We can ensure that all supplied products conform to all specified requirements through our state-of-the-art inspection facility. Customer complaints are rare, however if one occurs our inspection department delivers the resources to quickly analyze and resolve the situation. J Royal’s primary inspection tools include:

  • Micro-Vu Non-contact Visual Inspection Devices: Our Micro-Vu measurement systems are J Royal’s main inspection tools. They are highly sophisticated, computerized machines that can automatically measure parts against industry standards or the customer’s prints or drawings. Micro-Vu has an advantage over an optical comparator in that it can take measurements in the Z-axis (vertically). This accommodates dimensional measurements that normally would need to be taken on sectioned samples. Also, given the 3D nature of the Micro-Vu measurement system, we can measure distance, angle, diameter, radius, circularity, flatness, concentricity, parallelism, sphericity, true position, plus many more GD&T features.   
  • Density: We measure the specific gravity of incoming products through the Archimedes process. This enables us to quickly verify the compound type because the most common elastomers have a wide enough density range to allow identification through the specific gravity method. 
  • Shore A & M durometers: One of the most important physical properties of rubber materials is hardness. J Royal is equipped to measure incoming product on either Shore scale which helps us ensure that incoming parts meet customer hardness specifications. Typically, J Royal measures incoming shipments with the Shore A probe, though smaller parts often require durometer readings with the Shore M probe. 
  • Full Equipment List:
  • Two 12”x12”x6” Micro-Vu Units
  • Rex Shore M probe
  • Rex Shore A probe 
  • Analytical Lab Balance for reading specific gravity 
  • Surface Roughness Probe
  • Set of Pin Gauges (.061 to .750) 
  • Calipers (multiple sizes)
  • Snap Gauges (multiple) 
  • Micrometers (including an interchangeable tip micrometer) 
  • Digital Height Gauge with granite measuring block 
  • PI Tapes for large diameter parts

Note that J Royal maintains complete calibration records with all our inspection equipment. Also, we demand that every QC equipment calibration service provider is ISO/IEC 17025 certified.
