|---|---|---|---|
| Aluminium 6061 | T6 (larutan dan pengerasan usia) | Mudah: bebas-potong, kontrol serpihan baik | Braket, housing, fixture, prototipe hingga produksi |
| Aluminium 7075 | T6 / T651 | Lebih sulit: aus perkakas lebih besar, butuh setup kaku | Komponen berkekuatan tinggi, kritis bobot; tidak untuk pengelasan |
| Baja tahan karat 304 / 304L | Annealed | Pengerasan-kerja: kecepatan lebih rendah, feed positif | Ketahanan korosi umum, peralatan makanan dan proses |
| Baja tahan karat 316 / 316L | Annealed | Lebih liat dari 304: aus perkakas lebih besar | Paparan klorida, laut, medis, dan farmasi |
| Baja karbon 1018 / 1045 | Sebagaimana digulung / dinormalkan | Mudah hingga menengah; butuh perlindungan anti karat | Poros, pelat, lasan, bodi perkakas |

| Pasivasi | Mengangkat besi bebas dan memulihkan film oksida | Komponen baja tahan karat setelah pemesinan |
| Pelepasan tegangan / perlakuan panas | Melepas tegangan sisa sebelum atau sesudah pemotongan | Dinding tipis dan toleransi ketat yang harus bertahan pemesinan |
Toleransi
ISO 2768-m; ±0.01 mm pada fitur pemesinan kritis.
| Callout | Yang dibutuhkan | Efek pada biaya dan waktu pengerjaan |
|---|---|---|
| Umum: ±0.25 mm / ±0.010 in | Perkakas standar, pemeriksaan dimensi | Dasar: tanpa tambahan biaya |
| Standar: ±0.13 mm / ±0.005 in | Mesin dalam kondisi baik, pemeriksaan artikel pertama | Tambahan kecil; default penawaran yang lazim |
| Ketat: ±0.025 mm / ±0.001 in | Perkakas digerinda atau diamond, kontrol suhu, CMM | Lompatan tahap: potongan lebih lambat plus inspeksi penuh |
| Presisi: ±0.013 mm / ±0.0005 in | Paseran akhir, gauge, lingkungan terkendali | Pemesinan menentukan harga; sering operasi terpisah |
| Posisi / sudut (GD&T) | Kontrol datum, satu setup untuk fitur yang saling terkait | Bergantung pada berapa banyak setup yang dicakup datum |
| Finishing permukaan Ra 0.8 µm atau lebih halus | Stepover lebih halus, pemolesan atau paseran finishing | Menambah satu langkah proses, bukan sekadar waktu pemesinan |

Pertanyaan yang sering diajukan
Grade aluminium mana yang sebaiknya saya pilih?
6061-T6 mencakup sebagian besar braket dan housing; pilih 7075-T6 ketika rasio kekuatan-berat bersifat kritis. Kirimkan kasus bebannya dan kami akan menyarankan.
Apakah anodisasi mengubah dimensi?
Ya, sedikit. Tipe II menambah sekitar 0.005–0.015 mm per permukaan; kami mengompensasi dimensi kritis secara antisipatif ketika anodisasi dispesifikasikan.
Bisakah Anda menyesuaikan warna anodisasi kustom?
Ya, tergantung persetujuan sampel. Sediakan kode warna atau sampel fisik dan kami menyesuaikannya sebelum batch produksi.
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.
