Krok 1: Ov\u011b\u0159en\u00ed materi\u00e1lu<\/h3>\n

Prvn\u00edm krokem je kontrola vstupn\u00ed hlin\u00edkov\u00e9 slitiny. Pokud z\u00e1kazn\u00edk po\u017eadoval slitinu 6063-T5 a \u0161ar\u017ee byla vyrobena ze slitiny 6005, mechanick\u00e9 a tepeln\u00e9 vlastnosti nebudou odpov\u00eddat.

P\u0159ed hromadnou v\u00fdrobou provedeme kompletn\u00ed m\u011b\u0159en\u00ed vzorku.

Tento krok n\u00e1m poskytuje referen\u010dn\u00ed bod pro zbytek v\u00fdroby.<\/p>\n

Krok 3: Kontroly v pr\u016fb\u011bhu procesu<\/h3>\n

Na povrchu kontrolujeme, zda nejsou \u0161kr\u00e1bance, probl\u00e9my s barvou eloxov\u00e1n\u00ed nebo jak\u00e9koli zn\u00e1mky ot\u0159ep\u016f.<\/p>\n

Krok 4: Z\u00e1v\u011bre\u010dn\u00e1 kontrola<\/h3>\n

P\u0159ed zabalen\u00edm kontrolujeme vybran\u00e9 vzorky nebo i 100% objedn\u00e1vky v z\u00e1vislosti na po\u017eadavc\u00edch z\u00e1kazn\u00edka.
