Roof rim for trams in Karlsruhe When manufacturing and attaching the roof rim for trams in Karlsruhe, it was particularly important to ensure that the adhesive bond was secure. These dualsystem vehicles, which are manufactured by Bombardier, can reach speeds of up to 100 km/h. The GRP roof rim was attached to the vehicle body using an invisible aluminium bracket. The adhesive bonds between the aluminium and GRP were applied in accordance with DIN 6701, Class A1, and thoroughly tested in conjunction with the Fraunhofer Institut. FEM calculations demonstrate the permanent durability ofthe adhesive bond.

The optimum oscillation behavior of the ultrasonic sonotrodes is determined by means of FEM (Finite Element Method) calculation. Highest precision requirements in terms of CAD/CAM calculation algorithms guarantee precise 3D contours for sonotrode manufacturing. Measuring and documentation of the amplitude distribution is performed at the vibrating sonotrode using state-of-the-art laser measurement technology. Special surface finishings result in even longer service life spans of the ultrasonic sonotrodes.

SIMPAC presses with servo direct drive stand for highly dynamic forming processes and offer maximum flexibility in the production. In combination with a high stiffness value of press body and drive, they deliver consistently high part quality. Overview: ● Press capacity: 3,000 - 10,000 kN ● Part size: small to medium ● Slide kinematics: servo (freely programmable) ● Application: stamping, cutting, bending, embossing, drawing, integration of subsequent processes Features and benefits: ● Dynamic processes through the use of torque motors that provide high torque even at low speeds ● Maximum production flexibility due to freely programmable slide movement, slide velocity and stroke length ● Significantly higher output compared to conventionally driven presses due to reversing pendulum movement of the slide ● Very solid, FEM-calculated and low stress annealed press body

Compact presses for a wide range of medium sized parts. Due to its drive-related slide kinematics, the MCL series is particularly suitable for drawn parts. Overview: ● Pressing capacity: 3,000 - 8,000 kN ● Component size: medium ● Slide kinematics: link ● Applications: stamping, drawing, forming Features and benefits: ● The compact design requires little floor space and no foundation at presses below 4,000 kN. ● The very solid, low-stress annealed press bodies are FEM-calculated and optimized by so-called “hot-spot analysis” in areas which are subject to higher loads. ● Motor, clutch/brake unit, lubrication system and control are of German origin and guarantee a long service life and maximum dynamics. ● The slide guiding system ensures a high level of tilting rigidity and reduces the cutting impact during the cut through when it comes to the processing of higher-strength materials.

SIMPAC presses with servo direct drive stand for highly dynamic forming processes and offer maximum flexibility in the production. In combination with a high stiffness value of press body and drive, they deliver consistently high part quality. Overview: ● Press capacity: 8,000 - 30,000 kN ● Part size: medium to large ● Slide kinematics: servo (freely programmable) ● Applications: stamping, cutting, bending, embossing, drawing, integration of subsequent processes Features and benefits: ● Dynamic processes thanks to the use of torque motors that deliver high torque even at low speeds ● Maximum production flexibility through free programmability of slide movement, (forming) speed and stroke lenths ● Significantly more output compared to conventionally driven presses due to reversing pendulum movement of the slide ● Very solid, FEM-calculated and low stress annealed press body
