Abstract: Compression and injection molding use different types of plastics, the former using thermosetting
plastics, the latter using thermoplastic plastics. Compression molding technology and mold design is
a developing comprehensive science. It not only improves with the improvement of polymer synthesis
technology, the renewal of molding equipment and the maturity of molding technology, but also with the
development of computer technology, rapid molding technology, numerical simulation technology, digital
application technology, intelligent technology, etc. The main contents of this lecture include: compressing
molding technology and classification, compressing molding parts design, compressing mold structure design
and parts design, compressing molding equipment, quality control and defect analysis of compressing
molded parts, application examples of compressing molds, principle and process of injection-compression
molding, structure design of injection-compression mold, calculation of injection-compression molding
pressure, selection of injection-compression molding equipment, quality and defect analysis of injection-
compression molded parts, application examples of injection-compression molds.
Key words: design and forming of compression molded part; compression molding technology and mold
structure design; compressing molding equipment; quality and defect of compressing molded part; selection
of injection-compression molding technology and equipment; structure design of injection-compression mold;
quality and defect analysis of injection-compression molded part
