Hull Industries can build hydraulic compression presses from 10 tons up to 4,000 tons. Our compression molding presses are used to mold a wide variety of both thermoplastic and thermoset composite and plastic materials. Based on the needs of your application Hull can design a relatively simple press or a high-speed press with a very complex control system.
Our Compression Press features include, but are not limited to the following:
- Energy Saving Electric Servo Motor driven hydraulics
- Heating/Cooling Platens with accurate multi-zone heat control up to 1000⁰ F
- Complete press systems for thermoplastic composites applications
- Automation including Caul sheet handling
- PC based HMI with Data Collection
- Network capabilities
- Active Parallelism Control
- Vacuum Press
- Very fast Clamp speeds
- Very accurate slow pressing speeds
- Multiple Daylights
- Multiple Axis Clamping
- Other features and options upon request
PRECISE CYCLE CONTROL ASSURES HIGH YIELD, CONSISTENT QUALITY
A PLC based control system allows easy setup of custom cycles. Auto Position Set buttons, allow for quick mold setup, and once mold parameters are set, they can be easily reloaded with the touch of a button.
To protect expensive molds, high-speed closing cuts off near the end of the stroke, and the clamp switches to slow speed closing.
Ideally suited for rubber, plastic, laminates and composites.
Standard Controls include PID temperature controllers, built into the PLC, and accessible through the touch screen interface. These controllers provide accurate temperature control of multiple heat zones.
Free-standing and console designs are available.
SUPERIOR DESIGN AND CONSTRUCTION FOR DURABILITY AND RELIABLE PERFORMANCE
C Series presses feature the heavy-duty construction and high-quality materials characteristic of all Hull Industries products. Features include chrome plated tie rods and heavy duty platens that prevent defection to assure precise molding to close-tolerance requirements. Special design features include a soft-close clamping mechanism that automatically changes clamp speed at a variable pre-set position and closes under low hydraulic pressure. Soft clamping protects your investment in expensive mold and loading fixtures.
Proportional pressure and speed control are available.
INTEGRATE YOUR MOLDING OPERATIONS WITH COMPATIBLE AUXILIARY EQUIPMENT
