    {
      "q": "How do I specify a perforated plate correctly?",
      "a": "Give us hole shape and size, pitch and pattern angle, plate thickness, material and the margins (unperforated borders). If you only know the process duty, send that instead; we calculate open area and strength for you."
    },
    {
      "q": "Can you match an existing worn plate?",
      "a": "Yes. Send a sample or photo with key measurements and we reverse-engineer the pattern, usually improving the margin layout to extend service life."
    },
    {
      "q": "What open area do 3 mm holes on a 5 mm pitch give?",
      "a": "For round holes in a 60° staggered pattern: s = 0.906·(d/a)², so 0.906 × (3/5)² ≈ 33%. The same formula scales to any diameter/pitch pair, which is why we publish it: you can check throughput before you ask us to check strength."
    },
    {
      "q": "How small can holes be relative to plate thickness?",
      "a": "For punching, the working rule is hole diameter ≥ plate thickness; below that, tooling wear and burrs take over. If the process really needs finer openings than the plate allows, a woven or sintered layer on a coarser perforated support is usually the economical answer."
    },
    {
      "q": "Do you supply complete centrifuge baskets or only plate?",
      "a": "Both. Plate is cut, rolled, welded and assembled in-house, and centrifuge baskets and basket retrofits are typical work. Send the machine type and basket drawing, or the worn basket itself, and we quote the finished component."
