6 Ways To Save Money on Sheet Metal Fabrication

Managing production costs is a top priority for any manufacturing business. Every component, from a simple bracket to a complex chassis, impacts your bottom line. Sheet metal fabrication—a cornerstone of industries like automotive, agriculture, and construction—presents many chances for cost optimization. Strategic decisions in design, material selection, and finishing can lead to significant savings without compromising quality or performance.

Here, we’ll cover practical methods for reducing expenses in your fabrication projects. Implementing these strategies can help you lower costs, improve efficiency, and gain a competitive edge. It all comes down to making informed choices that align with both your budget and your project’s technical requirements.

Optimize Your Design for Manufacturing

The design phase is the most influential stage for controlling costs. A well-thought-out design that factors in manufacturing processes can prevent expensive rework and delays. This principle, known as Design for Manufacturability (DFM), ensures your parts are not just functional but also efficient to produce. Small adjustments can have a major impact on the final price.

Simplify Bends and Forms

Complex bends and tight radii often require specialized tooling and extra machine setup time. Each bend adds a step to the production process, increasing labor and operational costs. Where possible, simplify the geometry of your parts. Use standard bend radii that align with your fabricator’s available tooling. This simple change eliminates the need for custom setups and significantly speeds up the forming process.

It’s also necessary to consider the orientation of bends. A design review with your fabrication partner can often identify opportunities to streamline bends for maximum efficiency.

Standardize Hole Sizes and Features

Standardization is a powerful tool for cost reduction. Using consistent hole sizes across a part or project minimizes the number of tool changes required during laser cutting or punching. Every tool change adds time to the production cycle. By designing with a limited set of standard hole diameters, you enable a more continuous and efficient manufacturing flow.

This concept extends to other features like slots, tabs, and cutouts. Adhering to common dimensions that work with standard tooling avoids the expense associated with custom punches or complex laser cutting paths.

Choose the Right Material and Thickness

Material selection is a direct and significant component of your project’s cost. The type of metal you choose and its thickness have a ripple effect on everything from raw material expense to processing time. Making an informed choice here is crucial for saving money on sheet metal fabrication.

Evaluate Material Costs and Properties

Common materials like carbon steel, stainless steel, and aluminum have different price points and properties. Carbon steel is often the most cost-effective option, but it requires a protective finish to prevent corrosion. Stainless steel offers inherent corrosion resistance but comes at a higher price. Aluminum is lightweight and corrosion-resistant, but it can be more expensive than steel.

Your decision should balance cost against the functional needs of the application. Keep in mind that a slightly more expensive material may save money in the long run by eliminating the need for secondary processes.

Select the Thinnest Gauge Possible

The thickness of the sheet metal, or its gauge, directly influences cost. Thicker materials are more expensive to purchase and take longer to cut and form. In many situations, it’s smart to use the thinnest gauge capable of providing the necessary strength and rigidity for the part’s function.

Adding features like strengthening ribs or flanges can often provide the required structural integrity while allowing you to use a thinner, less expensive material. You can use engineering analysis to determine the minimum thickness required. A collaborative review with your fabricator can also provide valuable insight into how different gauges will perform during the manufacturing process.

Consolidate Parts and Reduce Welds

Part complexity and assembly requirements are major cost drivers. Your team must cut, form, and handle every individual component. During assembly, welding adds significant labor, time, and material expenses. A clever design can often reduce the total number of individual pieces required, which ultimate lowers the amount of labor involved in handling.

By redesigning an assembly to use fewer, more intelligently formed parts, you can eliminate entire production steps. For example, instead of welding two flat pieces together to create an angle, a single piece of metal can be bent. This approach not only saves on welding but also results in a stronger, more consistent final product. Look for opportunities to incorporate features like tabs and slots that allow parts to self-locate, reducing the need for complex fixtures during assembly.

Leverage Your Fabricator’s Capabilities

Your fabrication partner is more than just a supplier; they are a resource. Their expertise and equipment can guide you toward more cost-effective solutions. Engaging with them early in the process opens the door to valuable feedback that can streamline production.

Discuss your design with their engineers. They understand the capabilities and limitations of their machinery. They can advise on optimal bend radii, efficient nesting for laser cutting, and tolerances that are practical for their equipment. A fabricator might suggest a minor design tweak that drastically reduces machine time or material waste. A collaborative approach empowers you to optimize your designs, leading to lower costs and faster turnarounds. This is where our metal fabrication services can provide immense value, turning your concepts into cost-effective realities. At Greenline Metals Inc., we understand the importance of achieving great quality with minimal lead times, and we’re ready to help your business complete projects in a cost-effective, efficient way.

Optimize Finishing and Secondary Operations

Finishes like powder coating, painting, and plating protect the part and improve its appearance, but they also add to the final cost. It is important to specify only the necessary finishes for the part’s application. A part that will sit within a larger assembly may not need the same high-quality cosmetic finish as an exterior panel.

Consider the material choice in relation to finishing. Using a corrosion-resistant material like stainless steel or aluminum might eliminate the need for painting or plating altogether. While the raw material cost is higher, the savings from skipping a secondary finishing process can result in a lower total cost. When a finish is necessary, explore cost-effective options like powder coating, which often provides a durable and attractive finish at a reasonable price point.

Plan for Efficient Production Runs

The quantity of parts you order at one time has a major effect on the per-unit price. Setting up machinery for a production run involves a fixed amount of time and labor, regardless of whether you are making 10 parts or 1000. These setup costs will spread across the total number of units produced.
