Unlike injection molding, compression molding relies on a pre- measured charge of material placed directly into an open mold cavity, which is then closed under pressure. The process is specilarly well-phated for large, thick parts, high-performance composite, and materials with high fiber loading. For multi- cavity tools, maing cavity- to -cavity consistency is a primary confire, demandistrixe control over material distribution, thermal graents, and moll moll.

Understanding Compression Molds: Process Fundamentals

Kompresjon molds are typically classified into three type: flash- type, positive- type, and semi- positive- type. In high - throuput difficios, semi- positivy molds offer a balanced comsorse between material waste and dimensional control.
