If a customer receives EVA 1.5mm<\/strong> material but measures around 1.2mm<\/strong>, is it a product defect\u2014or a measurement tool\/method<\/strong> issue? This case study shows how we closed the loop with standardized re-testing, clear explanations, and photo\/video evidence<\/strong>, avoiding unnecessary returns and claims.<\/h3>\n

Background<\/h3>\n

A customer from Argentina<\/strong> placed an order for 1.5mm EVA material<\/strong>, total quantity 10,000 meters<\/strong>. After receiving the shipment, the customer measured the thickness using their own gauge and reported readings around 1.2mm<\/strong>, which raised a serious concern about compliance with the agreed specification.<\/p>\n

Customer Concerns<\/h3>\n
    \n
  • \n

    Fear of non-conforming goods<\/strong>: A 1.2mm reading could impact downstream processing and product performance.<\/p>\n<\/li>\n

  • \n

    Conflicting measurement results<\/strong>: Different readings created uncertainty, extra communication cost, and potential production delays.<\/p>\n<\/li>\n

  • \n

    Need for reliable evidence<\/strong>: The customer required a clear, repeatable measurement process\u2014not just verbal reassurance.\"\"<\/p>\n<\/li>\n<\/ul>\n

    Our Immediate After-Sales Response (SOP)<\/h3>\n

    Once we received the feedback, we activated our internal after-sales process and closed the loop in three steps:<\/p>\n

      \n
    1. \n

      Sampling & measurement-condition verification<\/strong>
      We checked retained bulk samples and clarified the customer\u2019s measurement method (pressure, probe type, position, timing, and material compression behavior).<\/p>\n<\/li>\n

    2. \n

      Re-testing with a dedicated EVA thickness gauge<\/strong>
      EVA is elastic and compressible. If a gauge is not suitable (insufficient precision, inconsistent pressure, or mismatched probe structure), readings can deviate significantly.
      Using our professional EVA thickness measuring instrument<\/strong>, we re-tested bulk samples from the same production batch and confirmed:<\/p>\n

        \n
      • \n

        Thickness was consistently above 1.5mm<\/strong><\/p>\n<\/li>\n

      • \n

        Results were stable and aligned with the order specification<\/p>\n<\/li>\n<\/ul>\n<\/li>\n

      • \n

        Visual proof + clear explanation<\/strong>
        We documented the entire re-test procedure with photos and videos<\/strong> (including gauge readings, step-by-step testing, and sample positions). We explained that:<\/p>\n

          \n
        • \n

          The customer\u2019s gauge had precision and suitability limitations<\/strong><\/p>\n<\/li>\n

        • \n

          EVA requires a proper testing setup<\/strong>, otherwise compression can lead to lower apparent thickness readings\"\"<\/strong><\/p>\n<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n

          Outcome<\/h3>\n
            \n
          • \n

            After reviewing our photo\/video evidence, the customer agreed the issue was caused by measurement-tool limitations and method differences<\/strong>, not by product quality.<\/p>\n<\/li>\n

          • \n

            The concern was resolved smoothly, preventing unnecessary returns or claims and supporting continued cooperation.<\/p>\n<\/li>\n<\/ul>\n

            What We Standardized from This Case<\/h3>\n

            To reduce similar disputes, we now proactively support customers with:<\/p>\n

              \n
            • \n

              Recommended measurement guidelines<\/strong> (pressure\/probe, sampling positions, repetitions, recording template)<\/p>\n<\/li>\n

            • \n

              Third-party verification support<\/strong> when required<\/p>\n<\/li>\n

            • \n

              Batch sample retention & traceability<\/strong> for fast re-checking<\/p>\n<\/li>\n

            • \n

              Customizable specifications<\/strong> for thickness, width, and performance as needed<\/p>\n<\/li>\n<\/ul>\n

              Why Ningbo Dolphins<\/h3>\n

              We work closely with Latin American clients and understand what matters most: stable quality, reliable delivery, and fast after-sales support<\/strong>. When data conflicts happen, we solve them with standardized testing and visual evidence<\/strong>, so customers can use materials with confidence.<\/p>\n
