Abstract
In this study, the physical performance (adhesion resistance, heat resistance, abrasion resistance, chemical resistance) extremely thin, highly durable and chemically adsorbed fluorocarbon film with low surface energy on the metal surface (the thickness is about 1 nm order.) was evaluated, and the evaluation results (durability, demolding resistance) on the actual injection molding performance up to 100,000 shots using a test mold were reported.
The demolding resistance could be drastically decreased without losing the mold shape and dimensional accuracy by using the chemically adsorbed and highly durable fluorocarbon film.
From these results, this technique should be useful for molding various elastomers such as silicone and urethane resin which are difficult to release from a mold for making high precision products such as optical components and chemical chips.
