Overview of Forming Processes

Sheet metal forming is a foundational process in modern fabrication. It involves reshaping flat metal stock into a desired geometry without removing material. As a seasoned sheet metal forming company, we rely on several methods based on geometry, volume, and material characteristics.

• Bending: The most common method, using press brakes to create angled parts like enclosures, brackets, and chassis.
• Stamping: Ideal for high-volume runs, where dies are used to punch and shape sheet metal in one or more hits.
• Rolling: Used to produce cylindrical or curved parts like ducts, pipes, and cones.

Each process plays a vital role in our custom metal forming services, from prototypes to full-scale production runs.

Materials Used in Sheet Forming

Material selection directly impacts formability, tooling wear, and finished part quality. We commonly work with:

• Aluminum: Lightweight and corrosion-resistant, ideal for aerospace and electronics.
• Stainless Steel: Durable and aesthetic, widely used in food, medical, and architectural sectors.
• Cold Rolled Steel: Cost-effective and versatile, often used in general industrial applications.
• Copper and Brass: Excellent for electrical components and decorative finishes.

Our experience in formable metal alloys ensures each part meets its mechanical and cosmetic goals.

Equipment Overview

Precision starts with the right tools. In our facility, we use advanced forming equipment:

• Press Brakes: CNC-controlled machines for high-precision bends with programmable back gauges and angle sensors.
• Hydraulic Presses: For deep draws and heavy stamping applications.
• Roll Formers: Best for continuous part runs, including gutters, channels, and structural profiles.
• Tooling & Dies: Custom dies matched to your design for consistent results across production runs.

We’re proud to be a precision sheet metal forming specialist equipped for everything from short-run jobs to mass production.

Forming Tolerances and Standards

Proper tolerancing is essential in forming. Too tight, and you risk cracking or high costs; too loose, and parts won’t assemble. Standard forming tolerances depend on:

• Material type and thickness
• Bend angle and radius
• Flat pattern accuracy and springback compensation

Our in-house QA team checks bend angles, dimensions, and hole positions during every shift.

Common Mistakes and How to Avoid Them

Even experienced engineers can fall into common traps. Here are a few to avoid when designing or ordering formed parts:

• Ignoring bend radius: Every material has a minimum bend radius—violating it leads to cracking.
• Over-tight tolerances: Drives up cost and may be unnecessary in real-world use.
• Poor material choice: Wrong alloy = poor formability or inconsistent finishes.
• Hole too close to bend: Leads to distortion or tool interference.

Our engineers review your drawings and offer DFM (Design for Manufacturability) feedback to ensure smooth, efficient forming.

When to Use Forming vs. Other Methods

Forming is a fantastic process—but it’s not always the right one. Here's when it shines, and when another method may be better:

Choose Forming When:

• You need high-strength parts without welding or fasteners
• The design has repeatable bends and defined geometry
• You want to reduce part count by folding single-piece designs

Consider Alternatives When:

• You need extremely intricate shapes (consider laser cutting + welding)
• Material is too brittle for forming (e.g., castings)
• You require multi-axial curves (consider stamping or machining)

As a sheet metal forming partner, we help you evaluate the right method, balancing cost, durability, and design complexity.
