Sheet Metal Forming Services

Q: What is your Minimum Order Quantity (MOQ)?

We operate dedicated routing for both High-Mix/Low-Volume (HMLV) and full production runs. We do not have a strict minimum order quantity. We routinely process single-piece prototypes to validate DFM and tooling clearance, seamlessly scaling to 10,000+ piece production runs once the First Article is approved.

Q: What are your standard lead times for custom sheet metal fabrication?

Standard RFQs are quoted within 24 to 48 hours. Upon PO approval and material verification, typical lead times are:Prototypes & Short Runs: 1 to 2 weeks.Full Production Runs: 3 to 4 weeks.(Note: Expedited routing is available. Lead times may adjust based on specific secondary finishes like Type III Anodizing or specialty hardware availability).

Q: Can you quote and build from a 2D PDF, or do you require a native 3D CAD model?

While native 3D models (.STEP, .IGES, .SLDPRT) are strongly preferred to ensure absolute accuracy in calculating K-factors and automated flat-pattern generation, our in-house engineering team can develop a flat pattern from a fully and correctly dimensioned 2D PDF. We will flag any missing bend radii or tolerance conflicts before quoting.

Q: Do you provide Material Test Reports (MTRs) and First Article Inspection (FAI) reports?

Absolutely. Full traceability is built into our ISO 9001:2015 QMS. We can provide Mill Test Reports (MTRs) for raw material chemical/physical properties with your shipment. AS9102 compliant First Article Inspection (FAI) reports and PPAP documentation are available upon request during the quoting phase.

Q: What happens if a formed part doesn’t meet the drawing's tolerances?

If we quote it, we own the result. We run rigid DFM checks precisely to prevent this. However, if a component ships out of spec due to tool deflection or our manufacturing error, we will re-cut, re-bend, and expedite the replacement parts at zero cost to you. Quality is guaranteed.

Sheet Metal Forming Services Capacities and Tolerances

High precision sheet metal forming at extreme thicknesses requires more than brute tonnage. It demands tight CNC control and applied material science throughout the entire metal forming process. Review ShincoFab‘s physical envelope, forming operations, and metallurgical limits below to verify we can execute your native CAD model without compromise.

Physical Envelope & Material Capacities

Ensure your design fits our shop’s operational envelope before submitting RFQs.

Maximum Bending Length: Up to 34 feet (single pass).
Carbon Steel (e.g., A36, 1018): Forming up to 1.5” thickness.
Aluminum Alloys (e.g., 5052, 6061): Forming up to 6” thickness (subject to temper and tooling).
Stainless Steel (e.g., 304, 316L): Forming up to 1” thickness.

Core Metal Forming Techniques

Automated sheet metal forming with CNC: Multi-axis backgauging for complex geometries and sequential bends.
Plate & Sheet Rolling: Capable of cylindrical, conical, and custom radii forms.
Deep drawing and stamping: Controlled material flow for high-depth-to-diameter ratio parts.
Tube Bending: Precision mandrel and rotary draw bending.
Hemming & Edge Forming: Flat, teardrop, and open hems for structural rigidity and safe handling.

Precision Engineering & Metallurgy Integration

Hitting tight tolerances (+/- 0.005”) requires more than sheer tonnage; it requires applied material science. Our CNC programmers and press brake operators mathematically account for material-specific variables before the first blank is bent:

Spring-back Compensation: Over-bending calculations specific to alloy yield strength, backed by adaptive bending sensors.
Grain Direction Strategy: Orienting bend lines perpendicularly to the grain structure to prevent micro-cracking and loss of structural integrity.
Material Hardness & Bend Radius (MBR): Tooling selection matching the K-factor and inside radius limits of your specified material gauge.

Precision Forming Equipment Specifications

Shop Floor Footprint: Configured to load, maneuver, and process heavy structural steel assemblies without material surface damage or logistical bottlenecks.

Materials Processed & Formability Limits

Avoid micro-fractures, excessive spring-back, and surface galling. We source and form the following alloys to exact industrial specifications, factoring in yield strength and elongation limits before pressing:

Carbon & Alloy Steel

Grades: A36, 1018, 1045, High-Yield Structural (e.g., A514).
Thickness Capacity: Up to 1.5”.
Forming Notes: Heavy tonnage metal forming for structural components, applied with calculated K-factors to ensure accurate inside radii and flat-pattern execution on thick, high-tensile plates.

Aluminum Alloys

Grades: 5052-H32, 6061-T6, 3003.
Thickness Capacity: Up to 6” (Subject to temper).
Forming Notes: We match the alloy to the geometry. 5052 offers excellent elongation for tight bends. For rigid 6061-T6, we strictly calculate the Minimum Bend Radius (MBR) and form across the grain to prevent cracking, fracturing, or loss of structural integrity.

Stainless Steel

Grades: 304/304L, 316/316L, 430.
Thickness Capacity: Up to 1”.
Forming Notes: Processed with dedicated, non-contaminating tooling to prevent carbon cross-contamination. This preserves the chromium oxide layer for maximum corrosion resistance in marine, medical, and food-grade environments.

Copper & Brass

Grades: C110 Copper, C260 Brass.
Forming Notes: High ductility for electrical busbars and architectural components. We utilize urethane/polyurethane die films during forming to prevent surface marring or tooling marks on high-value, aesthetic, or contact-critical parts.

Pre-Production DFM Engineering Review

We don’t just blindly feed your STEP files to the shop floor. A perfect 3D CAD model doesn’t always account for real-world material physics. That’s why our in-house engineers conduct a mandatory DFM review on every drawing prior to production, catching costly design flaws before the first laser cut is made.

Blank Development & Bend Deductions

We calculate exact K-factors based on your specific alloy grain and our precise tooling sets. This ensures the 2D flat pattern unwinds correctly so the 3D formed part hits your strict metal forming tolerances on the first try.

Tool Clearance & Bend Sequencing

We simulate complex bends in our CAM software to verify press brake tool clearance. By identifying potential flange collisions before setting up the machine, we avoid redesign delays and shop-floor rework.

Material Yield Optimization: We analyze your geometry to optimize plate nesting strategies and suggest minor radius standardization where applicable. This maximizes raw sheet utilization, minimizes scrap, and directly drives down your final cost-per-part.

Single-Source Fabrication and Finishing

Eliminate the logistical nightmare and supply chain risk of managing multiple vendors. When you utilize our turn-key fabrication services, you eliminate transit times, reduce overhead, and put an end to vendor finger-pointing. We control the quality from raw sheet to final finished assembly.
