Precision Sheet Metal Fabrication: Laser Cutting, CNC Bending & Stamping Capabilities
Introduction
Precision sheet metal fabrication is the foundation of modern industrial manufacturing. From appliance housings to energy storage enclosures, the accuracy, repeatability, and surface quality of fabricated metal parts directly determine the performance and reliability of the final product. At DINGPRECISION, we operate 85+ metal fabrication machines under one roof — a scale that enables true one-stop service from raw sheet to finished assembly. This article details our core fabrication capabilities, tolerance standards, and what makes our process different.
Laser Cutting: ±0.1mm Precision at Scale
Laser cutting is the first shaping operation for most sheet metal parts. Our 15 fiber laser cutting machines (6,000W each) deliver both speed and precision across a wide material range.
Material | Maximum Thickness | Typical Tolerance | Edge Quality |
Carbon Steel (SPCC/SGCC) | 25 mm | ±0.1 mm | Clean, minimal dross |
Stainless Steel (304/316) | 16 mm | ±0.1 mm | Oxide-free with N₂ assist |
Aluminum (5052/6061) | 12 mm | ±0.15 mm | Minimal burr |
Copper / Brass | 8 mm | ±0.15 mm | Requires O₂ assist |
Why 6,000W Fiber Lasers?
Compared to older CO₂ laser technology or lower-power fiber lasers, our 6,000W machines offer:
Faster cutting speeds — reducing cost per part
Better edge quality on thick materials — less secondary deburring
Nitrogen-assisted cutting for stainless steel — eliminating oxide formation that would compromise subsequent welding or coating
Smaller heat-affected zone (HAZ) — preserving material properties near the cut edge
CNC Bending: 20 Press Brakes, 8.4m Maximum Length
CNC bending transforms flat laser-cut blanks into three-dimensional structures. Our 20 CNC press brakes provide the capacity and precision to handle everything from small brackets to full-size enclosure panels.
Parameter | Capability |
Maximum bending length | 8,400 mm |
Minimum bend edge | 8 mm |
Bending angle tolerance | ±0.5° |
Repeatability | ±0.05 mm |
Tonnage range | 40T – 600T |
Springback Compensation
Every metal alloy exhibits springback — the tendency to partially return to its original shape after bending. Our CNC controllers use material-specific springback compensation tables developed from production data across thousands of part numbers:
Material | Thickness | Typical Springback Angle | Compensation Method |
SPCC (cold-rolled) | 1.0–2.0 mm | 2–4° | Over-bend + dwell |
SUS304 | 1.0–3.0 mm | 3–6° | Over-bend + CNC dwell |
AL5052 | 1.5–3.0 mm | 4–8° | Over-bend + radius adjustment |
Typical Process Route Example: Microwave Oven Housing
A typical microwave oven outer housing requires 14 sequential operations across four workstations:
Material In → Laser Cutting (flat pattern) → Deburring →
CNC Bending (4 sides) → Stamping (louvers/vents) →
Welding (corner joints) → Surface Treatment →
Assembly → Quality Inspection → Packaging
This integrated process chain — all under one roof — eliminates the logistics delays and quality risks of multi-vendor fabrication.
Metal Stamping: 50 Presses up to 500 Tons
For high-volume production, stamping offers the lowest per-unit cost and highest repeatability. Our 50 mechanical and hydraulic presses cover a broad capability spectrum:
Press Type | Tonnage Range | Quantity | Typical Application |
High-speed (mechanical) | 25–160T | 30 | Small brackets, clips, terminals |
Medium (mechanical) | 160–315T | 15 | Enclosure panels, mounting plates |
Heavy (hydraulic) | 315–500T | 5 | Structural frames, base plates |
Progressive Die vs. Transfer Die
Process | Best For | DINGPRECISION Capability |
Progressive Die | High volume, complex geometry, tight tolerances | In-house die design + manufacturing |
Transfer Die | Large parts, multiple operations | Up to 500T, 6-station transfer |
Single-hit | Prototypes, low volume | Quick-turn tooling, 3–5 day lead time |
Quality Assurance: In-Process Control
Our fabrication quality system goes beyond final inspection:
First Article Inspection (FAI): Every new production run starts with a full dimensional check of the first piece
In-Process Checks: Laser-cut blank dimensions verified every 50 pieces; bend angles checked every 30 minutes
CMM (Coordinate Measuring Machine): Full 3D dimensional verification for critical tolerances
Surface Quality: Visual inspection under 500 lux lighting for scratches, dents, and burrs
Conclusion
Precision sheet metal fabrication requires three things: the right equipment, the right process control, and the experience to know how materials behave. DINGPRECISION brings all three together in a single, integrated facility. From a single prototype to 100,000-unit production runs, our 85-machine shop floor is ready.

FAQ
Q: What is the tightest tolerance you can hold on laser-cut parts?:
A: We routinely achieve ±0.1 mm on laser-cut features for materials up to 16 mm thickness. For critical features on thinner materials (≤3 mm), ±0.05 mm is achievable with process optimization.
Q: What is the largest sheet size you can handle?:
A: Our laser cutting tables accommodate sheets up to 3,000 × 1,500 mm, and our largest CNC press brake handles bending lengths up to 8,400 mm.
Q: Do you offer prototyping and low-volume production?:
A: Yes. Our flexible manufacturing system handles quantities from 1 piece (prototype) to 100,000+ pieces (production). Quick-turn tooling for stamping prototypes is available in 3–5 days.
Q: What materials do you work with most frequently?:
A: Our most common materials are SPCC/SGCC cold-rolled steel, SUS304/316 stainless steel, and AL5052/6061 aluminum. We also process copper, brass, and specialty alloys upon request.
