Gasbarre Products, Inc. manufactures and designs capital and auxiliary equipment for the powder compaction industry, as well as full rebuild services.

■ Standard Series Presses

The Gasbarre Standard Series Press features an economical design providing the capability to compact a wide range of parts - single level, two level, or even multiple level depending on tooling design and options used.

■ Die Set Series Presses

The Gasbarre Die Set Series Press offers a readily removable die set. All necessary press adjustments are "built-in" to each press and are infinitely adjustable throughout their given range, allowing for simplicity in die set and tool design. This press series includes the die set and can be purchased with either a single lower punch die or a two punch die set.

■ Performance Series Presses

Precision guidance, extended guarding and synchronized density rod adjustments all say "performance". Guidance of the upper motion is achieved through the crosshead design. Precision ground Danly bushing on the upper and lower punch guidance, located very close to the die surface virtually eliminates transverse motion. Hardened and precision ground surfaces provide durability and reliability even in the presence of abrasive powders. The result is minimal tool wear, consistent press motion, and part-to-part repeatability. One lower punch plus shelf-in-the-die, a core rod that takes 50% of pressing tonnage, and two upper punches provides the flexibility of simple-to-complex parts manufacturing. Precise density splits are achieved through the die table float.

Fill, ejection and upper punch positions are worm gear driven and control powder transfer. These can be motorized to save time and setup steps. Modular guarding provides physical barriers for operator safety, spacious enclosures for mounted hardware, easy access and maintenance. Lexan guards at the point-of-operation allow continuous inspection of the compacting process.

Many options are available, including Top Punch Hold Down to protect delicate or thin parts during ejection, dual upper punch system for more complex parts, and upfloat/downfloat core rod with spring or timed release reduce ejection stresses. An automatic greasing system can be added to deliver metered amounts of lubricant at programmed intervals, and computer control of the press can be achieved with Gasbarre’s Presslog controller. Ask about other options now available.

■ Multi-Action Series Presses

The Gasbarre Multi-Action Series Mechanical Powder Compacting Press is unique in design utilizing state of the art technology for compacting complex, multilevel structural parts. This exclusive system offers both selective molding and ejection of the die platen and the #1 and #2 punch platens - eliminating the need for expensive bridging of tooling members. This allows greater tonnage to be placed in each punch due to decreased deflection. The #3 punch platen floats with a fixed molded position.

■ Sizing/Coining Presses

Gasbarre Products Inc. offers two styles of sizing presses to meet the needs of a wide range of parts. Inclined Automatic Sizing Presses and Upright Automatic Sizing Presses.

Gasbarre Hydraulic Compacting Presses are manufactured from 15 to 1200 tons for compacting single or multi-level parts for carbides, ceramics, plastics, powdered metals, and other particulate materials. Gasbarre Hydraulic Press designs offer opposed ram, withdrawal (plate float) or the combination.

New, state-of-the-art CNC Closed Loop Systems utilizing hydraulic servo-controllers, encoders, load cells, and touch-screen monitor provides superior press positioning accuracy, speed control, recipe memory setup, and repeatability to ensure consistent, high-quality production.

REMANUFACTURING & REBUILDING SERVICES
Gasbarre Hydraulic Press offers a complete range of services for Gasbarre presses, as well as those produced by other manufacturers.

Remanufacturing | Our thorough remanufacturing process reuses only the frame and die set, adding state-of-the-art computers and electronic hydraulic systems to provide reliability, precision, self-diagnostics, and rapid setup.

Rebuilding | Our rebuild team can disassemble and clean your press unit, evaluate wear surfaces, check for structural damage, remanufacture components, and fit them to the press.

Both processes are followed by a thorough, quality check to ensure that the machine performs to your specifications.

We also offer upgrades and retrofits to add capability, increase reliability, improve overall controls, extend guarding, or make setup easier. Rebuild, upgrade, and retrofit services are completed quickly to return your press to productive service as soon as possible.

The Gasbarre Servo-Electric Press is available for precise compaction of powder into a wide variety of geometries. The technology utilized includes high-efficiency and high-precision servo drives to control the motion of the upper ram, die plate, and automatic die filling systems. Each axis of the press is freely programmable for complete control of the compaction cycle: die filling, upper punch motion/compaction, die motion, and ejection cycle. Movement of the press axes are performed by closed-loop control. This means that extreme precision and repeatability are the result. This high-precision affords for consistent production of compacted powder components

PTX-Pentronix, a division of Gasbarre Products, Inc. is located in Plymouth, Michigan, USA. They are designers and manufacturers of a complete line of high speed and high precision powder compacting presses, robotic parts loaders and other products for the powder compacting industry.

Please click here to visit www.ptx.com for more information on their line of equipment, including:

Anvil-type Presses
Anvil pressing allows for high speed compacting of parts with one flat side. The other side can be flat or multilevel. The part can be thick or thin, have holes, teeth, etc.

Opposed Ram Type Presses

3-Mode Presses
The 3-Mode concept merges the anvil press design, the conventional upper/lower opposed-punch, and the double action press into one unit.

Loaders
Automatic, high-speed robotic parts handling systems that transfer parts from press to trays.

Located in Rugby England, SIMAC Ltd. also serves as the sales and service center for all Gasbarre Products, Inc. product lines for the European market.

SIMAC produces two types of isostatic presses:

Densomatic
presses are high speed, automatic, multi-cavity machines capable of producing a wide range of components. Spark plug insulators, oxygen sensors and grinding media are typical applications for the Densomatic press. In-line profile grinders and automatic loaders are available to be added to improve production efficiency.

Monostatic
press line is a single-cavity design that is suitable for research and development as well as production needs. Automation systems and in line horizontal lathes are available to be added to Monostatic presses.
