Rubber Molding Press Development from Compression to Injection and Vacuum Technologies

The earliest stage of Rubber Molding Press development was centered on compression-based forming, where raw rubber compounds were manually placed into heated molds and subjected to pressure through a Molding Hot Press system. This method relied heavily on mechanical or basic hydraulic structures, where pressure distribution and temperature control were relatively simple but still capable of producing durable rubber components. In this phase, the Rubber Machine operated with limited automation, and process consistency depended largely on operator experience and manual adjustments. Ningbo Delidong Machinery Technology Co., Ltd. has extensive experience in designing and manufacturing such foundational systems, ensuring stable structural integrity and reliable performance even under continuous industrial use. The compression Rubber Molding Press provided flexibility for producing thick-walled or large rubber parts, and it was widely applied in early automotive and industrial sectors. However, challenges such as uneven material flow, air entrapment, and longer curing cycles led to inefficiencies. The lack of precise parameter control often resulted in product variation, requiring additional finishing processes. Despite these constraints, compression-based Molding Hot Press systems established the fundamental principles of rubber vulcanization, including heat transfer, pressure application, and mold cavity design. Ningbo Delidong Machinery Technology Co., Ltd. integrates modern engineering improvements into traditional compression systems by upgrading hydraulic responsiveness and thermal uniformity, allowing these machines to remain relevant in specific applications.
