The K350 S injection molding machine is designed for demanding stack-mold and multishot applications with up to four injection units. The machine features a clamp force of 3500 kN (385 tons), maximum
injection weight of 884g, and a peak injection rate of 117.3 cu inches/second. It is a high-performance hydraulic machine, using an all-encompassing accumulator package and 55-kW (75-hp) variable-volume pump. The latter reduces energy consumption, and the former provides high-flow/pressure hydraulics for con-current operation of all machine functions.
The K 350?s fully hydraulic clamp unit, with generous daylight and clamp stroke, easily accepts large stack molds, and provides protection of tooling. It features platens of 38.2 sq inches, with maximum daylight of 47.2 inches, and tiebar spacing of 24.8 inches.
The accumulator-based hydraulic system provides filling of multiple cavities and parallel operation of shot recovery during mold movement for maximum efficiency in stack-mold applications. Tonnage build time is short due to the prefill tank being located directly above the closing cylinder, enabling rapid cylinder strokes. Pricing information not provided.
