黃銅CNC加工

Brass CNC machined fittings and electrical terminals on a workshop bench

我們加工的黃銅零件涵蓋水管接頭、閥體、接頭、電氣端子與裝飾零組件:大批量車削件用 C36000 易切削黃銅,重視成形與冷作性時用 C260 彈殼黃銅,飲用水需求則用 C693 無鉛黃銅。

黃銅是切削性最好的金屬之一——可在高主軸轉速下運行且切屑控制極佳。我們會在DFM審查時標記鉛含量與電鍍標註,讓成品在指定之處符合飲用水與 RoHS 要求。

常見問題

飲用水接頭該用哪種黃銅?

適用飲用水法規的場合,標準選擇是無鉛 C693(Eco Brass)。請在圖面上確認您所在區域的低鉛要求,我們會據以加工。

黃銅螺紋會咬死或卡住嗎?

黃銅切削乾淨,但細螺紋在受力下可能咬住。我們控制切削幾何與表面粗糙度,並在永久組裝的場合建議使用防咬劑或電鍍。

可以處理鍍層厚度要求嗎?

可以。請在圖面上標明鍍層類型與厚度——我們會為關鍵尺寸預留鍍層裕度,讓電鍍後的螺紋與配合仍維持在公差內。

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.
