F.A.S.T. tool chan­ging system

With the deve­lo­p­ment of the OPP elec­tric multi-plate pow­der press family, we sup­port our cus­to­mers in sol­ving their chal­lenges. Whe­ther it is cost, per­for­mance, qua­lity and pro­cess — die change and set-up, sta­ble pro­duc­tion pro­cess, pre­ven­tion of green com­pact crack­ing, part tracea­bi­lity -, con­nec­ti­vity, ser­vice, stan­dar­diza­tion and health & ser­vice, the OPP con­cept deli­vers con­vin­cing solutions.

The OPP family includes the ton­nage range 200t, 350t as well as 500t. With up to 4/4 axis con­cept as well as the revo­lu­tio­nary F.A.S.T. tool change solu­tion, even the most com­plex parts can be pro­du­ced with pre­cis­ion and repea­ta­bi­lity. Due to the con­trol con­cept, even heli­cal parts can be pres­sed easily and wit­hout an addi­tio­nal invest­ments. Our cus­to­mers achieve excep­tio­nally good Cm(K) values with their OPPs, which meet or exceed the high requi­re­ments in the auto­mo­tive sec­tor in particular.

More good parts at a lower total cost

The advan­ta­ges of the OPP con­cept com­pared to cur­rent hydrau­lic con­cepts are intrinsic:

Increased pro­duc­ti­vity and ope­ra­tio­nal effi­ci­ency through

  • Bet­ter con­trol and hig­her sus­tainable speed
  • hig­her pre­cis­ion, posi­tio­ning accu­racy ±1 to ±2 µm
  • hig­her repea­ta­bi­lity ±1 to ±2 µm
  • machine-aided pro­gramming and pro­duc­tion con­trol — imPRES­Sive MP HMI
  • hig­her OEE +18%
  • “on the fly chan­ges” wit­hout stop­ping the machine
  • No hea­ting up to ope­ra­ting temperature

Lower total cost of owner­ship and ope­ra­ting costs due to

  • lower energy con­sump­tion ‑50% to ‑80%
  • less main­ten­ance ‑60% to ‑80%
  • Over­all low invest­ment in the system
  • Eli­mi­na­tion of the exter­nal adap­ter and its expen­sive infrastructure
  • Infra­struc­ture savings
  • Heat and noise emissions

  • 70 % less CO2 over the entire life cycle

When it comes to high pres­sing forces com­bi­ned with high pre­cis­ion, you will find it hard to get around Oster­wal­der pow­der pres­ses. We offer elec­tric, hydrau­lic and hybrid pres­ses of excel­lent qua­lity com­bi­ned with the hig­hest performance.

The first and only elec­tric 2000 kN Multi-plate pow­der press

The OPP 2000 is the forerun­ner of a pro­duct family with press forces bet­ween 1,000 and 5,000 kN. Until now, pres­ses for such high forces were only available with hydrau­lic or mecha­ni­cal drives.

The OPP 2000 thus sets a new bench­mark for ope­ra­tio­nal efficiency:

Energy con­sump­tion savings 
80%
Avai­la­bi­lity — ther­eby pro­duc­ti­vity control 
98%
  • Opti­mi­zed Net-Shape per­for­mance, which eli­mi­na­tes the need for secon­dary post-processing
  • Infra­struc­ture savings — no pit required
  • Eli­mi­na­tion of the exter­nal adap­ter and its expen­sive infrastructure
  • Hig­her avai­la­bi­lity due to reduc­tion of maintenance

Hydrau­lic dri­ves also have tech­ni­cal dis­ad­van­ta­ges, inclu­ding some­ti­mes long start-up times and fluc­tua­tions in press ope­ra­tion, which impair avai­la­bi­lity but also pro­cess accu­racy and repeatability.

F.A.S.T. on board!

The OPP 2000 is equip­ped with the patent-pen­ding moun­ting sys­tem for tools (F.A.S.T.) which allows an unpre­ce­den­ted fast exch­ange of dies. The multi-levels always remain instal­led in the press, while the dies are held in inter­ch­an­geable fix­tures that are very com­pact and can be trans­por­ted and stored in a rack. The dies are thus always at hand for chan­ges in production.

Due to a novel archi­tec­ture of the gui­des, high pres­sing forces can be applied to each indi­vi­dual axis. While pre­vious elec­tric pres­ses offer a limi­ted coun­ter­force, the OPP 2000 allows maxi­mum pres­sing force to be applied to both the top and bot­tom pla­tes of the press. The motor wedge sys­tem also offers a large adjus­t­ment option that maxi­mi­zes flexibility.

A large hydrau­lic sys­tem also has a signi­fi­cantly hig­her aging rate com­pared to elec­tri­cal com­pon­ents, which leads to leaks that con­ta­mi­nate the die space and the press parts.

Swit­ching to an elec­tric drive impro­ves the pre­cis­ion, repea­ta­bi­lity and accu­racy of your pro­duc­tion pro­cess and allows you to meet your requi­re­ments for more com­plex geo­me­tries and “net-shape”.
