A new French Vision Series vacuum hydraulic press model, available from 30 to 150 tons, is specially designed for customers moulding composite parts.
According to French, the Vision composite moulding press, pictured in a 50 ton model, features electrically heated platens with a steady state working temperature of 500° F. The platens are also further drilled for water cooling circulation. The press construction has slab sides with keyways machined in sets to provide correctly proportional loading and exact parallelism of matching components.
French explains that the vacuum chamber is formed by heavy duty doors that are mounted to the front and back sides of the press. The front door moves up and down based on the press automatic cycle and the rear door is hinged to allow ease of press service. The vacuum pump eliminates entrapped air and moisture in the composite materials and removes entrapped volatiles caused during the moulding process that can reduce part quality. A vacuum transducer is incorporated in the press system to indicate and control vacuum, which can be based on preset timers or vacuum level parameters. The press pump can be sized to draw full vacuum in 2 minutes or less, for faster cycle time.
The press includes a microprocessor-based advanced control system, designed by French and TMP, A Division of French engineers to improve part quality through better processing accuracy, repeatability and versatile process-control programming to monitor data for user analysis. The colour touchscreen is operator-friendly and the system is easily utilised to program the machine recipe and control moulding parameters such as platen temperature set points, hydraulic pressure and pressure de-gas for the automatic cycle. Temperature and pressure ramp rates are also easily programmed.
As an example of French’s commitment to quality, the press comes with a three year warranty from date of shipment. French’s personnel will travel to the customer’s plant for installation, training and ongoing service as requested.
Customers may choose from a variety of additional press options including loading and unloading automation, more robust recipe storage and data collection, high temperature heated platens and platen cooling. In addition, specialised UNI-TEMP platens for even more advanced temperature control are available.
