Vertel ons welk apparaat beschadigd is en beschrijf de symptomen, foutcodes of machineproblemen.
Stuur de beschadigde PLC, CNC-module, HMI-paneel, frequentieregelaar, servomotor of voeding naar Koster Industrial.
We inspecteren het apparaat, verifiëren de storing en stellen een duidelijke reparatieofferte op.
Na goedkeuring repareren we het apparaat op componentniveau en testen het onder bedrijfsomstandigheden.
Na succesvol testen verpakken we het apparaat veilig en verzenden het per koerier terug.
Ons reparatieproces begint met een gedetailleerde beoordeling van de storing. Wij onderzoeken de voedings-, besturings- en vermogensmodules (inclusief IGBTs, MOSFETs en thyristoren) evenals de meet-, koels- en communicatiesystemen. Spanningscontroles en elektronische componenttests worden uitgevoerd.
Industriële apparatuur wordt vaak blootgesteld aan zware vervuiling. Elke assembly wordt grondig gereinigd in een ultrasone bad en gedroogd in gespecialiseerde apparatuur.
We restore or replace damaged parts such as power modules, supplies, I/O sections, communication interfaces, and cooling or measurement systems. We also proactively renew the most failure-prone and short-lived components to secure years of trouble-free operation. PCBs are refurbished, and all THT and SMD electrolytic capacitors are always replaced.
Once repairs are complete, we test each unit on dedicated benches through several stages:
Stage I – safe-mode testing (galvanic isolation, limited supply power) using our proprietary "bulb testers."
Stage II – load testing
Conducted on a dedicated rig built around a CU 320 control unit. The stand is paired with a dynamometer that lets us load the device under test with up to 15 kW, enabling thorough checks of power supplies, drive modules and servomotors.
Stage III – integration testing with native Siemens CNC systems
We use a Sinumerik 840 D SL test bench to evaluate drive modules, Combi modules, operator panels with TCUs and MCP machine keyboards. The core test runs a CNC program in automatic mode for a minimum of four hours.
Stage IV (optional) – thermal-stress testing
Units are cycled at reduced temperature (≈ 0 °C) and then heated to 50 °C in an industrial oven. This procedure is reserved for elusive faults that appear only once every few hours—or even days—under normal conditions.
