Case Study: Sub-Zero achieves high-precision refrigerator quality control with Hexagon CALIPRI C14

Streamlined, high precision measurement of household refrigerators

Sub-Zero, a manufacturer of high-end refrigerators, needed to enhance its quality control process for ensuring precise gaps and flushes on its products. The company's manual gauges were time-consuming and posed a risk of scratching appliances. They partnered with Hexagon to implement its CALIPRI C14 non-contact portable measurement solution.

Hexagon's solution provided fast, accurate, and reliable non-contact measurements, eliminating the risk of surface damage. This allowed Sub-Zero to perform 100% inspection at final assembly, implement a tighter tolerance scheme, and give operators immediate pass/fail results. The change increased overall product quality and reliability, with tests showing the device achieved a high level of consistency between different operators.
