MEAF Machinery - Thermoforming

Application

Thermoforming mould equipment.

Customer

MEAF Machines B.V. manufacture equipment for the plastics industry. They specialise in robust and compact sheet extrusion, thermoforming machines and auxiliary equipment.

The Challenge

Achieving higher mould forces, smoother motion profile and long service life. Providing higher possible mould forces and a smoother motion profile along with long service life was the goal for MEAF Machinery while designing their new KSM600 high capacity thermoforming machine.  This machine, utilising air and plug‐assisted forming, enables very accurate control of the wall thickness of the plastic to form ribs and contours, resulting in a final stable plastic product.

The Solution

Exlar’s roller screw actuator technology was chosen over less capable linear motion solutions for this application.  Ball screw average life expectancy would not meet the service requirements of the KSM600 machine, whereas pneumatic cylinders could not produce a sufficiently high force and stiffness for pressing and rotating.

By choosing two Exlar FT60 actuators and one GSX60 integrated actuator, MEAF replaced the pneumatic plug drive and the cam system for opening and closing the mould.  Not only were the objectives of long life and increased load were met, but an electric cam profile provided by the Exlar actuators resulted in a smoother motion profile.
