Greenerd Press & Machine Company, Inc. recently completed construction of a new "Engineered to Fit" 75-ton hydraulic forming press for a medical device manufacturer. The Greenerd press features an advanced design that provides the manufacturer with greater control and a more streamlined production process.
The press, which has helped to reduce expensive scrap, was specifically engineered for a forming process producing Titanium blanks to a critical final specification. The new 75-ton Greenerd press features a 35-ton cushion cylinder that is also used as a knockout. A secondary ram mounted 20-ton cushion / eject has proportionally controlled speed for the eject function.
The Greenerd press provides hydraulic clamping for a quick change-over of tooling, plus RFID identification of tooling to prevent the use of incorrect tool sets and / or tool program mismatch, streamlining the production process. Closed-loop control of the tooling heaters, using a Watlow temp controller, facilitates each part being drawn at the same 600 degree Fahrenheit temperature within a tolerance of +/- one degree.
The press is capable of multiple dwell positions and times during each cycle, and also features extremely slow closed-loop processing speed control for drawing super tough alloys, such as Titanium. The main RAM has two pressing circuits, offering a fast press configuration that is adjustable from 7.2 IPM to 36 IPM and a slow press set-up that is adjustable from 0.2 IPM to 2.0 IPM.
"Greenerd's state-of-the-art controls feature a robust press touch screen that integrates all press and tool controls, including process trending and trouble-shooting feedback. In addition, the integral cushion with distance and pressure control / feedback provides unparalleled flexibility and control," said a company spokesperson.
"Learning about our customer's business, applications and objectives allowed us to design and build a press that is best suited for the customer's needs and allows them to achieve their goals," said Greenerd Press & Machine Company President, Tim Dining.
