[Plating Testing and Evaluation Methods] Evaluation Method for Plated Coatings - Adhesion Quality

We customize the evaluation methods according to the customer's product and conduct the assessment!

There are various methods to evaluate the adhesion of plating films, and I will introduce a few of them. The "tape test" is easy to perform and is a formal test specified in JIS H 8504. We often use it in our company, and when evaluating multiple levels of processing conditions, we can determine superiority or inferiority based on the number of squares that have peeled off and the manner in which they have peeled. Additionally, since we have many small parts, we do not conduct it, but there is also a testing method called the "bending test." There are other testing methods such as the extrusion test and the file test, and in our company, we customize the evaluation methods according to our customers' products. Please feel free to contact us when needed. 【Tape Test Procedure】 1. Leave a 30-50mm area without adhesive tape and firmly attach the tape to the plating surface. 2. Hold the unadhered part of the tape and quickly and strongly pull it off so that it is perpendicular to the plating surface. 3. Check the removed tape; if there is any plating adhesion, it is judged as poor adhesion. *For more details, please refer to the PDF document or feel free to contact us.
