French Develops New Composite Molding Hydraulic Press for Aerospace Components

French Oil Mill Machinery Company recently developed a hydraulic press system to improve the part quality of critical composite aerospace components while dramatically reducing production cost, energy consumption and noise emissions. The downacting, sideplate hydraulic press system is designed with an Integrated RTM Package, a Precision Control Motion Package, specialized Uni-Temp platens for advanced temperature control, and the Edge II Control System, a specialized recipe and data collection system programmed to monitor critical processing data, insuring consistent results.

French Oil Mill Machinery Company and TMP, A Division of French, a custom hydraulic press manufacturer, recently developed a hydraulic press system to improve the part quality of critical composite aerospace components while dramatically reducing production cost, energy consumption and noise emissions.


The downacting, sideplate hydraulic press system is designed with an Integrated RTM Package and Precision Control Motion Package. Also included in the rugged design are French's patented tapered keys which extend the life of the headblock, sideplates and main cylinder. The reservoir and hydraulic power are mounted on top of the headblock, reducing the overall footprint of the press. A platform with ladder is provided to allow access and serviceability. The energy efficient hydraulic design reduces horsepower and noise throughout the molding cycle.

The press comes standard with steel, multi-zone electrically heated platens that are rated to 500º F and have nickel plated water cooling passages for corrosion resistance. Each platen includes edge insulation for enhanced temperature uniformity and provides three stages of cooling. Customers may choose to upgrade to specialized Uni-Temp platens for even more advanced temperature control for both heating and cooling phases.

Customers may also elect to include the Edge II Control System, a specialized recipe and data collection system programmed to monitor critical processing data, insuring consistent results. Press operators can create & store process recipes, retrieve and capture data with chart and display graphs on a color touchscreen interface. The system has an Ethernet communication port, allowing integration into the customer's plant system. Further, French's electrical engineers can remote into the permission-based control system to make electrical upgrades or for troubleshooting.

A mold cart with casters is available to allow easy tooling transport from the layup or tooling room to the press room. Guides are provided to insure proper alignment between the cart and the press. Low friction rollers or bearings allow the tooling to be manually loaded and unloaded between the cart and the press.

French provides technical assistance to re-assemble and start-up the press once it arrives at the customer's facility. In addition, the French technician facilitates basic operation training to help the customer start molding their critical components soon after delivery.

FASTSUITE - Focus on efficiency in Digital Factory

With two product lines, FASTSUITE for V5, which is seamlessly integrated with CATIA/DELMIA V5, and FASTSUITE Edition 2, a standalone platform, the areas of OLP (offline programming), manufacturing simulation and virtual commissioning are the core of our business activities. Our applications and solutions are not only focused on real customer needs, but they are also designed to improve efficiency and quality of our customers' manufacturing processes. No matter if the process is just about offline programming of a single robot at a small job-shop company or about the validation of a complete production line at an Automotive or Aerospace OEM. We strive to ensure a constant quality of our services and to provide the best possible support to our worldwide customers. Therefore we have established three digital manufacturing hubs around the world. All our teams have a proven expertise on manufacturing process integration and profound IT implementation skills.
