Purging compounds offer significant cleaning efficiency compared to using resin alone, often reducing scrap and less machine downtime. However, many people mistakenly assume that purging compounds are "expensive" compared to resin. A suitable purging compound can save your company time and money.
When using the proper grade of purging compound, the cost savings often outweigh the initial expense. Satisfied users worldwide report that effective purging reduces scrap, increases machine uptime, and improves overall efficiency. In short, the right purge pays for itself and continues to deliver savings.
Cost Analysis of Purging Methods
Evaluating all factors involved is essential to assess the cost of purging. Whether you're purging with virgin resin, regrind, or a commercial purging compound, the same metrics apply to measure cost-effectiveness. These include:
- Machine downtime (including teardown for manual cleaning)
- Amount of purge or resin used
- Scrap generated before the next good part is produced
- Corresponding costs of each step
Calculating the "total purge cost " allows you to compare different methods and identify the most cost-effective solution. Production teams are best equipped to conduct this analysis and ensure efficient operations. It should only be used if a purging method is more cost-effective.
Avoiding Costly Mistakes
That said, following recommended procedures and avoiding using purging compounds wastefully is essential. Using the wrong grade of purging compound can also lead to inefficiencies. For example, a compound that works for one job might not be suitable for another, especially if you're dealing with hot runners, die heads, or thermally sensitive resins during shutdowns.
Failing to communicate with your purge supplier about changing applications can result in running larger quantities of the wrong grade, leading to higher costs. However, this isn't a flaw in the purging compound itself—it results from improper usage or process misalignment. Like any other product or process, purging compounds should be carefully evaluated and qualified for each application to maximize efficiency and savings.
