FAQ's

Q:What types of custom metal parts can Shengtao manufacture from my drawings?

A:Shengtao manufactures virtually any metal component that can be machined, stamped, welded, or fabricated — provided you supply an engineering drawing or 3D model. Our 10 core capabilities cover: CNC turning & milling (up to 5-axis), progressive die stamping, deep drawing, sheet metal fabrication, structural welding & pressure vessel fabrication, hydraulic cylinder components (honed barrels, chrome-plated rods, valve bodies), automotive drivetrain & suspension parts, surface treatment (mirror polishing, electropolishing, hard chrome, zinc/nickel plating), precision tube end machining & pipe spool assembly, laser & waterjet cutting, machined pipe fittings & flanges, and exotic alloy machining (Inconel, Hastelloy, titanium, tool steel).

If your part doesn't fit neatly into one category — for example, a CNC-machined bracket that also needs zinc plating — we handle the complete process chain in-house or through qualified partners, delivering a finished part rather than a semi-finished blank. Send your drawing for a DFM review and quotation within 24–48 hours.

Q:What makes Shengtao different from other custom metal part manufacturers in China?

A:Three things set us apart:

1. True one-stop capability. Most shops either machine, or stamp, or weld. Shengtao does all three plus surface treatment under one quality system. You get a finished part with one purchase order, one shipment, and one quality package — not a multi-vendor chain where traceability breaks.

2. Process discipline, not just a QC gate at the end. We run SPC (Statistical Process Control) on critical dimensions in production, not just final inspection. Automotive customers receive PPAP documentation with Cpk ≥ 1.67. Every heat treatment batch comes with a time–temperature chart and hardness report. Every welded assembly ships with a weld map and NDE records.

3. Engineering partnership, not order-taking. Our engineers perform a free DFM review on every new part before quoting — flagging tolerance over-specifications, suggesting material alternatives that save cost without affecting function, and proposing process changes that reduce per-part price. Customers routinely save 15–30% through our DFM suggestions while maintaining full functionality.

Q:What quality standards and certifications do you follow for custom manufactured parts?

A:Shengtao is ISO 9001:2015 certified, and our automotive production processes are aligned with IATF 16949:2016 requirements (FMEA, control plans, MSA, capability studies).

For industry-specific work, we manufacture to:

• ASME Section VIII Div.1 / Div.2 — pressure vessels

• AWS D1.1 / D1.6 — structural and stainless steel welding

• ASME B31.1 / B31.3 / B31.4 — process, power, and liquid piping (pipe spools)

• EN 13445 / PED 2014/68/EU — European pressure equipment

• NACE MR0175 / ISO 15156 — sour service materials

• 3-A Sanitary Standards / FDA CFR 21 — food-grade polished components

Documentation provided with every order: material certificates (EN 10204 3.1 for all materials), dimensional inspection report, Certificate of Conformance, and batch traceability records. Optional: CMM point-cloud reports, surface roughness reports, hardness test reports, NDE reports (PT/MT/UT/RT), hydrostatic test certificates, and full PPAP packages.

Q:How do I get started — what do you need for a quotation, and how does the ordering process work?

A:Getting a quotation is free, fast, and comes with no obligation:

Step 1 — Send your RFQ to stsalesman3@stmetal001.com or WhatsApp +86 15861607265 with:

• Your drawing: 2D (PDF / DWG) or 3D model (STEP / IGES / SolidWorks)

• Material specification: grade and standard (e.g., ASTM A182 F316L, SAE 4140, 6061-T6)

• Quantity: prototype, small batch, or series production

• Surface treatment requirement: if any (polishing, plating, coating, passivation)

• Any special requirements: heat treatment, NDE, certification, target budget

Step 2 — We sign an NDA, review your files, and respond within 24–48 hours with a formal quotation including unit price, lead time, technical notes, and DFM observations.

Step 3 — After you approve the quotation, we issue a proforma invoice (PI). Production starts upon deposit receipt (typically 30–50% T/T). We share in-process photos and inspection data at key milestones.

Step 4 — Final inspection report shared → balance payment → parts shipped via DHL/FedEx (fast) or sea freight (economical) with full documentation package.

After delivery, our team remains available for any technical questions or follow-up orders. Most first-time customers receive their quotation within one business day.

Q:What is the typical lead time and MOQ for a custom metal part order?

A:We are flexible on quantity — from single prototypes to 50,000-piece/month series production:

MOQ by process type:

• CNC machined parts (from billet): no minimum — 1 pc welcome

• Laser / waterjet cut blanks: no minimum — 1 pc welcome

• Welded / fabricated assemblies: 1–5 pcs typical, depending on complexity

• Stamped parts (existing tooling): 500–2,000 pcs

• Stamped parts (new progressive die): 5,000–20,000 pcs plus one-time tooling investment

Lead times (from drawing confirmation and deposit):

• Simple CNC / laser-cut parts: 7–15 business days

• Complex multi-operation parts: 15–25 business days

• Parts with heat treatment + grinding: 20–30 business days

• Welded assemblies / pressure vessels: 25–45 business days

• New stamping tooling + first samples: 25–40 business days

Rush production (5–10 business days) is available for simple parts with a surcharge. Expedited DHL/FedEx shipping (3–7 days transit) further compresses total delivery time. Your committed delivery date is confirmed in the formal quotation.
