When designing custom sheet metal parts, there are a few tricks of the trade that can save you time, money, and headaches. Let’s dive into some key tips that will help your designs look great on paper and work seamlessly in the real world.

Choose the Right Sheet Metal for the Job

First, selecting the right type of sheet metal is crucial. Different projects call for different materials, and making the right choice early on can make or break your design.

Aluminum is lightweight and resistant to corrosion, making it perfect for outdoor applications. Stainless steel offers exceptional strength and durability, ideal for heavy-duty projects.

And let’s not forget about copper—it’s great for electrical components because of its excellent conductivity. Knowing your materials will set you up for success right from the start.

Keep Costs Low by Designing With Standard Industry Gauges

Next, let’s talk about cost. Nobody likes to overspend, and one way to keep your budget in check is by designing with standard industry gauges. Sticking to common thicknesses will make your parts easier to manufacture and more affordable.

Standard gauges are widely available and typically less expensive than custom thicknesses. Plus, using standard gauges means you can produce more parts quickly, getting your project off the ground faster.

Embrace Simplicity: Ensure Your Bends Translate From Design to Reality

Complex designs might look impressive, but simplicity often wins the day in sheet metal fabrication. When designing bends, keep them straightforward to ensure they translate accurately from your CAD model to the final product.

Overly intricate bends can lead to manufacturing errors and increased costs. Stick to simple, consistent bends to achieve reliable, high-quality results. Remember, sometimes less is more.

Incorporate Design for Manufacturing (DFM) Principles

Design for manufacturing (DFM) principles are your best friend when creating efficient and manufacturable sheet metal parts. DFM involves designing with the manufacturing process in mind, reducing the likelihood of costly and time-consuming modifications down the line.

For instance, consider the tools and machines that you’ll use during production and design parts that will suit those processes. This approach will help streamline production and enhance the quality of your parts.

Find the Right Tolerance Requirements for Your Sheet Metal Parts

Lastly, let’s talk about tolerance. Finding the right tolerance requirements is key to fitting parts together without unnecessary stress. Too tight of a tolerance can cause production difficulties and increased costs, while too loose of a tolerance might result in parts that don’t fit as intended.

Striking the right balance is essential. Work closely with your manufacturer to determine the appropriate tolerances for your application, considering the capabilities of their equipment and processes.

Designing custom sheet metal parts is a blend of art and science. Following the advice from Thin Metal Sales will help you maintain a successful enterprise throughout the design and production processes. The goal is to create functional, cost-effective, and manufacturable designs.

These principles are just as applicable if you’re working on a project involving copper sheet metal fabrication. We encourage you to contact our team to find the best thin-gauge sheet metals in the industry.
