常見問題
船舶環境該用哪種不鏽鋼？
氯化物環境的預設選擇是 316L。高強度船舶五金常用 H900 狀態的 17-4PH；請以您的環境數據確認。
你們提供材料證明嗎？
提供，原廠材質證明（必要時可為 EN 10204 3.1）可依需求隨貨提供。
可以加工食品級接頭嗎？
可以。請在圖面上標明衛生等級要求——我們會加工平滑的內圓角，以及衛生接頭慣用的表面粗糙度。
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 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.
