Electrostatic discharge (ESD) is an often-overlooked yet critical concern in the packaging and handling of certain types of beads, particularly those made with or incorporating materials sensitive to electrical charge buildup. In bead manufacturing environments, especially those producing electroplated, metallized, resin-based, or electronic-interfacing beads, static charges can accumulate during various stages of processing and packaging. …

In the production of epoxy-filled beads, curing is a critical phase that determines the final mechanical strength, adhesion, clarity, and long-term durability of the product. These beads, often used in jewelry, accessories, and decorative applications, are filled with epoxy resins that may be clear or colored, embedded with glitter, pigments, or miniature inclusions. The curing …
