In Purging, Knowing is Half the Battle

Understand your needs before choosing a purging compound

Before I even think about what grade of purging compounds to recommend, the first thing I have a conversation and thoroughly understand the customer's needs. That means having an accurate assessment of the time and costs associated with color changes, material changes, contamination issues, and manual tear downs and cleaning to name a few. When sharing a conversation with production team members I typically find one of three things: 

  • 1. ) A complete and comprehensive understanding of time and costs.
  • 2. ) A loose interpretation.
  • 3. ) An understanding somewhere in-between. 

Understanding where you are and what you can expect is part of the process of determining value. In the cases where times and costs are broad-stroked, clarification is required. The best way to accomplish this is to monitor the need in question the next opportunity it arises and document the results. From there we can determine what you can expect with the use of your purging compounds. This is an easy process with the help of a Cost Savings Analysis (CSA).

The CSA can be used for all thermoplastic processors. It’s a terrific tool to better understand the times and costs of transitions. Best of all it’s free. Please take a minute to look. If you have any questions, please feel free to reach out for your free consultation.
