What materials can you machine?
We routinely machine parts in aluminum alloys (6061, 7075, 5052), stainless steel (304, 316, 201), carbon and alloy steels, brass, copper and titanium, as well as engineering plastics such as ABS, polycarbonate (PC), POM (Delrin), nylon (PA6), PMMA and PEEK. Material selection guidance is part of our quoting service — tell us the application and we will recommend suitable grades.
What tolerances can you hold?
Standard CNC milling and turning tolerances are typically ±0.1 mm to ±0.2 mm, with precision machining to ±0.05 mm or tighter depending on the part geometry, material and process. Critical dimensions down to ±0.01 mm are achievable on suitable features. Tolerance requirements directly affect cost, so we review each drawing and confirm achievable tolerances before quoting.
Is there a minimum order quantity?
No. You can order a single prototype part. Many customers start with one to five pieces for testing and move into low-volume or mass production once the design is validated. Pricing per part improves with quantity, and we will show you the break points so you can decide.
How fast can you deliver machined parts?
Our standard production lead time is 15–25 days from approved drawings, depending on part complexity, finishing and quantity. Simple prototypes can often ship faster — tell us your deadline and we will confirm at quoting. Shipping time depends on destination and service level — express delivery usually adds 3–7 days.
How do I get a quote, and which file formats do you accept?
Send 3D models in STEP, STP or IGS format together with 2D drawings (PDF, DWG, DXF) if tolerances or critical dimensions need to be specified. Include quantity, material, finish and target delivery date. We reply with a quotation — including DFM comments where we see risk or cost-saving opportunities — typically within 1–2 business days.
Do you provide DFM (design for manufacturing) feedback?
Yes. Before production we review every drawing for machinability: wall thickness, hole depth-to-diameter ratios, internal corners, thread access, tolerance stacking and finish feasibility. Where a small design change would reduce cost or risk without affecting function, we will point it out and let you decide.
How do you ensure quality?
Quality is managed under our ISO 9001 and IATF 16949 certified system. Every project starts with an engineering and manufacturability review; production runs include first-article inspection and in-process checks at agreed checkpoints; and final inspection verifies critical dimensions before shipment using CMM measurement. Dimensional inspection reports, and material certificates where required, are available on request.
Can you provide material certificates and inspection reports?
Yes. Material certificates (mill test reports) and dimensional inspection reports can be provided with your shipment on request. If your project requires specific documentation, tell us at the quotation stage so the requirement is built into production planning rather than discovered at delivery.
Will my design files be kept confidential?
Yes. Your files are used only for quoting and manufacturing your order. We are happy to sign a mutual NDA before you send sensitive drawings, and partner factories involved in your project are bound by the same confidentiality obligations.
Do you ship internationally?
Yes. We ship worldwide with tracked express and freight options, and handle export documentation from China. Parts are packed for machining tolerances — protected against corrosion and mechanical damage — and you receive tracking as soon as the shipment leaves the factory.
What surface finishes are available?
Common finishes include anodizing (clear, black and colored), hardcoat anodizing, electroplating (nickel, zinc, chrome), powder coating, passivation for stainless steel, polishing, bead blasting and brushing. Silkscreen printing and laser marking are available for logos and part markings. We will advise which finish suits your material and application.
Should I choose CNC machining or another process for my parts?
CNC machining is usually the right choice for metal parts, tight tolerances, and prototypes through mid-volume production. For very high volumes of small plastic parts, injection molding becomes more economical despite tooling cost. 3D printing suits fast visual prototypes but with limited materials and accuracy. Send us your part and volume — we will recommend the most economical process honestly, even if it is not machining.
What industries do you serve?
Our customers come from automotive, robotics, medical devices, aerospace, electronics and consumer products, and industrial equipment manufacturing. Requirements differ — medical and aerospace demand tighter process control and documentation, automotive demands consistency across production runs — and our production planning matches those requirements.
Can you handle complex parts that need 5-axis machining?
Yes. Our workshop includes 4-axis and 5-axis machining centers for complex geometries, multi-face machining in a single setup, and parts with features that are impractical on 3-axis machines. Complex parts benefit most from early DFM review, so share your model before finalizing the design.
What are your payment terms?
Standard terms are bank transfer (T/T) with a deposit before production and the balance before shipment. For established customers, more flexible terms can be discussed. All costs — machining, finishing, inspection documentation and shipping — are confirmed in the quotation before you commit.
