Injection Molding of Bulk Molding Compound (BMC)
Injection molding of Bulk Molding Compound (BMC) is a manufacturing process used to form thermoset composite materials into strong, dimensionally stable parts with tight tolerances and repeatable quality. Because BMC is a thermosetting system, it cures irreversibly in the mold, meaning the finished component will not soften or re-melt when reheated, which is a major […]
Air Blast Systems in Injection Molding
Air blast systems are auxiliary devices integrated into injection molding machines to support tooling-related operations such as part ejection, localized cooling, and mold-surface cleaning. They work by delivering short, controlled bursts of compressed air through nozzles, ports, or dedicated air channels in the mold. When properly designed and tuned, these air jets help stabilize the […]
The Toggle Clamp (Injection Molding)
An injection molding machine’s clamping unit is responsible for one essential job: keeping the mold securely closed while plastic is injected, packed, and cooled. During these stages, internal cavity pressure can become extremely high. If the mold halves separate even slightly, the result is typically flash, dimensional variation, surface defects, and premature mold wear. A […]
