The NEX-Ⅳ Series by Nissei represents the latest advancement in all-electric injection molding machines, offering clamping forces from 30 to 360 tons (33 to 397 U.S. tons). Designed to enhance precision and efficiency, these machines cater to diverse manufacturing sectors, including automotive, medical devices, and consumer goods. The NEX-Ⅳ Series builds upon its predecessors’ success, incorporating innovative features to meet evolving industry demands.
Key features of the NEX-Ⅳ Series include a newly designed toggle mechanism that reduces mold open/close cycle times by 5–20%, and an ejector speed up to 19% faster than previous models, significantly boosting productivity. The enhanced “Flat Clamp Mechanism” ensures uniform contact pressure, extending the lifespan of both the mold and clamping unit. Standard linear guides for clamping slides improve rectilinearity, preventing molding defects and ensuring high-precision operations.
Choosing the NEX-Ⅳ Series offers substantial benefits, such as accommodating larger molds within a compact machine footprint, thanks to increased daylight and mold thickness ranges. This flexibility supports various mold types, including hot runner and long-length molds. The advanced “TACT® Ⅳ” controller, featuring a large 15-inch screen and user-friendly interface, enhances operability and facilitates efficient condition management, streamlining the molding process.
