IMPAX | SK Technologies


IMPAX process monitors have held a strong position within the metal forming, stamping, and cutting industries for the past 20 years, with over 6000 successful installations. PTG is a market leader in the fastener industry in the United States, and also markets its monitoring expertise abroad. IMPAX process monitors use a patented algorithm to learn the correct force profile for a process, and then monitor that process. They make use of peak and area-under-curve analysis to provide robust consistency and machine protection.

PTG also offers products for efficiency and productivity monitoring, in the IMPAX Time Saver System. These monitors combine extensive data tracking with a user-friendly interface, to create a powerful machine efficiency and downtime tracking system. Time Saver monitors work as stand-alone units and are also networkable, forming a flexible and powerful production monitoring and downtime analysis system.

PTG also provides IMPAX/SK process monitors, via partnership with German monitoring company Schwer+Kopka GmbH. These monitors use a proprietary high-speed digital signal processor system, and provide advanced software features. These monitors are sold in the Americas under the IMPAX/SK Technologies label, and in Europe under the Schwer+Kopka label. The cooperative partnership of PTG and SK has been recognized for its innovative designs and technical excellence. From its inception, IMPAX/SK Technologies has brought to the market the unique ability to develop innovative turn-key solutions for a variety of metal forming, stamping, and cutting applications.

Benefits of Process Monitoring

IMPAX process monitors can significantly reduce setup and adjustment time for your machines, by letting operators know when a machine is running consistently within established parameters.

  • Reduce setup time
  • Reduce man-to-machine ratio
  • Reduce downtime troubleshooting time

Process monitors help machines run more productively. They alert operators of any problems so they can be fixed quickly. IMPAX monitors also let you run machines through breaks and ghost shifts.

  • Increase production time
  • Increase quality control
  • Increase machine efficiency
  • Reduce scrap
  • Eliminate overruns

Using IMPAX process monitors reduces the wear to machines. Since the monitors stop the machine when a fault is found, problems that could cause damage to tooling or dies are prevented, and bad parts are detected before they pass down the line and cause more problems. Process monitors can also detect gradual wear of tooling, telling you when to replace them so they don’t break while running.

  • Increase tool lifetime
  • Reduce tool wear
  • Reduce machine downtime
  • Eliminate machine smashups

IMPAX monitors can track production data by shift, by part, and by operator. This means that you will have complete information on orders and parts, and jobs will be ready faster and will have higher quality.

  • Reduce sorting costs
  • Reduce order contamination
  • Reduce customer returns, charge backs

Compact Process Monitoring Systems

The new process monitoring units of our series SK 200 to SK 800 offer unprecedented ease of operation and feature a completely re-designed touch screen operating surface. All models are equipped with our proven Puzzlemaster expert  routines and the advanced Mandonic auto enveloping technique as standard feature.

Superflex Sensors fit into an 8mm hole and can be manually adjusted to pick up the best signal. They can also be easily removed and replaced.

Diskflex sensors are significant less expensive than the Superflex sensors and are epoxied into areas for best signal pickup. They have been used in wedges, backing plates, feed stops, and even embedded into tool holders. Many sizes are available from 8.9mm to 50mm.

The X-flex sensor is a strain sensor and is usually attached to the frame of a machine to protect the machine from an overload condition. The surface strain (tension or compression) is directly related to machine load, for example, on presses.

Easy to install sensors are bolted onto machine parts which are taking the loads from the cutting process such as drive arms for longitudinal or cross slides. These sensors measure the cutting forces and/or the acoustic emission signals. Alternatively, electrical power sensors are registering the power consumption of the electrical drive motors.

Diskflex sensors are significanly less expensive than the Superflex sensors and are epoxied into areas for best signal pickup. They have been used in wedges, backing plates, stripper plates and even embedded into tool holders. Many sizes are available from 8.9mm to 50mm.

FOXMATIC MONITORING TECHNIQUE reacts to even the smallest changes in force signals. It works independently within envelope limits while its automatic drift compesation avoids undesired nuisance machine stops. It is applicable to cold formers and thread rollers and offers reliable fault detection for even the smallest errors (i.e. cracked heads). Foxmatic is the perfect complement to the proven Mandonic auto envelope technique.
