Ensure quality standards with poka-yoke checks
Typical error sources include missing or incorrect parts, insufficient evaluation of colors, a defective assembly process or even manual data entries and machine configurations.
Further problem areas
Threads are a frequent production problem. Missing or incomplete threads can occur in screw, bolts and threaded holes.
It is also very difficult to find the right screw for a certain torque, as well as the tightening sequence. Electrical torque controls are a step in the right direction, but cannot prevent problems. The positioning of torque tools has proven successful.
Errors can also occur wherever markings or labels are made manually. Such errors can be avoided with a simple traceability system.
When it comes to error prevention: Every production step done by hand can lead to an error. This includes all assembly procedures and machine configurations. In these areas, an evaluation must be carried out to ensure that suitable quality standards, such as those of Total Quality Management (TQM), are met. In general, at least two poka-yoke checks should be made for each assembly procedure.
