Top On-Site Tests for Watches
Top On-Site Tests for Watches In the watch industry, quality is paramount and Vositone, as an expert manufacturer, maintains a high standard of quality assurance (QA) processes from pre-production to post-production. There are three phases involved in our watch manufacturing quality control protocol: Incoming Quality Control (IQC) To ensure the quality of essential components, we employ rigorous testing that focuses primarily on a watch's main parts – dial, case, and strap. DialsDials are tested for ultraviolet (UV) resistance (UV Rays Test). This is done by applying an alloy paper over the dial in a half-covered position before placing it under the light of a UV machine. This determines if any dials show discoloration within 72 hours. CasesAn Abrasion Test determines cases’ resistance to scratches. The usual process involves tumbling the cases in a coarse mixture of materials that can cause abrasion. This test checks for corrosion and scratches to the metals. A separate Cases Condensation Test follows to examine if the cases meet waterproof standards by heating up the cases before placing them on cold plates and checking for any internal condensation. StrapsA common test for straps is the Tension and Torsion Test. Here, the leather straps are continuously folded, stretched, and twisted using two different machines. Metal bracelets are checked using a separate machine where the cuffs are repeatedly shaken (also known as the Swing Test). All tests check the flexibility of leather straps and the sturdiness of metal bracelets. In-Process Quality Control (IPQC)During manufacturing, a series of follow-up tests are added in the process to guarantee quality. As a smartwatch manufacturer, for instance, the Hands Test confirms whether the watch’s hands are in the proper parallel alignment by careful examination using an HD monitor. Outgoing Quality Control (OQA)Before the final packaging and shipping, all watches are subjected to final inspection....
