounds have supported shops like yours, helping reduce changeover times, eliminate scrap, and regain control of operations.
Why Changeovers and Contamination Hit Custom Molders Hard
Custom molders are uniquely challenged: you might be switching from a PP cap mold one hour to a medical housing the next, then a filled engineering‑resin part late in the day. Each transition means a chance for carry‑over, color streaks, black specks, or worse. When changeovers are unpredictable or lengthy, downtime and scrap become hidden costs that erode profit margins.
There’s a real quote from a custom‑molding shop that illustrates this:
“We run about twenty different colors and we don’t have to pull our screws. We don’t have to do anything additional other than running the Asaclean® between colors. We never have contamination issues or streaking.”
When you consider that Asaclean®’s custom‑molding customer base reports they save on average 57 % on scrap and downtime, the value becomes clear.
What a Smarter Purge Program Looks Like
A strong purge program goes beyond throwing in a generic cleaner and hoping for the best. It involves partnering with experts, standardizing procedures, tracking baseline metrics, and using purging compounds matched to your process. For custom molders, this means selecting purge grades that work in hot runners, multi‑cavity molds, filled materials, and aggressive changeovers.
By doing so, you can accomplish:
-
Faster, more predictable color and material changes
-
Easier cleaning of hot runner manifolds, valve gates, and nozzle tips
-
Fewer screw pulls and less emergency maintenance
-
Lower scrap rates and higher overall line uptime
With a structured purge program in place, you shift from reactive cleanup to proactive production.
Real Benefits That Drive Business Value
When your molders, maintenance teams, and operations leaders see faster changeovers, fewer defects, and repeatable results, the impact spreads across the organization. Maintenance can focus on preventive tasks instead of fire‑fighting. Production plans stay on schedule. Buyers gain confidence in resin sourcing and inventory management. Every department appreciates fewer surprises—and your clients get reliable delivery and quality.
When you dig into numbers, the return becomes impossible to ignore. A custom‑molding shop employing Asaclean® reported tens of thousands in annual savings by cutting scrap and downtime. With standardization and training, these savings grow with time.

The Bottom Line
For custom molders, every minute of downtime and every part of scrap counts.
