Defect Tracking Solution

  • Catching defects through process monitoring in real time
  • Operator error proofing
  • Reducing the overall scrap generated during manufacturing
  • Predictive defect reduction
  • Real time validation of product routing within the manufacturing process
  • Defect root cause analysis
  • Provides the ability to automatically ensure only the right products are being processed for the defined manufacturing process
  • Provides the ability to increase yield and reduce scrap by enabling products to be reworked at the point of failure
  • Provides the ability to track defects by process and material providing the ability to identify problem areas in manufacturing
  • Eliminates assembly errors by assuring correct setup and that production routes are enforced
  • Provides details on the type of defect and the point of failure driving to identifying areas where defects occur

Overview
Discrete manufacturers are faced with the difficulty of tracking defects and change requests within a complex product. Defects are often logged against the whole product though they apply to a particular sub component that requires rework. Tracking defects and resolving these issues without a capable system leaves room for process failure, lower yield and higher scrap. Traditional factory automation systems can only track productions by the lot which might contain thousands of identical items which cannot be identified individually - leading to defects being tracked by lot and not by individual items.

Solution
KeyTone's defect tracking solution captures defect data of every product, by station, by time of process deviation. The availability of this information in real time empowers line supervisors and factory managers to rework defects at the point of occurrence considerably increasing first pass yield and quality. For discrete manufacturers the KeyTone solution not only supports best practices in production but also in test, repair and non-conformance handling. 

KeyTone's solution offers the enterprise to: 

  • Identify where the most common defects occur to enable process change that will reduce defects 
  • Identify the source of defects to be able to determine the root cause of the defects be it part of the manufacturing process - human resource or environment 
  • Quarantine defective parts at the point of failure to prevent defective parts from continuing through the production line 
  • Automatically notify process owners when a defect is detected to enable real time decision making at the process level
