The FWX Series is equipped with what Nissei describes as a new compound-type clamping unit, which enables significant downsizing. Nissei says this clamping unit design consists of a high-speed cylinder, high-pressure clamping cylinder and half-nut mechanism, which replace a conventional cylinder that controls both high-speed clamping and high-pressure clamping with a single clamping cylinder.

In terms of potential footprint reduction, as a Nissei spokesperson explained to Plastics Technology, when comparing a FWX760III machine with other machines that have the same or similar tie bar clearances, if, based on clamping force, a one class smaller machine can be used for an existing mold, it would occupy roughly 15% less space. If two-class downsizing is possible, which depends on the mold and process, about 30% space saving is possible. “The FWX redefines the way of choosing a machine,” Nissei stated in a release, saying selection could be based on mold dimensions rather than tonnage.

In this collection, which is part one of a series representing some of John’s finest work, we present you with five articles that we think you will refer to time and again as you look to solve problems, cut cycle times and improve the quality of the parts you mold.

Nissei is positioning its new FWX Series of hybrid injection molding machines as offering molders the potential for unprecedented space-saving and press-downsizing opportunities. Available in a tonnage range from 309 to 1,439 tons, with a 309-ton FWX760Ⅲ-130B version in Orlando, the FWX line was developed under the concept of “2-Class Larger Mold, 2-Class Smaller Machine.” Under this, if a hypothetical machine range’s normal array of clamp force tonnages with four sizes — A, B, C and D, where “A” being the largest and “D” the smallest — is considered, a tool that a molder would expect to require an “A” size press for could potentially use a “C,” if they also apply Nissei’s N-Sapli low-pressure technology.

The two-color injection molding process has been simplified through a development at Trelleborg Sealing Solutions (Stuttgart, Germany) that employs a single shot and a single tool to manufacture partially colored liquid silicone rubber (LSR) components. Utilizing an innovative and proprietary tool construction, the process has the capability to add color pigment to part of the transparent silicone material stream just prior to its injection into the tool cavity.

In addition, Nissei will feature a new tonnage vertical hybrid press — a 331-ton TWX300RⅢ36V — which also utilizes the compound, direct-pressure clamp. The TWX’s clamping mechanism emables a lower mold-mounting height of 40 inches, as well as an overall lower machine height, for improved worker ergonomics. The machines can also operate in facilities with lower ceilings.

Mold maintenance is critical, and with this collection of content we’ve bundled some of the very best advice we’ve published on repairing, maintaining, evaluating and even hanging molds on injection molding machines.
