Compact All Electric Injection Molding Machine with Large Capacity CL7000

Masahiro HAYAKAWA and Yoshihiko MAKINO

In 2008, we developed a fully motorized injection molding machine CL7000 as a successor to SE550S (mold clamping force:5500kN). With its machine concept of "compact machine for large works" CL7000 not only achieves a large capacity with machine specifications (those related to mold size, in particular) being equivalent to competitors’6500kN-class models, but is also compactly built by incorporating various advanced functions. As a result, CL7000 is capable of molding products that have previously been produced with 6500 kN-and 8500kN-class molding machines in a lean and defect-free manner. This paper introduces the various advanced functions of CL7000 and examples of molding using CL7000.
