Injection Molding Machines

In order to produce plastic parts with high dimensional accuracy, injection molding machines are increasingly electrically driven. The electric press is superior to the traditional hydraulic type in that it is cleaner and uses less energy. Demand for it is growing in proportion to the need to respond to environmental issues.

With the shift to electric injection molding, customers now demand reliability in much harsher environments. NSK's high load capacity products are important parts, essential for mechanical drive parts, including the:

injection cylinder
mold clamping cylinder
ejector shaft
press cylinder
plasticization unit
Ball screws for high-load drives are one product NSK manufactures for injection molding machines. The arrangement of the circulation channels has been optimized, the diameter of the balls has been made as large as possible, and the ball groove has been designed especially for high loads. The ball screws have a greatly improved the load capacity.

Also, in support of these ball screws for high-load drives, NSK offers high load-bearing capacity ball screw support angular contact thrust ball bearings (for injection molding machines) that use large diameter balls, and roller guides produced with NSK's leading edge technologies and featuring high load capacity, high rigidity and the ability to be used in controlled clean environments. NSK is contributing to the future of injection molding machines as the only manufacturer that offers a comprehensive development and sales service for essential mechanical parts.
