Main Process for Sheet Metal
The sheet metal manufacturing process begins with designing the part using computer-aided design (CAD) software to generate precise drawings and models. Afterward, the appropriate materials are chosen based on the design requirements and are cut into basic shapes, typically through methods like laser cutting or waterjet cutting. Next, the part is formed into its final shape through processes such as stamping, bending, and other techniques. If needed, welding or other joining methods are used to assemble the part. To enhance both the appearance and durability, surface treatments such as buffing, painting, or plating are applied. After performing quality inspections to ensure each part meets the required standards, the part is packaged and prepared for shipment, completing the production process.
cutting
- Before manufacturing the parts, it's essential to create designs using computer-aided design (CAD) software and plan the machining steps according to the intended processes.
- Next, select the appropriate sheet metal and cut it to the required size for the planned operations.
- Based on the machining program, set parameters like the punching and shearing force, speed, and tool positioning.
- Once the program is ready, load it into the machine control system.
The machine automatically positions the sheet metal, then punches and shapes it in the punching section, followed by cutting and forming it in the shearing section.
stamping
- Stamping molds are designed based on the product requirements. This is often done using CAD software for 3D design to ensure the molds can make the parts you need.
- Once you have the design drawings, you make the stamping dies using equipment like machining centers (CNC machines), electric discharge machines (EDM), and grinding machines.
- You choose the right sheet metal based on the requirements of the stamped part. Common materials include stainless steel, carbon steel, aluminum alloy, copper alloy, and so on.
- You get the material ready by doing things like cutting it to the right size.
Set up the mold: Put the mold you made into the punch press.
Fine tune the machine: Adjust the settings on the press (press force, stroke, speed, etc.) to make sure the die and the machine work well together.
Start making parts: Begin a production run where a sheet of metal is cut, formed or stretched by the die to make the part you want.
Make lots of parts: For high-volume production, you’ll often use progressive dies and automatic feeding equipment to make parts faster.
bending
- Use CAD software to make design drawings of the parts.
- Decide how to bend the part and what settings to use on the machine to do it.
- Choose the right kind of sheet metal for the part, considering things like how thick it is, what it’s made of (like stainless steel or aluminum), and how strong it is.
- Pick the right top and bottom dies for the job. Set the settings on the machine, like how hard it clamps down, how far it bends, and how much space is between the dies.
Position the material: Position the sheet metal between the dies of the bending machine so it’s in the right place.
Bend it: Use the bending machine to push the sheet metal until it bends along the line you want it to bend along.
Bend it again: Repeat the bending process in the order and direction you planned for parts that need to be bent more than once.
welding
- Design your welds to be strong enough for the loads and conditions they’ll experience.
- Choose the right welding process for the material, thickness, joint type, and production conditions. You might use arc welding, gas-shielded welding, laser welding, and so on.
- Select the right materials for your design.
- Make sure the metal is clean. Remove oil, rust, paint, and anything else that’s on the metal where you’ll be welding.
Preheating: Preheat as necessary to reduce welding stress and distortion.
Positioning and clamping: Position and clamp the parts you’re welding accurately to hold them in place while you’re welding.
Welding: Weld according to the welding procedure to make sure the welds are good enough for your design.
Welding control: Watch the welding parameters (like current, voltage, and speed) and watch the shape of the weld as you’re welding. Adjust if you need to.
riveting
- Choose the right rivet (size and material) for the type and thickness of the things you want to join.
- Decide where and how many rivets you need and how strong the joint must be.
- Get the things you want to join ready, making sure they’re clean and don’t have any grease on them.
- Mark where the rivets go based on your design.
Assemble the mold: According to the type and size of the selected rivet, install the appropriate mold to the riveting machine.
Adjust Pressure: Set the pressure of the riveting machine to ensure that the rivets can penetrate the material smoothly and form a tight connection.
Place Workpiece: Place the pre-prepared part under the riveting machine to ensure that the rivets are correctly positioned.
Execute Press Rivet: Activate the riveting machine and the rivets are pressurized to penetrate the material and form an extension or curl on the backside to securely connect the parts.
finishing
- Clean the surface to get rid of grease, dust, rust, or anything else that might be on there. You can use a solvent, a strong cleaner, or an ultrasonic cleaner.
- Smooth out any sharp edges that were created when the metal was cut. You don’t want those edges to damage the equipment or the final product.
- Make the surface rougher so the coating will stick better. You can do this by sanding it, blasting it with sand or beads, or using a strong cleaner to eat away a little bit of the surface.
- For painting or certain chemical treatments, you’ll need to let the coating dry by baking it or just letting it sit out. For some anodized treatments, you’ll need to put a seal on them to make them work better.
Electroplating: We put the parts we’re treating in a bath of electrolyte that has metal ions in it. The metal ions stick to the part because of the electric current flowing through the bath. This forms a layer of metal on the part.
Anodic oxidation: We put the metal parts in a bath of electrolyte that has a specific chemical in it. We hook the part up to the positive side of the power supply. When we turn on the power, a protective layer of aluminum oxide forms on the part.
Powder Coating: We use a special piece of equipment to spray powder coatings onto metal parts.
Paint spraying: We spray primer to help the final coating stick better and to help keep the part from rusting.
Inspection & quality control
- When we start a new batch, we take the first sheet metal part that comes out of the machine and inspect it to make sure it meets all the parameters and quality standards we need.
- As we’re making parts, we do spot checks to make sure we’re hitting the quality control points of the critical operations like cutting, bending and welding.
- Use calipers, vernier, salt spray tester, high and low temperature tester, CMM and other tools, film thickness gauge, test the size and geometry of sheet metal parts to ensure compliance with the drawing requirements.
- After the sheet metal parts are painted, plated or have some other kind of surface treatment, we check them to make sure the finish is good, the color is consistent and there are no defects.
Integrity Check: A final look at the sheet metal part as a whole and in detail, including its structural integrity, weld joints, and how well it fits together.
Functionality testing: If needed, we’ll do functionality testing to make sure the sheet metal part does what it’s supposed to do in the way it’s supposed to do it.
Packaging Inspection: We’re going to make sure the sheet metal parts are not damaged before they get packaged and that they’re packaged in a way that will keep them from getting damaged while they’re being shipped.
assembling
- Examine the assembly drawings carefully to figure out how each part connects to each other and the order in which they go together.
- Use the assembly drawings and the product structure to come up with a good way to put the thing together so that it goes together fast and right.
- Put each piece of sheet metal where it goes according to the drawing and temporarily hold it there with a clamp or something.
- Connect and secure the pieces with screws, rivets, welding or glue, depending on what the drawing says to do. After each connection, make sure it’s tight and in the right place.
Functional testing: Test the assembled products to make sure they work. For example, check that the moving parts move the way they’re supposed to, make sure the things that are supposed to be stable are stable, etc. Make sure the products work like they’re supposed to.
Surface treatment and cleaning: Put the final surface treatment on the assembled products. For example, paint or varnish them if they need it. Clean the products to get any stains or fingerprints off that happened during assembly.
Packaging & Shipping
- Do a final check of the sheet metal parts before you put them in the box to make sure they’re the right size, you have enough of them, and they look good. Wipe off the parts to get rid of dust, oil, or other stuff so they’re clean.
- Put something on the parts that can get scratched. You can put a film on them, use foam, or do something else to protect them.
- If the parts can get wet, put something in the box with them to keep them dry. You can use stuff called desiccant, and you can wrap the parts in plastic to keep the water out.
- Put something in the box with the parts to keep them from bumping into each other and breaking. You can use foam, bubble wrap, or stuff called an anti-vibration shim.
Boxing or Palletizing: Depending on the size and shape of the sheet metal parts, we’ll pick the right cartons, wooden crates, boxes, or wooden pallets to put them in. If they’re big or heavy, we’ll put them right on a pallet and wrap them with that plastic wrap.
Filler: We’ll use filler materials like foam peanuts, or shredded paper to fill in the empty spaces to make sure the product doesn’t move around and is stable during transportation.
Load packaged sheet metal parts into trucks or containers, depending on whether they’re going by land, sea or air. Make sure they’re secure, using straps or other fasteners as needed.
Estimated Cost Analysis For Sheet Metal

$1,000The Process Flow & Duration Estimation
Please note that how long it takes to get your final product done depends on how complicated your custom is, how many steps there are, what you need specifically, how many you’re doing, and how long it takes to ship it.
Step 1: R&D drawings (3-7 days)
During the design phase, you’ll create the initial design drawings and do a feasibility analysis of the manufacturing process. This is where you make sure your design works both aesthetically and functionally and can be created with the technology you have access to. The length of this phase will depend on the complexity of your project and how many technical problems you need to solve.
Step 2: Sampling (7-14 days)
Once we’ve got the design nailed down, we move into the prototyping phase. This is where we make a few samples to test how the design works in the real world and how the manufacturing process is going to work. We may have to do this a few times, depending on how complicated the samples are and how many changes we have to make.
Step 3: Pay The Bill (within 1 day)
Payment terms vary depending on the supplier and the customer. Some suppliers may require a partial deposit before they start making your stuff. Others may require full payment when you confirm the sample.
Step 4: Bulk Manufacturing (30-45 days)
Once you’ve approved the samples and finished all the prep work, it’s time to move into production. The length of time it takes to produce your order will depend on the number of units you’re ordering, how efficient your production line is, and if you have any special processes. This step can take the longest, especially if you’re doing a big order.
Step 5: Shipping (10-45 days)
After you’re done making your product, you need to pack it up and ship it to your customer. How long it takes to get to them depends on how far away they are, what shipping method you choose (like air or sea), and what the shipping situation is like right now.
