What is the definition of sheet metal fabrication?

Custom sheet metal fabrication refers to the manufacturing progress of forming a single metal sheet into parts with a custom shape. Under this progress, it includes many manufacturing ways such as cutting, punching, folding, finishing, assembling, and more.

Parts can be used for both low volume prototypes and production parts. Since it refers to initial setup and material costs, high volume product is much more cost-saving than prototype build.

What are the advantages of custom metal fabrication?

First, custom sheet metal fabrication parts are highly durable. With good properties of high structural strength and longevity, it is good for both prototyping and end-use.

Next, the custom parts can be built from a full range of Sheet metal materials, and offer a broad range of mechanical properties.

Also, production is cost-efficient. With the high efficiency of replicating ability, the metal fabrication machines can produce parts at a low cost per unit.

While at it, due to the high efficiency of manufacturing way, parts can be built and delivered at a rapid turnaround.

Lastly, it can be customized into different sizes with all kinds of finishes.

What are the custom sheet metal tolerances?

The tolerances tend to vary depending on a wide range of factors such as the number of the manufacturing process and part feature.

Essentially, the fewer numbers of fabrication step, the higher precision for a part. Meanwhile, the hole feature has a tighter tolerance than a bending feature.

What is the common fabrication material?

There are quite several but three types mainly.

The first variety is steel including stainless steel 301, stainless steel 304, Galvanized sheet,

cold-rolled sheet, and more. Due to the cost-efficiency and good machining property, it becomes the most ideal material for sheet metal fabrication.

Copper is the next variety including copper101, copper c110, and coper260. It is ideal to make into spring prototype and parts.

Aluminum, at last, is another common material for custom sheet metal fabrication. This type of material includes Aluminum 1060, Aluminum 5052, Aluminum6061 which has good corrosion resistance and high strength-to-weight ratio.

What are the common finishes?

There are mainly four varieties for the finishes including the standard, powder coating, bead blasting, anodizing for sheet metal fabrication parts.

What are the Applications for custom Sheet Metal Fabrication parts?

Custom sheet metal fabrication parts are widely used for both indoor and outdoor environments.

The Part is made into custom enclosures, cabinets, chassis, bracket, custom hardware, Aerospace parts, and more, covering the whole manufacturing industry.

What are custom sheet metal fabrication processes?

Custom sheet metal fabrication seems a little complicated as is can be constructed into all kinds of shapes, but the whole manufacturing progress can be simply cut into three steps processes as below.

The first being cutting progress which is also called material removal progress. In this progress, there are several different ways include laser cutting, water jet cutting, plasma cutting, and punch cutting.

Among all of them, laser cutting involves the use of a laser for achieving precise cuts in sheet metal. It is more precise and energy-efficient than some other cutting processes for big size and thinks metal sheet material, which also is the most common way in our factory, especially for a prototyping build.

Punch cutting, on the other hand, it is another common way and more ideal to be used into small size application.

After the cutting, we have the forming that is also called material deformation. There are several techniques of forming that includes rolling, spinning, bending, stamping, and welding.

Lastly, it is finishing. This refers to the prototype parts being polished with an abrasive to eliminate rough spots and edges and get a smooth feature. After this process, it normally also involves finish progress such as painting and anodizing.

How much does custom sheet metal fabrication cost?

It depends. The general cost of a custom sheet metal part is dependent on several elements including the metal part size, material, complexity, and the purchasing quantity.

In a word, the less material cost and less fabrication time based on the same MOQ, the cost is lower.

What are the types of fabrication?

There are many different types of metal fabrication processes. Among them, the most common include Cutting, folding, forming, punching, stamping, welding, polishing.

To fabrication one part, we may need one or several processes above which depends on part design. For instance, we may only need the cutting process for one flat sheet part. But we may have to use all the above processes for a big cabinet product.

What is the sheet thickness range of metal fabrication?

Unless we join two pieces into one piece, sheet metal material thickness should always be consistent. Aside from that, a variety of metals is available, and the sheet thicknesses can range from 0.02 inch to 0.25 inch.

Are there any machining tips for custom metal fabrication?

The sheet metal fabrication process can be complicated, so it is important to have a set of design strategies defined when developing a sheet metal product. To get the most cost-effective part, we list a few key manufacturing practices as below.

√ Make a correct selection for the sheet metal material

In most instances, material cost takes a big portion of a metal sheet part. Thus, it is important to choose a less expensive material under your design allowing. For example, aluminum is better than copper material.

Besides, you need to know that stock sizes are much cheaper than other types of metal sheets. Be sure you make it the first option during material selection.

√ Simplify your fabrication design

First, you need to know that all sheet metal parts start flat, so the part design needs to follow with a common gauge for all features. However, you do be able to have different thicknesses, but you have to weld them together, which leads to a higher cost.

Next, we need to take good care of the bend radius. The workpiece will have a big increase for the strain when the bend radius gets smaller, so it is important to design a simple angled bends with a bigger radius.

Lastly, the smaller for holes, the cost is higher during metal sheeting cutting progress. Besides, it may easily cause distortion issues during cutting. Thus, it is ideal to keep the hold size larger than the metal sheet material thickness.

√ Fabrication Tooling considerations

In general, a complicated feature will ask for tooling which means additional time and cost. Therefore, it is advisable to make the design simple that allows for conventional press brake tooling and the other low-cost common tooling.

√ Make management for tolerances

Typically, a metal part can accept a loose tolerance for most of the features, only a few dimensions are critical for the function. By accepting a lower tolerance, we can have a lower defective rate and higher production rate. For this reason, we should only call out tight tolerances for the key features to lower the costs.

√ Keep uniform bend orientation

We need to know that we will need to make reorientation if the bends are not designed in the same direction, this cause additional manufacturing time and brings the cost up accordingly. For this reason, the designer should try to maintain uniform bends during fabrication progress.
