Standard lead times range from 5-10 business days for CNC machining and sheet metal, and 10-15 business days for injection molding tooling and production. Rush orders (24-48hr) are available for an additional fee. Exact timelines depend on complexity, material availability, and volume.

Yes. We provide tiered pricing based on quantity breaks (e.g., 1-50, 51-500, 501-2000, 2000+). Higher volumes reduce per-unit costs due to optimized cycle times and bulk material purchasing. Request a quote with your projected annual volume for the best rate.

Modifications are only accepted before CNC programming or tooling setup begins. Once production starts, changes may require rework fees, scrap costs, or lead time extensions. For urgent changes, contact your project manager immediately via email or phone.

We accept STEP (.stp/.step), IGES (.igs), SolidWorks (.sldprt), and native Parasolid formats. PDF drawings are accepted for reference only. Please ensure all files include proper tolerances, surface finish requirements, and material callouts.

Standard CNC machining holds ±0.005" (0.127mm). Precision capabilities reach ±0.001" (0.025mm) with specialized fixtures and environmental controls. Tighter tolerances may increase cycle time and cost. Consult our engineering team for GD&T-specific requirements.

Yes. Every quote includes a free DFM report highlighting potential issues such as thin walls, sharp internal corners, inaccessible drill angles, or overly tight tolerances. We suggest cost-saving optimizations without compromising function.

MetalCore is certified to ISO 9001:2015 and AS9100 Rev D (Aerospace). We also maintain ITAR registration and IATF 16949 compliance for automotive clients. All certificates are available upon request.

Yes. CoCs are included with every production shipment at no extra cost. Material Test Reports (MTRs/CMTRs) for metals and plating finishes are available for an additional fee. Specify your documentation requirements during quoting.

If a part fails inspection upon receipt, submit a photo and measurement report within 48 hours. Our quality team will initiate an NCR (Non-Conformance Report). We typically offer replacement, repair, or credit at no cost if the issue originated from our process.

Yes. We ship to 40+ countries via DHL, FedEx, and ocean freight. All exports include proper packaging, export documentation, and Incoterms compliance. Duties and customs clearance are the buyer's responsibility unless DDP terms are agreed upon.

Parts are individually wrapped in protective film, placed in foam-lined or custom-molded crates, and sealed in moisture-resistant containers. For precision optics or aerospace components, we offer climate-controlled packaging and desiccant packs upon request.
