TWX-RⅢ Series was developed from the best-selling hybrid type vertical machine "TNX Series," which was widely used in many insert molding industries. This new hybrid type vertical injection molding machine is equipped with a new compound type clamping mechanism and offers super low-profile structures. It provides high safety and refined usability while reducing the costs for ancillary equipment and hydraulic oil.
In spite of being 220t and 300t class vertical injection molding machines, the heights of the mold mounting faces are 1,000mm, offering significantly lower height than its predecessors. It makes mold installation/setup, insert, and product takeout easier than ever before, significantly improving the usability and operability. Its optimized bed structure permits flexible robot layout. It also offers wider mold open/close stroke and maximum daylight opening, accommodating for the trends to use more complex and larger mold.
TWX-RⅢ Series is equipped with a direct-pressure type clamping mechanism that constantly transmits clamping force evenly to the mold according to the setting, even though it is a turntable type that mounts two molds on the lower die. Its performance is not affected by the temperature change in the mold or clamping unit. It’s easy to set optimal (low) clamping force to be gentle to the mold and machine; its simple and clean mechanism maintains the machine precision for a long time.
Nissei can suggest automated insert molding systems that maximize the advantages of the vertical rotary machines, which incorporate takeout robot, articulated robot, and two-arm robot ideal for different molded products and molding processes.
