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

阿科玛收购 Agiplast 以提供生物基、再生材料聚合物
Arkema acquires Agiplast to provide bio-based, recycled materials polymers

阿科玛公司表示将收购 Agiplast 公司，该公司是高性能聚合物，特别是特种聚酰胺和含氟聚合物再生领域的
领导者。通过计划中的对 Agiplast 的收购，阿科玛将能够在材料循环方面为客户提供全面的服务，满足这一领域
日益增长的市场期望。该交易预计将于 2021 年 6 月完成。
通过这次收购，阿科玛将成为第一家同时提供生物基和再生材料的全面整合的高性能聚合物制造商，以应对
资源稀缺和产品报废的挑战。这个项目有助于聚合物行业的可持续发展，与阿科玛的可持续增长战略完全一致。
Agiplast 是一家专门从事高性能聚合物再生的公司，是阿科玛在回收业务方面的历史合作伙伴。该公司的年
销售额约为 1 500 万欧元，在意大利经营一家工厂，拥有 32 名员工。Agiplast 在机械回收技术方面的强大专业
知识将使阿科玛能够向其客户提供高质量的再生聚合物。
®
2019 年 10 月，阿科玛已经启动了 Virtucycle 项目，这是一项与 Agiplast 合作的雄心勃勃的计划，旨在开
发高性能聚合物的收集和再生循环，同时最大限度地减少二氧化碳排放。因此，这一额外的收购符合阿科玛的企
业社会责任和可持续增长战略，特别是向循环经济的过渡。
