New hybrids weigh in. (Keeping up with Injection molding).New and larger units as well as units for thermoset A polymer-based liquid or powder that becomes solid when heated, placed under pressure, treated with a chemical or via radiation. The curing process creates a chemical bond that, unlike a thermoplastic, prevents the material from being remelted. See thermoplastic. molding were added to the Nadem line of hybrid presses from Meiki Co. Ltd. of Japan (represented here by Meiki America Corp., Elk Grove Village Elk Grove Village, village (1990 pop. 33,429), Cook and Du Page counties, NE Ill., a suburb of Chicago; inc. 1956. With a population of c.100 at the time of its establishment on open farmland, the village has grown dramatically and steadily, largely because of its , Ill.) Nadem machines have a hybrid, non-toggle clamp clamp (klamp) a surgical device for compressing a part or structure. rubber dam clamp a metallic device used to retain the dam on a tooth. clamp n. with electric opening and closing and a self-contained hydraulic clamp-up system that uses only 1 gal of oil. Meiki is expanding this line that formerly ranged from 88 to 550 tons with new models of 715, 935, and 1430 tons (pictured). Meiki plans to roll out a 2000-tonner in about a year. Initially, the new models will be available only in Japan. Meiki also introduced a hybrid unit for thin-wall molding. The Nadem 1500II-DM (165 tons) uses a central clamping clamping (klamp´ing) in the measurement of insulin secretion and action, the infusion of a glucose solution at a rate adjusted periodically to maintain a predetermined blood glucose concentration. cylinder for injection-compression techniques and relatively slow (350 mm/sec) injection. The high-response motor can accelerate the hydraulic injection unit from zero to peak injection speed in 16 millisec. Meiki also brought out its first hybrid unit for thermoset molding, the 165-ton Nadem 1500II-TS. It is based on Meiki's MC-TS series but is designed to allow for degassing degassing (dēgas´ing), adj related to degasification, the process by which dissolved gas is removed from water or other liquid solutions. and to address problems of insufficient torque during plastication previously experienced with all-electric systems, the company says.
