De rustfrit stål-dele, vi bearbejder, dækker fittings til fødevarekontakt, marinebeslag, komponenter i medicinsk stil og industrielt udstyr: 303 til letbearbejdelige fittings, 304 til generel korrosionsbestandighed, 316L til klorid- og marinmiljøer, 17-4PH hvor styrke betyder noget.
Korrekt kvalitetsvalg, værktøjsbaner og passivering er det, der får rustfrit stål til at præstere i drift — vi påpeger korrosionsrelevante angivelser under DFM-gennemgangen.

Tolerancer
ISO 2768-m standard; ±0,01 mm på kritiske detaljer.
| Tegningsangivelse | Hvad den kræver | Effekt på pris og leveringstid |
|---|---|---|
| Generel: ±0,25 mm / ±0,010 in | Standardværktøj, målingskontrol | Basisniveau: intet tillæg |
| Standard: ±0,13 mm / ±0,005 in | Maskine i god stand, førstestykkekontrol | Lille tillæg; det sædvanlige tilbudsgrundlag |
| Snæver: ±0,025 mm / ±0,001 in | Slebet eller diamantværktøj, temperaturstyring, CMM | Trinskift: langsommere skær plus fuld kontrol |
| Præcision: ±0,013 mm / ±0,0005 in | Finskær, grænsemål, kontrolleret miljø | Bearbejdningen dominerer prisen; ofte en separat operation |
| Position / vinklighed (GD&T) | Datumstyring, én opspænding hvor detaljer hænger sammen | Afhænger af, hvor mange opspændinger datumet spænder over |
| Overfladeruhed Ra 0,8 µm eller finere | Finere toothed fremføring, polering eller finskæring | Tilføjer et processtrin, ikke blot bearbejdningstid |

Ofte stillede spørgsmål
Hvilken rustfri kvalitet til et marint miljø?
316L er standarden ved klorideksponering. Til højfaste marinebeslag er 17-4PH i tilstand H900 almindelig; bekræft med dine miljødata.
Leverer I materialecertifikater?
Ja, fabriksattester (EN 10204 3.1 hvor det kræves) kan følge forsendelsen på anmodning.
Kan I bearbejde fittings til fødevarekontakt?
Ja. Specificér sanitære krav på tegningen — vi bearbejder glatte indvendige radii og de overflader, der er typiske for sanitærfittings.
What is the minimum order quantity (MOQ)?
Prototypes from 1 pc. Low-volume production typical 50-500 pcs. No forced MOQ on custom parts; unit price drops with volume.
What is the typical lead time?
Industry benchmark: instant-quote platforms deliver prototypes in 1-3 business days. Our own production: prototypes 5-10 working days, including in-house QC and shipping. Production: 2-4 weeks depending on quantity/finishing. Express options exist; finishing adds days.
How do I get a quote and what information do you need?
3D files (STEP/IGS) + 2D drawing with tolerances. Material, quantity, finish, destination country. Quote turnaround: 24-48h typical.
What tolerance should I specify?
Specify tight tolerances only on critical features. Standard ±0.1 mm covers most features. Tighter tolerance = cost multiplier; apply selectively via drawing GD&T.
How is quality controlled?
First-article inspection in our own shop before the first production order. In-process checks. Final inspection report (dimensions) with shipment. Material certs (mill test reports) on request.
Is my design protected?
NDA before file exchange. Files used only for your production. No resale of custom designs.
Which surface finish do I need?
Anodizing for aluminum corrosion/wear/color. Passivation for stainless. Plating for conductivity/steel protection. Cosmetic vs functional distinction.
How do you ship and what terms?
DHL/FedEx/UPS express for samples and small batches. Air/sea freight for production volumes. Incoterms: EXW/FOB/DAP/DDP options.
