KraussMaffei adds MX SFT mold carrier to its TechCenter

The new MX SFT mold carrier supports development, prototyping and production of fiber-reinforced plastics.

KraussMaffei Reaction Process Machinery (Munich) has expanded its TechCenter for lightweight components and fiber composite technology at the Munich location with the addition of a new MX SFT mold carrier. The new mold carrier, which boasts a clamping force of 8,000 kN, reportedly features very high locking forces and fast run times.

"Demand for new fiber-reinforced composites is unhindered. The addition of the new mold carrier to our TechCenter provides our customers with optimum prerequisites for developing and testing processes and solutions tailored to series production," says Stefan Ehrlicher, head of the RPM (Reaction Process Machinery) TechCenter at KraussMaffei. For example, the new MX SFT mold carrier is ideal for the entire range of RTM processes (resin transfer molding), such as high-pressure RTM (HP-RTM), compression RTM (C-RTM), surface RTM (S-RTM), thermoplastic RTM (T-RTM) and even wet molding. "Even OEMs and tier 1 suppliers outside of the automotive industry utilize the unique options for prototype development and proving in our TechCenter," says Ehrlicher.

The new mold carrier can be combined with almost all of the available metering machines in the KraussMaffei TechCenter. An epoxy RTM machine is permanently installed in combination with a release agent unit and an industrial robot for open injection (wet molding).

The high positioning accuracy and bending stiffness provided by the four-column concept makes it possible to use molds suitable for series production to manufacture structural or surface parts in single cavities or multiple cavities. This considerable holding force in the mold carrier system is made possible due to hydraulic locking cylinders over the entire press stroke. The use of differential cylinders ensures extremely short cycle times and very high speeds. At the same time, the SFT design concept from KraussMaffei enables a power flow and a high level of stiffness (FEM-optimized).
