Answers are written by the engineer who runs the work \u2014 not by marketing.<\/p>\n<div class=\"lw-faq\">\n<details>\n<summary>\n<p>Who actually does the QC on my machine?<\/p>\n<\/summary>\n<div class=\"lw-faq-a\">\n<p>A named Loway quality engineer owns the build record for your machine from drawing review to dispatch. The same engineer signs the pressure test report, joins the third-party pre-shipment inspection and answers your QA team&#8217;s email. If you want a specific person named in your order folder, tell us when you <a href=\"\/vi\/contact-us\/\">contact us<\/a>.<\/p>\n<\/div>\n<\/details>\n<details>\n<summary>\n<p>Can we witness the factory acceptance test (FAT) remotely?<\/p>\n<\/summary>\n<div class=\"lw-faq-a\">\n<p>Yes. A typical remote FAT is a live video walk-through of the hydraulic run-test, the product-specific test (water leak, vacuum-hold, torque or belt-tension) and the PLC dry-run, with the test plan emailed to you the day before. Customer on-site visits are also scheduled against the build calendar so nothing slips.<\/p>\n<\/div>\n<\/details>\n<details>\n<summary>\n<p>Do you accept third-party pre-shipment inspection (PSI)?<\/p>\n<\/summary>\n<div class=\"lw-faq-a\">\n<p>Yes. We regularly host SGS, BV, T\u00dcV, Intertek and customer-appointed inspectors. Send the test plan when you <a href=\"\/vi\/contact-us\/\">contact us<\/a> and the engineer will schedule it against the build calendar; the PSI report joins the QC document pack on dispatch.<\/p>\n<\/div>\n<\/details>\n<details>\n<summary>\n<p>What CE documentation do you provide?<\/p>\n<\/summary>\n<div class=\"lw-faq-a\">\n<p>For machines shipped into CE-marked jurisdictions, we provide a Declaration of Conformity and the relevant sections of the technical file (Machinery Directive, low-voltage and EMC where applicable). Documentation scope is confirmed per order based on destination and machine configuration.<\/p>\n<\/div>\n<\/details>\n<details>\n<summary>\n<p>Can we add our own inspection hold-points?<\/p>\n<\/summary>\n<div class=\"lw-faq-a\">\n<p>Yes. Customer hold-points are common at three stages \u2014 weld inspection before paint, FAT before packing, and a documentation review. Tell us your hold-points and timing when you <a href=\"\/vi\/contact-us\/\">contact us<\/a> and the engineer folds them into the build schedule before cutting starts.<\/p>\n<\/div>\n<\/details>\n<details>\n<summary>\n<p>Do you provide material certificates and NDT reports?<\/p>\n<\/summary>\n<div class=\"lw-faq-a\">\n<p>Yes. Mill certificates for steel plate and profiles, batch numbers for filter plates and cloths, and (where specified) Magnetic-Particle or Ultrasonic NDT reports on critical welds are filed by machine serial and go out with the QC document pack on shipment.<\/p>\n<\/div>\n<\/details>\n<details>\n<summary>\n<p>What happens if a machine fails its test?<\/p>\n<\/summary>\n<div class=\"lw-faq-a\">\n<p>The machine is held on the floor, the failure mode is recorded on the build record, and the engineer decides whether it is a repair, a rework or a replacement part. The buyer is informed by email before the machine is back on the schedule \u2014 not after. Failed machines do not leave the factory under a passed stamp.<\/p>\n<\/div>\n<\/details><\/div>\n<p>      <!-- 4 internal-link chips --><\/p>\n<nav class=\"lw-qc-related\" aria-label=\"Related resources\">\n        <a href=\"\/vi\/about\/company-factory\/\"><svg class=\"lw-ic\" viewbox=\"0 0 24 24\" aria-hidden=\"true\"><polyline points=\"9 18 15 12 9 6\"\/><\/svg>Inside the Loway factory<\/a><br \/>\n        <a href=\"\/vi\/about\/engineering-team\/\"><svg class=\"lw-ic\" viewbox=\"0 0 24 24\" aria-hidden=\"true\"><polyline points=\"9 18 15 12 9 6\"\/><\/svg>The engineering team<\/a><br \/>\n        <a href=\"\/vi\/engineering\/sludge-testing\/\"><svg class=\"lw-ic\" viewbox=\"0 0 24 24\" aria-hidden=\"true\"><polyline points=\"9 18 15 12 9 6\"\/><\/svg>Sludge testing &amp; bench test<\/a><br \/>\n        <a href=\"\/vi\/parts-service\/\"><svg class=\"lw-ic\" viewbox=\"0 0 24 24\" aria-hidden=\"true\"><polyline points=\"9 18 15 12 9 6\"\/><\/svg>Spare parts &amp; service<\/a><br \/>\n      <\/nav>\n<\/p><\/div>\n<\/section>\n<p>  <!-- ============ QC-CTA ============ --><\/p>\n<section class=\"lw-band lw-band--cta\">\n<div class=\"lw-container\">\n<p class=\"lw-kicker\" style=\"display:block\">Plan your quality gate before the build starts<\/p>\n<h2>Want a test plan, witness points or CE file?<\/h2>\n<p class=\"lw-band-sub\">Tell us your sludge, capacity and destination market \u2014 the quality engineer will come back with a sizing recommendation, a quotation and the QC document pack that matches the standards your procurement and QA teams need.
