Common Questions From Engineers & Buyers
These are the questions we receive most often before quotation, sample approval, and production.
Quotation & Files
Send us your 2D drawing or 3D file together with material, quantity, tolerance, and finishing requirements. We usually reply within 24 hours with a clear quotation.
We commonly accept STEP, IGES, STL, PDF, and DWG files. Clear drawings with notes on tolerance, thread details, and surface finish help us quote more accurately.
The most useful information includes material, quantity, finish, critical dimensions, tolerance requirements, and whether the project is for prototype, small batch, or production.
Engineering & Production
Yes. We can review manufacturability and suggest practical improvements to reduce machining difficulty, improve consistency, and control overall cost.
Yes. We support prototype parts, pilot runs, and small-batch production. This is especially useful for startups, product development teams, and custom equipment projects.
Absolutely. We manufacture according to customer drawings, tolerances, finishing requirements, and inspection standards provided for the project.
Lead Time & Quality
Typical lead time is around 7 to 21 days depending on part complexity, order size, machining process, and any required surface treatment.
Yes. We can produce samples first for confirmation before moving into larger quantity production. This helps customers verify fit, function, and appearance.
Standard machining tolerance can reach ±0.01 mm depending on material, geometry, and process. Tighter tolerances can be discussed based on part requirements.
Yes. We regularly support customers in Europe and North America with export experience, English communication, and reliable international delivery.
