Clean machines are the foundation of efficient and high-quality blow molding operations. When machines are not thoroughly cleaned during resin or color changes, they can compromise the next production batch—resulting in defects, increased downtime, and avoidable losses.
If you’re unsure how to properly maintain your blow molding equipment, using a Purging Compound is a proven solution. Unfortunately, this process is often overlooked, leading to inconsistent results and production inefficiencies. Incorporating a Purging Compound for Blow Molding can significantly reduce downtime, streamline production, and enhance product quality.
Let’s Understand What Purging Compounds are and why they’re vital in the blow molding process.
What Is a Purging Compound?
A Purging Material is a specially formulated resin used to clean the internal surfaces of plastic processing equipment. In blow molding, these compounds are introduced into the machine to remove leftover materials—such as resins, pigments, and carbonized deposits—from previous runs.
When the machine is thoroughly purged, it’s free from contaminants that could affect the quality of the next batch.
There are Three Primary Types of Purging Compounds:
- Mechanical Purging Compounds: These physically scrub the interior surfaces to remove build-up.
- Chemical Purging Compounds: These use active agents to chemically dissolve and eliminate residues.
- Hybrid Purging Compounds: These combine mechanical and chemical actions for more powerful and efficient cleaning.
Why Purging Compounds Matter in Blow Molding
Reduces Downtime
Switching between resin types or colors can be time-consuming if done without proper cleaning. Using virgin resin for purging is both inefficient and costly. A Specialized Purging Compound reduces changeover time, helping your machines get back to full production faster.
Prevents Contamination
Issues like black specks or streaks are often caused by degraded materials left inside the machine. These lead to product rejections and financial loss. Purging Compounds effectively clean out residual resins and contaminants, ensuring a clean start for every batch.
Improves Product Quality
Clean machines produce better, more consistent products. Proper purging prevents color inconsistencies and defects, ensuring high-quality bottles, containers, and other molded items.
Saves Material and Costs
While Purging Compounds may seem like an additional expense, they reduce overall material waste and cut down cleaning time. Less resin is wasted, and production costs decrease in the long run.
Extends Equipment Life
Residual Material build-up can wear down equipment and reduce its efficiency over time. Regular purging protects critical machine components like the extruder, helping extend the life of your machinery.
