我們加工的銅零件涵蓋匯流排、散熱器、感應線圈、焊接電極、密封件與高導電電氣零組件:導電性與真空用途最佳的 C10100 無氧銅、一般電氣用途的 C11000 ETP,以及切削性最重要時的 C145 碲銅。
銅質軟且黏——需要銳利的研磨硬質合金、受控的轉速與嚴謹的斷屑,而非蠻力。我們採用避免積屑瘤的策略,讓表面保持潔淨、尺寸得以維持。

常見問題
為什麼銅比黃銅難加工?
純銅質軟且黏——切屑會焊在刀刃上並破壞表面粗糙度。我們使用銳利的研磨刀具、受控轉速,並在設計允許時採用切削性較好的碲銅(C145)。
你們如何處理銅的變色問題?
裸銅氧化很快。電氣組裝件我們會協調鍍錫或鍍銀;真空與 OFE 零件則以包裝減少接觸與氧化。
可以加工帶鑽孔與攻牙特徵的匯流排嗎?
可以。匯流排、端子與散熱器是常規工件——請寄送附電鍍與標識要求的圖面,我們據以報價。
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.
