In the compression molding process, temperature, pressure, and time duration under pressure are important process parameters. From maintaining consistent heat throughout a specified dwell period to precision pressure ramping, and managing burp cycles, Shuntec custom-made heated platen compression molding presses help you perfect your forming operation.
Compression molding is a method of molding during which the preheated molding material is placed in a heated mold cavity. Then the mold is closed with a top force, which generates pressure forcing the material to contact all mold cavity areas. The heat and pressure will be maintained for a certain period of time until the molding material is cured and the desired product is obtained. Compression molding is one of the most cost-effective thermoforming methods for molding complex, high-strength products such as fiber-reinforced plastics, metal alloys, composites, and rubber.
With a working area up to 78 inches and tonnage up to 800 tons, Shuntec hydraulic compression presses machines are guided by quality graphite-impregnated self-lubricated bronze bushings and four solid, chrome-plated posts. The long bearing length provides perfect pressing stability and effective resistance to off-center loading. To ensure the perfect compression molding operation, The heated platens can be divided into multi-temperature zones to achieve uniform heat distribution and convenient temperature monitoring. The main pressing cylinder and multi auxiliary cylinders are designed for stable pressure cramping and burp cycle managing.
For fast set up into production, all compression molding presses in Shuntec can be offered with a 7-inch or 10-inch comprehensive HMI for parameter setting, data acquisition, and storage. A preheating device can be integrated or separated with the compression molding press.
