Pemesinan CNC Kuningan

Brass CNC machined fittings and electrical terminals on a workshop bench

Komponen kuningan yang kami mesin mencakup fiting perpipaan, bodi katup, kopling, terminal listrik, dan komponen dekoratif: kuningan free-cutting C36000 untuk komponen bubut volume tinggi, kuningan cartridge C260 ketika pembentukan dan kemampuan kerja dingin berperan, kuningan bebas timbal C693 untuk kebutuhan air minum.

Kuningan adalah salah satu logam paling mudah dimesin — ia berjalan pada kecepatan spindel tinggi dengan kontrol serpihan yang sangat baik. Kami menandai callout timbal dan pelapisan selama tinjauan DFM sehingga komponen jadi memenuhi persyaratan air minum dan RoHS bila dispesifikasikan.

Pertanyaan yang sering diajukan

Kuningan mana untuk fiting air minum?

C693 bebas timbal (Eco Brass) adalah pilihan standar di mana regulasi air minum berlaku; konfirmasikan kebutuhan rendah timbal regional Anda pada gambar dan kami memmesin sesuai itu.

Apakah ulir kuningan mudah menyatu atau menempel?

Kuningan dimesin dengan bersih, tetapi ulir halus dapat mengunci di bawah beban. Kami mengontrol geometri pemotongan dan finishing permukaan, serta merekomendasikan anti-seize atau pelapisan bila perakitan bersifat permanen.

Bisakah Anda menangani kebutuhan ketebalan pelapisan?

Ya. Cantumkan jenis dan ketebalan pelapisan pada gambar — kami memmesin dimensi kritis dengan allowance pelapisan sehingga ulir dan pasungan terlapisi tetap dalam toleransi.

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.
