How defects get caught early.
Incoming material verification
Wire, sheet and purchased mesh are checked against the purchase order for alloy grade, lot traceability and supplier mill test certificates when ordered. On arrival we sample mesh count and wire diameter against the specification using mesh-count screens and measuring tools — values are not assumed from the supplier label alone. Stainless grades are visually checked for surface condition, edge damage and packaging integrity before release to cutting, weaving or fabrication. Nonconforming incoming material is quarantined and replaced or rejected before it enters production; sampling level and certificate scope follow what is agreed on the PO.
In-process control at hold points
Cutting, edging, welding, forming and assembly are checked against the customer drawing at defined hold points — blank dimensions before welding, seam alignment on cylinders, layer registration on multilayer packs and handle or flange fit on strainer baskets. Operators perform visual checks for burrs, weld continuity, contamination and mesh damage; critical dimensions are measured with digital calipers and recorded when the PO requires dimensional data. When a dimension is at risk of drift or a weld defect is found, production stops for engineering review rather than continuing batch buildup. Rework or scrap is documented according to the order scope.
Outgoing inspection before shipment
Before packing, finished parts receive outgoing verification aligned to the PO: dimensional checks on OD, ID, length and thickness where applicable, mesh count confirmation on filter media, visual inspection of welds, edges and cleanliness, and functional fit checks when gauges or reference samples are supplied. Inspection results are summarized in a report when ordered; packing photos showing product condition, labeling and crate preparation can be shared before shipment on request. Release to ship occurs only after agreed checks are complete. Certificate of conformity and export documents are prepared when specified — see the Certificates page for document types.
Inspection tools and typical records
Routine capability includes mesh-count verification, digital caliper dimensional measurement, visual weld and assembly inspection, and outgoing packing checks with photos. We do not claim test methods or equipment that are not part of your agreed order scope — specialized tests such as pressure decay, microscopy or third-party witnessing are quoted only when defined on the RFQ. Typical records include dimensional notes, inspection summaries, MTC when ordered and shipment photos; EN 10204 3.1 material certificates and third-party inspection (SGS/BV) cooperation are available on project orders when noted on the quote.
