Aluminij je najbolj obdelovana družina zlitin v naši delavnici: 6061 za splošne strukture, 7075 za visokotrdnostne nosilce, 2024 tam, kjer je pomembna utrujenost, poleg litih zlitin za strankine surovce.
Eloksiranje zajema prosojno, črno in trdo eloksiranje ter ujemanje barv, tako da obdelani aluminijasti deli prispejo zaključeni in pripravljeni na montažo.

Pogosto zastavljena vprašanja
Katero kakovost aluminija naj izberem?
6061-T6 pokriva večino nosilcev in ohišij; izberite 7075-T6, kadar je razmerje trdnost/teža kritično. Pošljite nam obremenitveni primer in svetovali vam bomo.
Ali eloksiranje spreminja dimenzije?
Da, rahlo. Tip II doda približno 0.005–0.015 mm na površino; kritične dimenzije vnaprej kompenziramo, kadar je eloksiranje določeno.
Ali lahko ujamete barvo eloksiranja po naročilu?
Da, ob odobritvi vzorca. Podajte barvno kodo ali fizični vzorec in barvo ujamemo pred proizvodno serijo.
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 material should I choose?
Function first: strength, weight, corrosion, cost. Common pairings: 6061 general, 304/316 corrosive env., PEEK medical. See materials guide pages.
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.
