1. Initial Inquiry & Quotation
What information do I need for a quotation?
2D/3D drawings, materials, tolerance, quantity, and finishing requirements.
How long does it take to get a quote?
Standard quotes are usually sent within 24–48 hours.
Can you quote based on a sample part?
Yes. We can reverse engineer from a sample and provide a drawing with quotation.
2. Design & Materials Selection
Do you provide DFM (Design for Manufacturability) support?
Yes, we suggest modifications that improve castability, machining efficiency, and cost.
Can you recommend materials?
Yes, based on your industry, performance, and budget needs.
What materials can you provide for production?
We supply and machine a full range of metals including stainless steel, carbon steel, tool steel, aluminum, titanium, copper alloys, nickel alloys, and cast iron. All come with certified documentation.
How do I know which material is best for my project?
We recommend materials based on your end-use: strength, corrosion resistance, weight, heat resistance, and cost. Our team compares options to ensure both performance and price efficiency.
Can I rely on consistent material quality?
Yes. All incoming materials are inspected, batch-tracked, and accompanied by EN10204 3.1/3.2 certificates. This guarantees repeatable quality for long-term supply.
3. Prototyping & Sampling
Can I order just one prototype before bulk production?
Yes, prototypes are available to validate design and process.
Do prototypes come with inspection reports?
Yes, we provide full dimensional and material reports for samples.
Can you scale from prototype to mass production?
Yes. We start with CNC prototypes for fast validation, then move to casting and machining for large-volume supply, ensuring smooth scaling without redesign.
4.Manufacturing and Quality
What casting methods do you use?
Investment casting, sand casting, die casting, and lost foam casting.
Which casting methods are most suitable for volume production?
We provide investment casting for high-precision parts, sand casting for larger structures, and die casting for high-volume runs. Choice depends on geometry, tolerance, and budget.
What CNC machining services do you offer?
We provide precision CNC machining services including CNC milling, turning, drilling, grinding, EDM, and 5-axis machining.
Can you handle complex, high-tolerance parts?
Yes. We achieve CNC tolerances of ±0.01 mm and investment casting tolerances up to ISO 8062 CT5–CT6. This ensures parts meet aerospace, energy, and medical industry standards.
How do you control quality?
CMM, X-ray, ultrasonic testing, hardness, tensile testing, and full inspection reports.
What surface finishes can be provided for manufactured parts?
We offer surface treatment services including machining, sandblasting, anodizing, passivation, powder coating, polishing, and electroplating. We match surface treatments to functional and aesthetic requirements.
Do you provide heat treatments to extend service life?
Yes. We offer quenching, tempering, carburizing, nitriding, and other treatments to improve hardness and wear resistance.
How do you control finishing quality across batches?
By using standardized finishing parameters, test samples, and surface roughness inspection (Ra values). This ensures every batch matches the first approved sample.
5. Lead Time & Delivery
What are the typical lead times?
Prototypes: 1–3 weeks. Production: 4–8 weeks depending on volume.
Do you support urgent projects?
Yes, we offer expedited production and express shipping.
How do you package parts?
Rust-preventive oil, bubble wrap, foam padding, cardboard boxes/wooden crates, or custom packaging (available upon request).
6. Shipping & Logistics
Which shipping methods are available?
Air freight, sea freight, express courier (DHL, FedEx, UPS, TNT).
Can you handle door-to-door delivery?
Yes, we support DDP and DAP shipping terms if required.
Who arranges customs clearance?
We can handle it, or you may use your own freight forwarder.
Can you ship to multiple destinations?
Yes, we support split shipments and global delivery.
7. Payment & Invoices
What payment methods do you accept?
Bank transfer (T/T), PayPal for small orders, and L/C for large contracts.
Do you provide commercial invoices and packing lists?
Yes, all shipments include official invoices, packing lists, and HS codes.
Can I get VAT invoices or tax-compliant documents?
Yes, we issue tax-compliant invoices according to your requirements.
8. After-Sales & Long-Term Support
What if parts don’t meet the specifications?
We will rework, replace, or refund according to our warranty policy.
Do you keep tooling for future orders?
Yes, molds and fixtures are stored for repeat production.
Can you sign long-term supply agreements?
Yes, we support annual contracts to ensure stable pricing and reliable delivery.
Do you provide traceability?
Yes, with batch numbers, material certificates, and process records.
