The quality control process looks at the height and width of the tape that is produced in the upstream process as any deviation from production standards could result in a product which is unable to deliver adequate sealing when it is used by customers. This would potentially lead to unwanted moisture ingress within the application of the product which could then lead to damage to the structures and products where the tape has been applied. Excessive height of the tape may also, in low tolerance applications, cause uneven pressure on the joint where it is used, leading to early product or structural failure.
Data from this process is recorded within the SPCWorks database. When the software identifies a problem with the tape which falls outside the acceptable parameters the machine is automatically stopped.
Key information provided by the software includes Process Statistics (Cp, Cpk, Pp, Ppk) which also provide complete visibility of the upstream production process, enabling our client to take preventative measures before a defect occurs, and where there are problems the tape can be removed from the production line.
These new processes ensure that no defective tape is packaged or sold to the end consumer resulting in no in-operation product defects.
