 Press Releases

  • Brighton, MI, October 22, 2019 – Promess, Inc. has introduced a new servo-based electro-mechanical actuator intended for applications requiring programmable rapid non-stop motion at frequencies not well suited for ballscrew-type presses.  The Bolt Actuator achieves this new level of performance through Promess’ Dual-Eccentric Servo technology.  This new innovation employs an eccentric shaft mounted inside an eccentric sleeve, both of which are independently servo controlled, to provide dynamic stroke-length and/or force/distance profile adjustment in real-time.

    The Bolt Actuator has an integral force sensor that measures reactive load in real-time.  Bolt is married with the Promess UltraPRO control system to form a complete package to handle applications such as fatique testing, long-term characterization of mechanical parts, high-speed assembly, metal forming, die compaction of powdered metals, and materials packaging.

    Promess will initially offer the BOLT in two configurations, each having a variable stroke length of 0 to 26 mm:  a 4kN model that operates from 0 to 8 Hz and a 1 kN model that extends to 30 Hz.  Future designs will easily scale up to more than 60 kN at motion frequencies up to 75 Hz.

    The Bolt Actuator is capable of 0.0005 mm resolution, 0.039 mm position accuracy and 0.005 mm repeatability. The Promess UltraPRO controller used in the Bolt system also can accept and integrate input from a broad range of external sensors including position transducers and load cells.

     “The Bolt fills a niche for a programmable servo press that can operate at relatively high frequencies while allowing the stroke to be dynamically adjusted for length, force, speed or any combination of the them,” explained Glenn Nausley, President. “It’s an ideal solution for applications like fatigue testing as well as assembly operations including pin insertion, stamping, capping, staking or plugging.

    “A ballscrew driven linear servo press requires the motor to stop and reverse direction at the beginning and end of every stroke; the time required to do that plus the associated accel/decel time limits the practical frequency it can achieve. Repetitive motion over a small range also concentrates wear to that portion of the ballscrew. The Bolt eliminates both of those issues.”

    The BOLT Actuator can adjust any combination of speed, force and distance “on the fly” within a single stroke based either on a pre-programmed profile or sensor feedback.  The software package included with the initial Bolt offering produces pure sinusoidal motion. Future versions will allow for a wider range of profiles, for example, rapid approach/slow press/rapid retract which can be useful in certain assembly operations.

    “The UltraPRO is easily integrated into existing data storage and analysis systems,” Glenn Nausley added. “That makes it simple to document test and/or assembly operations to provide traceability for individual products which is extremely important in applications like medical device manufacture.”

    Promess is a 35-year-old firm that develops, manufactures, and markets its family of sensing

    devices, electronics, assembly presses and test systems on a global basis.

  • Brighton, MI – October 24, 2018 – Promess Inc. introduced a new servo-controlled electromechanical platen-type press in Booth 1438 at Fabetch in Chicago, November 11-14. The Promess Platen Press is designed for assembly and material preparation applications in battery manufacturing, aerospace component production and similar areas requiring precise application of high force over a large area.

    The platen press uses multiple Promess Electro-Mechanical Assembly Presses (EMAPs) to move the platen and supply the specified force. They are controlled by a multi-axis Promess UltraPRO controller running proprietary software that enables “joined-axis” control of the EMAPs.

    The platen press being exhibited at Fabtech is an 80 kN (18,000 lbs-force) model with a 1.2 x 0.91 m (3’ x 4’) platen and 330mm (13in) stroke. It uses four Promess 20 kN (4,500 lbs-force) EMAPs and an UltraPRO controller running Promess Joined-Axis software. Other standard Platen Press configurations are available with up to 2,000 kN (400,000 lbs-force) with platen sizes varying depending on the specific application needs.

    Joined-axis control means the controller monitors both the force and position of each EMAP and makes adjustments in real-time to provide uniform downward motion and pressure during the entire press cycle.

    The Promess Joined-Axis Software allows the user to program the multiple EMAPs as a virtual single device eliminating the need to write individual control programs and an integrating algorithm. This greatly simplifies application programming for the platen press.

    “The platen press is a natural result of our experience with systems to press Lithium Ion battery electrolytes,” explained Promess president Glenn Nausley. “Achieving high energy density requires the powdered materials to be pressed to very tight tolerances for both density and dimension. We met the challenge for small batteries, like those used in pacemakers and other devices, with systems based on a single EMAP.

    “But, larger batteries, like those used in electric vehicles, need something with greater output than a single EMAP even using the largest available models,” Nausley continued. “The Platen Press using multiple EMAPs is the logical solution.

    “To make that work we needed a very capable control and some specialized software. Fortunately, both the UltraPRO and the joined axis software were ready when we needed them.

    “There are many other applications in other industries that could benefit from a precision press with a large working area,” Nausley said, “and the platen press is an ideal solution for them. We are actively pursuing opportunities in aerospace, automotive, packaging and a number of other areas.”
