by Jay Perry With the increasing popularity of the in-mold labeling (IML) process for injection molding, electrostatics has emerged as an excellent option for IML. Applying the label during the molding process eliminates secondary operations, more importantly, the end result is permanent, which makes it especially attractive for product liability and instructional information, … [Read more...] about Electrostatics Advantageous for In-Mold Labeling

Flame Plasma Surface Treatment Improves Adhesion of Polymers
by Joseph DiGiacomo and Scott Sabreen Adhesion problems are widespread throughout the plastics industry and are increasing as metal components are being replaced by advanced engineering polymers. Many plastics have chemically inert and nonporous surfaces with low surface tensions that make bonding difficult. Most plastics are hydrophobic and are not naturally wettable. Surface … [Read more...] about Flame Plasma Surface Treatment Improves Adhesion of Polymers
