Blow molding is a widely used process in the manufacturing of plastic parts, particularly in industries like packaging, automotive, and consumer goods. One of the most common challenges faced by blow molding operators is carbonization, a phenomenon that occurs when plastic material is exposed to excessive heat for too long. This issue not only affects the appearance of the final product but can also compromise its structural integrity, leading to increased costs and reduced production efficiency. In this article, we will explore the causes of carbonization in blow molding, how to prevent it, and effective treatments for dealing with the problem.
