Our CNC Sheet Metal Forming Processes
At Istar Machining, we offer a complete range of forming processes to meet any project need:
Bending
We use advanced air bending and coining techniques that create smooth, wrinkle-free edges. Our CNC press brakes can create precision bends with consistent angles across multiple parts.
Stamping
Our progressive die stamping creates complex parts in high volumes. This process is perfect for automotive brackets, electronics enclosures, and other parts that need to be made in large quantities.
Roll Forming
For construction and HVAC components that need consistent cross-sections, our roll forming creates perfect profiles every time. This process works great for long parts with the same shape throughout.
Spinning
Our CNC-controlled spinning creates perfectly symmetrical parts from flat sheet metal. This process is ideal for funnels, lampshades, and other round, tapered shapes.
Stretch Forming
We create aerospace-grade complex curves with our stretch forming process. This technique is perfect for making parts with gentle curves that maintain material strength.
Materials We Work With
Material Type | Thickness Range | Common Applications | Special Features |
Stainless Steel | 0.5-12mm | Food equipment, medical devices | Corrosion-resistant, FDA-compliant |
Aluminum | 0.5-10mm | Electronics enclosures, aerospace | Lightweight, excellent conductivity |
Galvanized Steel | 0.5-8mm | HVAC ducts, outdoor equipment | Weather-resistant, durable finish |
Mild Steel | 0.5-12mm | Automotive frames, fabrication | Cost-effective, easy to weld |
Titanium Alloys | 0.5-6mm | Medical implants, aerospace | Ultra-lightweight, strong |
Brass | 0.5-8mm | Decorative items, electrical | Excellent conductivity, corrosion resistant |
Copper | 0.5-7mm | Electrical components, heat exchangers | Superior conductivity, antimicrobial |
Industries We Serve
Our CNC sheet metal forming services help many different industries create the parts they need:
- Automotive – brackets, frames, and body panels
- Aerospace – lightweight components with tight tolerances
- Electronics – enclosures, chassis, and EMI shielding
- Construction – structural components and decorative elements
- Energy – solar panel mounts and electrical enclosures
- Medical – sterile equipment trays and device housings
- Food Processing – stainless steel containers and equipment
- HVAC – ductwork, vents, and control panels
Design Tips for Optimal Results
To get the best results with your CNC sheet metal forming project, follow these helpful design tips:
- Use K-factor calculations for proper bend allowances
- Avoid sharp corners to reduce stress points and cracking
- Consider grain direction to prevent material splitting
- Keep a minimum bend radius of 0.5x material thickness
- Allow enough clearance between bends (usually 2.5x material thickness)
- Add bend relief cuts where necessary to prevent tearing
Our design for CNC machining resources can help you create parts that work perfectly with our forming processes.
The Istar Machining CNC Sheet Metal Forming Process
1. CAD Design Review
We start by checking your design files to make sure they’ll work well with our forming processes. Our experts look for potential problems and suggest fixes before production begins.
2. Material Selection
We help you pick the best material for your project based on strength, weight, cost, and environmental factors. Our team can recommend alternatives if needed.
3. CNC Programming
Our engineers create detailed CNC programs that tell our machines exactly how to form your parts. This includes bend sequences, tool selection, and pressure settings.
4. Tool Setup
We select and install the right dies and punches for your specific parts. This careful setup ensures perfect results.
5. Production
Our computer-controlled machines precisely form each part according to your specifications. We monitor every step to guarantee quality.
6. Quality Control
Each part is checked against your design specifications using advanced measuring tools. We make sure dimensions, angles, and material properties meet your requirements.
7. Finishing
If needed, we add surface treatments like powder coating, anodizing, or painting to enhance the appearance and durability of your parts.
8. Assembly and Packaging
For complex products, we can assemble components before shipping. We use careful packaging to protect your parts during transit.

Frequently Asked Question
We can successfully bend materials as thin as 0.5mm, though the minimum thickness depends on the specific material. Aluminum and mild steel can be formed thinner than harder materials like stainless steel.
Consider these cost-saving strategies:
- Order in bulk when possible
- Design parts with standard bend angles
- Use common material types and thicknesses
- Combine multiple parts into single designs where possible
- Allow for standard tooling rather than custom dies
Yes! We have special heat-treated tooling specifically designed for working with titanium. Our experience with aerospace clients has given us extensive knowledge in forming titanium alloys to tight tolerances.
We offer many finishing options including:
- Powder coating in custom colors
- Anodizing for aluminum parts
- Galvanizing for rust protection
- Brushed or polished surfaces
- Chemical treatments for specific properties
