Bakri deli, ki jih obdelujemo, zajemajo zbiralki, hladilna telesa, indukcijske tuljave, varilne elektrode, tesnila in električne komponente z visoko prevodnostjo: C10100 brez kisika za najboljšo prevodnost in uporabo v vakuumu, C11000 ETP za splošne elektro dela, C145 tellurijev baker, kadar je najpomembnejša obdelovalnost.
Baker je mehak in lepljiv — zahteva ostro polirano karbidno orodje, kontrolirane hitrosti in disciplinirano lomljenje odrezkov namesto sile. Obdelujemo s strategijami, ki se izogibajo nalaganju materiala na rezni rob, tako da površine ostanejo čiste in dimenzije držijo.

Pogosto zastavljena vprašanja
Zakaj je baker težje obdelati kot medenino?
Čisti baker je mehak in lepljiv — odrezki se zarinejo na rezne robove in pokvarijo površinsko obdelavo. Uporabljamo ostro polirano orodje, kontrolirane hitrosti in tellurijev baker (C145), kjer zasnova dopušča lažjo obdelavo.
Kako ravnate s potemnitvijo bakra?
Gol baker hitro oksidira. Za električne sestave usklajujemo kositrno ali srebrno pokalivanje; za vakuum in OFE dele pakiramo tako, da zmanjšamo ročanje in oksidacijo.
Ali lahko obdelujete zbiralki z vrtanimi in navojnimi potezami?
Da. Zbiralki, terminali in hladilna telesa so standardno delo — pošljite risbo z zahtevami glede pokalivanja in označevanja in ponudimo po njej.
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.
