      <p>Standardization of ejector pins saves time and money in mold maintenance. Here is a comparison of four commonly used standards.</p>

      <p><strong>JIS (Japanese Industrial Standard)</strong></p>
      <ul>
      <li>Core pin diameters: 1.0-20.0mm</li>
      <li>Head style: 90 degree countersunk or flat</li>
      <li>Tolerance: m6 (shank)</li>
      <li>Common in: Japanese and Asian mold shops</li>
      </ul>

      <p><strong>DIN/ISO 6751 (European Standard)</strong></p>
      <ul>
      <li>Core pin diameters: 1.0-25.0mm</li>
      <li>Head style: Flat with 15 degree chamfer</li>
      <li>Tolerance: f7 or m6</li>
      <li>Common in: European mold builders</li>
      </ul>

      <p><strong>HASCO (German Standard)</strong></p>
      <ul>
      <li>Core pin diameters: 1.0-32.0mm</li>
      <li>Lengths: 100-630mm</li>
      <li>Material: HSS, nitrided 1.2343, or through-hardened</li>
      <li>Common in: European and growing Asian markets</li>
      </ul>

      <p><strong>DME (North American Standard)</strong></p>
      <ul>
      <li>Core pin diameters: 1/32 to 1 inch (imperial)</li>
      <li>Material: H-13, M-2 HSS</li>
      <li>Common in: US and Canada</li>
      <li>Note: Imperial sizes are not directly interchangeable with metric</li>
      </ul>

      <p><strong>Practical tip</strong>: If you export molds, specify pin standards upfront. A mold built to HASCO standards is serviceable in Europe immediately. A DME mold requires DME-stocked spares.</p>

      <p>Cross-reference charts are available from most pin suppliers.</p>
