Answers to common questions about online manufacturing quotes, CNC machining, 3D printing, sheet metal, injection molding, lead times, payment, order status, and after-sales support.

Do I need a new quote after changing the drawing or parameters?

After geometry, material, quantity, tolerance, or finishing changes, re-upload or update the configuration and requote. Minor remark-only changes can be clarified with engineers to confirm price and lead-time impact.

What tolerances can CNC machining achieve?

Typical precision parts are around ±0.05 mm; critical fits may reach about ±0.01 mm when process-capable. Achievable tolerance depends on material, rigidity, tool access, and inspection needs—call out critical dimensions on drawings.

When is 3D printing a good fit?

Best for complex internal features, lightweight structures, rapid prototypes, and low-volume functional parts. Metal and engineering plastics can combine with finishing or secondary machining. High-fit precision or high-volume unit economics often favor CNC or molding.

What files are needed for sheet metal parts?

Provide flat or formed 3D models plus thickness, material, bend, weld, hole tolerance, and finishing notes. For assemblies, include an overview so we can check interference and process sequence.

How do injection molding and tooling projects start?

Start by confirming resin, annual volume, cosmetic and assembly requirements, then evaluate tooling and sampling plans. CNC or 3D-printed validation before tooling reduces mold-change risk.

What payment methods are supported?

Online payment and corporate bank transfer are supported where available at checkout. Corporate customers can submit invoicing details after placing an order; production starts after payment confirmation.

How do I track order progress?

After login, open My Orders to see quoting, production, inspection, and shipping milestones. Key status changes are notified in-app; you can also contact an engineer for updates.

Can you issue invoices?

Yes. Submit invoice title and tax ID per checkout or order prompts. Invoice type and timing follow finance confirmation; contact us or note requirements in order messages.

What lead times apply to prototypes and low-volume runs?

Simple aluminum CNC prototypes often ship in 3–7 business days; sheet metal and 3D printing vary by process and finishing. Larger batches and complex finishing extend lead time. Note expedite requests in quote or order remarks.

Can orders be expedited?

Most standard processes can be assessed for expedite based on capacity, material stock, and finishing queues. State your target date in quote remarks; engineers will confirm feasibility and cost impact.

Do you provide inspection reports or material certificates?

Dimensional and visual inspection records can be provided as ordered. Material certs, heat treat, or special tests must be stated before order so process and cost include them. Mark critical fits and sampling rules on drawings.

How are my drawings kept confidential?

Engineering files are stored per order with access control and are not published publicly. For NDA projects, note your requirements on the contact page or in order remarks for commercial and engineering follow-up.

What if there is an issue after delivery?

Report issues soon after receipt via contact page, WeChat, or email with order ID, photos, and inspection records. Quality and engineering teams will verify and arrange rework, replacement, or agreed resolution.

Can I get a quote without logging in?

Browsing capabilities needs no login. Instant and AI quoting typically require sign-in before submit so parts, orders, and messages stay synced. Register, then upload drawings to start.

How do you protect accounts and files?

Account access and order files are permission-scoped. Keep credentials private and avoid shared logins. See the privacy policy for data handling and the confidentiality page for drawing commitments.

How do I apply for an invoice after placing an order?

After logging in, click the avatar in the top navigation bar → Personal Center → My Invoices on the left → Unissued. Find the paid order for which an invoice has not yet been issued, then click Apply for Invoice. Select a personal or company invoice title and the invoice type, then submit. To manage invoice title information, click Invoice Title Management in the upper-right corner.

How to quickly get a machining quote?

After logging in, click “AI Quoting” in the top navigation bar → enter the quotation page, upload your drawing in the chat, and confirm the quote as prompted. You can also click “Get a Quote Now” in the top navigation bar → upload your drawing → select the process, material, and quantity; after the quote is completed, you can confirm “Add to Cart,” “Proceed to Checkout,” or “Submit a Manual Quote Request” in the chat.

How can I start a conversation with a live sales representative?

After logging in, click the floating “Consultation” button in the lower-right corner to start a conversation with a live sales representative. You can also click “Messages” in the top navigation bar to view and continue the conversation, or visit the “Contact Us” page to get in touch with an engineering consultant.

Quoting

Which file formats are supported?

We accept STEP, STP, STL, OBJ, SLDPRT, 3MF and other 3D formats, plus DWG, DXF, and PDF drawings. Multiple files per upload are supported. Providing both 3D models and 2D drawings improves hole, thread, and tolerance recognition.

When does a quote require manual review?

Engineer review is triggered for deep cavities, thin walls, complex surfaces, non-standard materials, very tight tolerances, or incomplete drawings. Final pricing is confirmed via platform messages or direct engineer contact.
