Frequently Asked Questions

A.Quotes are completely free — no service fee. You can reach us via: ‧Phone: +886-4-2335-6451 (Mon - Fri 08:00 - 17:30, Taiwan time) ‧Email: agesmyth@gmail.com When requesting a quote, please include: ‧Drawing (2D or 3D) or product photo ‧Material specifications (e.g., SUS304, A6061) ‧Estimated quantity ‧Surface finish requirements (if any) ‧Desired lead time We typically respond with a quote within 1-2 business days. For special specifications or on-site evaluation, we will follow up by phone to confirm details.

A.Sure! Two common ways: 1. Reverse-engineer from sample — send the part to our factory and we'll measure it, create drawings, then machine. 2. On-site visit — if shipping is inconvenient, we'll schedule a sales visit to evaluate. We'll quote the drafting fee upfront for your approval before any work begins. If we also handle the production, drafting fees can typically be credited toward your next order.

A.We accept all common engineering drawing formats: ‧2D: DWG (AutoCAD), DXF, PDF ‧3D: STEP (.stp), IGES (.igs), STL ‧Hand-drawn sketches: Acceptable, but quote precision may be limited 3D drawings help with CAM programming and shorten lead times. For unusual formats or files needing conversion, please mention it when requesting a quote.

A.No mandatory MOQ — we accept orders starting from 1 piece. Prototype, R&D, and custom orders are part of our daily work. A few practical notes: ‧Small orders — fixed costs (machine setup, fixturing) are spread over fewer units, so unit price is higher. ‧Volume orders — larger batches mean lower average unit cost. ‧Prototype to production — tooling costs can usually be credited toward later production runs. Final pricing is based on the individual quote.

A.For domestic first-time clients we use Net 30 as the standard term; long-term clients have flexibility based on the relationship. For international orders, we'll discuss payment terms (T/T, L/C, etc.) with you separately. Invoice format can be tailored to your needs (standard tax invoice, no-invoice format, etc.) — just let us know when ordering.

A.Domestic orders: ‧Single piece / small batch: 7-14 business days ‧Production / large batch: 14-30 business days depending on volume and complexity ‧Rush orders: Negotiable; in some cases we can deliver in 3-5 days. Please flag at order time. International orders: Lead times to be discussed (including shipping time). Holiday periods (Lunar New Year, Tomb-Sweeping holidays, etc.) will be announced separately. We recommend ordering in advance.

A.Sure. Common partial-shipment options: ‧By quantity — e.g., 1,000 pieces total, 200 pieces per batch, monthly shipments ‧By completion progress — finished items ship first, remainder follows ‧By your operational pace — aligned with your production or inventory schedule Just let us know your batch needs at order time so we can plan production and shipping together.
