Guidelines for Evaluating Price-Driscoll Products
Following these simple steps during a product evaluation ensures that results paint an accurate picture.
Performance and economy are worth watching. We suggest using the following steps to determine how well — and economically — your mold release is performing.
Take a scientific approach to your trials. Test several products at once. Follow specific standards and procedures with each product being tested. In this way, you increase the likelihood of an accurate performance rating.
Challenge the releases with the most difficult parts first. When you are satisfied with those results, move on to parts made of different resins.
Read the application directions. This is important and often overlooked advice. Some releases, evaporate quickly and dry almost instantly. Others have micro-droplets that may not reach the mold unless held at the recommended distance from the tooling. Follow the manufacturer’s directions.
Experiment to determine the product’s capabilities. Try increasing and decreasing the number of parts produced between applications. Applying a release too often costs money.
To make certain that residue from a previous release is not influencing a new product’s test results, stop production and thoroughly clean the mold between tests. Or, more efficiently, begin assessing test results after the new product is applied a half-dozen times.
Number the parts in the order they are molded. This helps in spotting patterns, like piece marking, crazing, etc.
When scrutinizing for adhesion problems, never spray release directly on parts. An excess of release will cause adhesion problems and provide inaccurate test results.
Maintain the same molding conditions throughout the trial. The best way to ensure conformity is testing all releases during one press run.
Include your press operator in the trial. Operators are the front line for spotting release problems and advantages. Be sure to solicit their comments and observations.
When you have narrowed the field down to one release, run another test using a new, full can of the product. Documenting the number of molded parts released by a product tells you its true cost.
A properly organized product trial provides valuable information. But, once again, consistency is the key.
