Komponen plastik yang kami pemesin mencakup prototipe, isolator, roda gigi, bushing, komponen aus, komponen PEEK grade medis, dan lensa akrilik optik: ABS dan POM (Delrin) untuk pekerjaan umum, nilon 6/6 untuk ketahanan aus, PEEK untuk suhu tinggi dan sterilisasi, PTFE untuk aplikasi kimia dan gesekan rendah.
Plastik terpemesin berbeda dari logam — ekspansi termalnya sekitar sepuluh kali lebih tinggi dan panas menumpuk dengan cepat, sehingga kami menggunakan mata pahat tajam terpolish, kecepatan konservatif, dan frais searah agar tepi tidak meleleh atau berkerabu. Toleransi mencerminkan materialnya, bukan harapan.

Toleransi
ISO 2768-m umum; ±0.05 mm tipikal, ±0.02 mm pada fitur 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
PEEK atau Delrin untuk aplikasi saya?
Delrin (POM-C) cocok untuk komponen mekanis presisi dengan biaya sedang; PEEK cocok untuk suhu tinggi, sterilisasi, dan paparan kimia dengan harga premium. Kami memberi rekomendasi berdasarkan lingkungan pengoperasian.
Mengapa toleransi plastik lebih lebar daripada logam?
Plastik mengembang dan relaks terhadap suhu dan tegangan sekitar sepuluh kali lebih besar daripada logam. ±0.05 mm adalah tipikal; kami menahan ±0.02 mm pada fitur kritis dengan material yang stabil dan proses yang terkendali.
Bisakah Anda mememesin komponen akrilik bening?
Ya. Kami mememesin akrilik dengan mata pahat tajam dan memoles hingga bening transparan bila geometrinya memungkinkan — kirimkan gambar dan tunjukkan permukaan mana yang harus tetap optik jernih.
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.
